Click on the link for Python 2. You will then see this page:. If you're using a Microsoft Windows operating system, click on the link to the file: Python If you're using any other operating system, scroll down under the heading Download the release for further instructions. The remainder of this document assumes you're using a Windows operating system.
This document is specific to Windows 98, but other Windows operating systems operate in a very similar manner. You will then see this screen:. Click on the Open button to start the download. When download of Python Choose the default settings. If you chose the default settings during installation, the Python software will be installed to the following folder:. The python interpreter is file:. Run the Python interpreter. Please note: the screen shots shown are generated from a computer running the Windows 98 operating system.
If you have another version of Windows the screens may look slightly different, but the procedures you should follow are the same. You can run the Python interpreter in a number of ways:. Running Python - Method 1. Suppose we use our favorite text editor again, to create a file of Python code called brian :.
We put the special line at the top of the file to tell the system where the Python interpreter lives. Technically, the first line is a Python comment. All comments in Python programs start with a and span to the end of the line; they are a place to insert extra information for human readers of your code.
We also called this file simply brian , without the. Adding a. Not to worry: just use the module file technique from the previous section. In fact, if you want to run files portably between Unix and MS-Windows, your life will probably be simpler if you always use the module file approach, not Unix-style scripts, to launch programs. On some systems, you can avoid hardcoding the path to the Python interpreter by writing the special first-line comment like this:!
When coded this way, the env program locates the python interpreter according to your system search-path settings i. But in some specialized domains, Python code may also be run by an enclosing system. In such cases, we say that Python programs are embedded in i. The Python code itself may be entered into a text file, stored in a database, fetched from an HTML page, and so on. In this code snippet, a program coded in the C language somefile. C programs may also gain access to Python objects, and process or execute them using other Python API tools.
Regardless, you can still use the interactive and file-based launching techniques described here, to test code in isolation from those enclosing systems that may eventually use it. Finally, depending on which type of computer you are using, there may be more specific ways to start Python programs than the general techniques we outlined above.
For instance, on some Windows ports of Python, you may either run code from a Unix-like command-line interface, or by double-clicking on Python program icons. When typing Python programs either interactively or into a text file , be sure to start all your unnested statements in column 1. Until the middle of Chapter 3 , all our statements will be unnested, so this includes everything for now.
This byte-code compilation step is hidden and automatic, and makes Python faster than a pure interpreter. Skip to main content. Let's try it! With your PowerShell command line open, enter python to run the Python 3 interpreter. Some instructions prefer to use the command py or python3 , these should also work. There are several built-in methods that allow you to make modifications to strings in Python. Press Enter for a new line.
Print your variable with: print variable. This will display the text "Hello World! Find out the length, how many characters are used, of your string variable with: len variable. This will display that there are 12 characters used. Note that the blank space it counted as a character in the total length. Convert your string variable to upper-case letters: variable. Now convert your string variable to lower-case letters: variable. Count how many times the letter "l" is used in your string variable: variable.
Search for a specific character in your string variable, let's find the exclamation point, with: variable. This will display that the exclamation point is found in the 11th position character of the string. Replace the exclamation point with a question mark: variable. Hope you had fun using some of Python's built-in string modification methods. Now try creating a Python program file and running it with VS Code. The VS Code team has put together a great Getting Started with Python tutorial walking through how to create a Hello World program with Python, run the program file, configure and run the debugger, and install packages like matplotlib and numpy to create a graphical plot inside a virtual environment.
Open PowerShell and create an empty folder called "hello", navigate into this folder, and open it in VS Code:. By starting VS Code in a folder, that folder becomes your "workspace". VS Code stores settings that are specific to that workspace in. Pygame is a popular Python package for writing games - encouraging students to learn programming while creating something fun. Pygame displays graphics in a new window, and so it will not work under the command-line-only approach of WSL.
However, if you installed Python via the Microsoft Store as detailed in this tutorial, it will work fine. Once you have Python installed, install pygame from the command line or the terminal from within VS Code by typing python -m pip install -U pygame --user. Navigate to this folder and create a file named "bounce. Open the folder in VS Code:. Read more about writing games with pygame at pygame.
