You’re not alone if you don’t know how to use the Windows Command Prompt. Windows’ designers have made it difficult for non-programmers to use. However, it is still a very helpful tool for using applications like Python (so much so that the author made a tile for it above on the right).

Toaccess the command line, open the Start Menu via clicking the Start Button, lower left of the screen. Scroll the left side all the way down to Windows System – click the icon and sub menu items pop in, select Command Prompt with the black icon.

The Command Prompt does not put you in a REPL or IDLE, in contrast to the Python application mentioned on the previous page. You can carry out a variety of system operations using the Windows command line. Knowing where to locate the Command Prompt for system administration is helpful.

You can access Python in the Command Line by just typing python, python3, or python3.7, python3.8, or python3.9, depending on which version you installed. If you have more than one version installed, you’ll need to be more specific. You will then get the familiar REPL prompt.

Ifyou have not used Python before this and not installed the app as on the previous page, typing python may take you to the Microsoft Store to download the components. Follow the previous page if it does so.


Typing the word idle in the command prompt runs the IDLE Python editor, just like installing the app on the previous page. Rather than showing up in the command prompt window, a new IDLE window will appear (see image below).


The pip package manager, which opens up a world of open source packages to install for your projects, is also available for this installation of Python.

Typing pip3 list will list the currently installed packages. Consult the pip documentation (available at the link below) on all the commands used to work with packages with pip.


Python 3 on Windows now has a new, expanded world thanks to the Windows 10 May 2019 update.

How do you make a Python prompt? : In Python, we can get user input like this: name = input(“Enter your name: “) print(“Hello”, name + “!”) The code above simply prompts the user for information, and the prints out what they entered in.
What is name of the Python prompt? : Python’s prompt module, not a single function, performs this function. Every prompt type has a corresponding function with the prompt type’s name (e. g. , timely. prompt with text. prompt and list.

That >>> is called a prompt, which means it’s something the computer displays to tell you it’s readyfor your instructions. You can type things into that window, and the computer will obey them when it understands your commands.

It won’t comprehend it in the least. Instead, you must communicate with the computer using a special language that is intended to be simple for the computer to understand and, hopefully, for you to understand as well because the computer does not speak our language.

In fact, there are lots of languagesdesigned for computers and humans to communicate with each other. The one you’re going to learn is called Python. One of the good things about Python is that it’s pretty easy for humans to understand too.

Here’s how you ask the computer to tell you the sum of twelve and thirteen. Try it yourself. You don’t need to type in the >>>, but you do need to hit the key marked Enter after typing the line.

Here are some more examples, with the computer’s answers showntoo.

>>> 1 + 2 + 3 + 410>>> 1 + 2 * 3 - 4        # Use * for multiplication, not x.3                        # If you expected 5, think again!>>> 200 * 30060000>>> 12 / 4               # Use / for division.3.0

Play around with Python’s calculator functionality some more. Perhaps try making it do some more challenging tasks and experiment with larger and more numerous numbers. Does it move quickly, slowly, or both?

You can use parentheses to group operations — anything you use to manipulate a number, like + and * — in Python just as you do in mathematics:

Here, Python has added the results of (1 2) and (3 4) to get 3 and 7.

Experiment freely. Every time you discover a new Python function, experiment with small or significant changes and play around with it until you’re certain you understand exactly what’s happening. Don’t limit yourself to what is written on the sheets.

Incidentally, if you’re still confused about the fact that 1 + 2 * 3 - 4 gives 3 and not 5, the reason is that multiplication happens before addition.Your math teacher probably calls this BODMAS, PEMDAS, or something similar. If you’re still confused, try asking your math teacher to explain it to you.

Different types of objects¶

You’ve only ever worked with numbers so far. But Python isn’t just limited to handling numbers. Try the following, for example.

What did the computer actually do that you expected it to do?

Things between quotation marks are called strings. As you might guess from the lines above, you can apply operations like + to strings as well as to numbers. The plus sign concatenates strings; that is, puts one immediately after the other. A little more surprising:

You’ll notice that this time we haven’t told you what the machinesays. That’s because you’re supposed to try it for yourself. You won’t learn anything if you don’t try the examples. Write down in your notes what the machine said when you asked it for 3 * 'hello', so that you remember.

You can surround strings in either single quotes or double quotes; Python doesn’t mind.

>>> 'ham' + "mock"'hammock'

Why would you care about that? Well, suppose you wanted a string containing the text I'm sorry? Try it.

Python also has lists:

>>> [1, 2, 3][1, 2, 3]>>> [1, 2, 3] + [7, 8]

Again, we haven’t told you what Python says to that last thing. Write it down in your notes.

Giving names to things¶

Suppose you know that you’re going to need to do a lot of calculations involving the number 123456 — maybe it’s your annual salary, or something. You could just type thenumber in every time:

>>> 123456 * 3370368>>> 123456 / 620576.0>>> 123456 - 1000122456

This might get very boring after a while. And if anyone else wanted to read what you were doing, they might be confused by the mysterious number 123456 and wonder why it appeared so often.

You can solve either of these problems by giving the number a name. To save typing, give it a short name, like n — short for number, maybe. To make it more obvious what it means, give it a longer name, like salary. Here’s how youdo that.

>>> salary = 123456>>> salary * 4493824>>> salary / 1210288.0>>> salary123456

The idea is that, after you’ve said salary = 123456, you can always type salary instead of 123456. This is because the symbol = means is assigned to , not is equal to like you were taught in math class. So now 123456 is assigned to the word salary.

What we’ve called names, most people call variables. You’ll find out later why they’re called that. For now, names is fine.

You can name things other than numbers, too. Forinstance:

>>> my_name = 'Gareth'>>> 'Hello, ' + my_name + '!''Hello, Gareth!'

Doing something over and over again¶

So far, you’ve done very little that your pocket calculator couldn’t do equally well. Here’s something your calculator probably isn’t so good at. The extra spaces on the second line are important, by theway! This is explained in more detail in Sheet 2 (Turning the Tables).

>>> for x in 1, 2, 3, 4, 5:...     print(x, x * x)  # The prompt changes - Python is expecting more....                      # Just press Enter.

Can you guess what this will do?

Well done if you guessed correctly that it prints the numbers from 1 to 5 along with their squares. Observe how Python conveniently inserts a space between the two items you asked it to print.

The print command is used when you want to make the computerdisplay things. The reason you haven’t needed it before is that when you type it something that has an answer Python can work out, it automatically displays that answer. Things with answers are called expressions, for some reason. But Python doesn’t print out every value it computes; only the values of expressions you type in at the >>> prompt, and things you tell it to print out using the print command.

It’sall gone horribly wrong¶

At some point when you’re using Python, something like this is going to happen.

>>> 3 + 'aardvark'Traceback (most recent call last):  File "<stdin>", line 1, in <module>TypeError: unsupported operand type(s) for +: 'int' and 'str'>>>

This appears to be quite frightening. Don’t be alarmed. It’s simply Python’s way of telling you that you did something incorrectly. All but the final line can probably be ignored. Python uses the last line to inform us that it is unable to add a number to a string.

Look at Sheet E (Errors), which contains a list of common complaints Python might level at you and explanations of what they might mean, if you want to learn more about error messages in Python.

If what we really want is to join them together using string concatenation, we first have to convertthe number to a string:

>>> str(3) + 'aardvark''3aardvark'>>> str(7) + ' plus ' + str(3) + ' is ' + str(10) + '.''7 plus 3 is 10.'>>>

Putting things inside str(...) converts them into strings.

Writing programs in Python scripts¶

So far you have only been using the Python shell, the thing that gives you the prompt and waits for youinstructions. We will keep using the shell whenever we want to demonstrate new things Python can do.

The shell is less than ideal when we want to perform a great deal of tasks or the same task repeatedly. For starters, when you close it, it forgets what you typed. And you have to start over if you make a mistake when typing something lengthy.

When we want to write programs, we will put them in a text file using a text editor.

Your teacher will show you which editor to use and how to use it. The important thing to remember is to give your file a name that ends with .py so that your computer will know it is a Python script.


Write the following program in a file named firstprog.py:

print("Experiment 1: ")1 + 2print(1 + 2)"How come this did not print?"print("but this did?")print()print()print("Experiment 2:")for number in 2, 4, 6:    print(2 * number)for number in 2, 4, 6:    print(3 * number, end="")

Run the program and look carefully at its output. What happens when you put an expression on a line without a print command in a Python script? Does it print? What does putting acomma at the end of a print command do? What does putting a print command on a line by itself do?

Write down what you learned about printing. You will use this information often in the sheets ahead.


You can use Python for drawing pictures. Try this in a script. The first two lines willprobably seem rather weird; we’ll explain them later.

from gasp import *begin_graphics()Line((100, 100), (200, 200))Circle((320, 240), 40)Box((400, 300), 100, 85)update_when('key_pressed')end_graphics()

What next?¶

There are two kinds of worksheets for you to experiment with.

  • Activity sheets, each of which takes you through writing a program to do something that might be interesting. These sheets are numbered:Sheet 2 (Turning the Tables), Sheet 3 (Pretty Pictures) and so on — the sheet you’ve almost finished reading now is Sheet 1.
  • Information sheets, each of which tells you something useful about Python. These sheets are lettered:Sheet D (Dictionaries), Sheet L (Loops), or whatever. Usually the letters have something to do with what the sheets are about, but that hasn’t always been possible.
  • It’s usually a good idea to complete the activity sheets in order. Each one will direct you to a few information sheets, which you should have on hand while reading it. Sheet 2 (Turning the Tables) is the next one.

    How do you ask for input in Python? : Use Python’s built-in input() function to request user input. In addition to asking for straightforward string inputs like this, you should learn how to simultaneously request several inputs. Until a valid input is provided, keep asking for input.
    Read Detail Answer On How do you ask for input in Python?

    Throughout this course, we’ve looked at how to get information from the computer. Print statements are used to accomplish this. Print statements are essential for writing effective software because they show us what is happening in the program at any given moment.

    Almost all applications that you use on a daily basis will offer ways for you to give them information, but what about the opposite, what happens when we want to give the computer some information? Just look up atthe browser search bar above this website

    Programs that receive user input must be written in a specific way. The program will essentially ask the user for information, and after the user presses Enter, it will accept their input and use it to continue running the program.

    The code for accepting user input isactually not that much more complex than the code for printing. In Python, we can get user input like this:

    Copyname = input("Enter your name: ")print("Hello", name + "!")

    One of the most important things to note here is that we’re storing whatever the user entered into a variable. It’s vital that we do this, after all, what’s the point of asking the user for something if we’re not gonna keep track of it.


    As you experiment with this program, you’ll discover that it actually halts execution while it waits for user input. The programs we’ve written in the past seem to run and finish in a matter of milliseconds. However, in this instance, the computer will wait with you if you wait for 10 minutes before you decide to enter something.

    This is due to the fact that the computer pauses everything it is doing and waits when it recognizes that it is ready to accept input. In many instances, the user’s input is essential for the computer to be able to complete its task, whatever it may be.

    Many programs you’ll encounter (and eventually write) will rely on the user to tell them what to do and when it’s okay for them to stop. Once we discover more advanced topics we’ll eventually be able to write programs that have menus and give the user an option of what they want to do! But this is where it all starts.

    Wrapping Up

    Now that you understand the fundamentals, experiment a little to see if you can change the prompt or ask the user for more information while using some of the string functions we discussed in earlier lessons.

    About gathering user input, there is still much to learn. Right now, the only input we are getting is in the form of strings. We’ll look at how to allow the user to enter numbers and other types of data as we go further in the course.

    How do I run a Python script?

    Open a command line and type $ python3 hello to run a Python script. Alternatively, you can use python or python3 if you have both versions of the language installed. Hello, World!

    How do you prompt user for integer input in Python?

    Use Python’s built-in input() function to receive user-provided integer input. The string data that this input() function returns can be placed in a string variable. then convert it to an integer value using the int() function.
