Running Python

Try:

• Saving some previous code as program.py
• Open a command-line interface in your computer and run: python3 program.py
  • You need to have python3 installed in your machine
  • You need to be in the directory of the file program.py

Python can be run in two modes:

Script / Program

• All lines of code executed without stop
• Run in command-line as python3 program.py
• Only print what is specifically passed through print()

Interactive shell

• Run lines of code each at a time, as user enters them
• Open in command-line just by typing python3
• Typing an expression without being assigned to a variable will “print” the result

Integrated Development Environment (IDE)

• In our classes, we will be using Thonny
  • Notice the panels for scripting and for interactive shell
  • There is also a helper and variable explorer for debugging code
