If this worked, you know how to access Python on your system. Running Python in a Terminal Session Enter the following line in your Python session, and make sure you see the output Hello Python world! ") Hello Python world! >>> Any time you want to run a snippet of Python code, open a command window and start a Python terminal session. To close the terminal session, press ctrl-Z and then press enter, or enter the command exit(). Installing a Text Editor Geany is a simple text editor: it’s easy to install, will let you run almost all of your programs directly from the editor instead of through a terminal, uses syntax highlighting to color your code, and runs your code in a terminal window so you’ll get used to using terminals.

A syntax error occurs when Python doesn’t recognize a section of your program as valid Python code. For example, if you use an apostrophe within single quotes, you’ll produce an error. This happens because Python interprets everything between the first single quote and the apostrophe as a string. It then tries to interpret the rest of the text as Python code, which causes errors. Here’s how to use single and double quotes correctly. " print(message) The apostrophe appears inside a set of double quotes, so the Python interpreter has no trouble reading the string correctly: One of Python's strengths is its diverse community.

Exe installer or something similar. Run the installer and accept all the defaults. To start your first program, open Geany: press the Windows key and search for Geany on your system. You should make a shortcut by dragging the icon to your taskbar or desktop. Make a folder called python_work somewhere on your system for your projects. py in your python_work folder. py tells Geany that your file will contain a Python program. It also tells Geany how to run your program and to highlight the text in a helpful way.
