Three ways to run code

Python can work like a simple calculator.

>>> 1 + 5 * 2 - 3
8
>>> (2 + 3) * 4
20
>>> 1.0 / 3.0
0.3333333333333333

You can run Python code in three common ways.

1. Interactive terminal

$ python3
>>> 1 + 5 * 2 - 3
8

2. Script file

# calculator.py
print(1 + 5 * 2 - 3)
$ python3 calculator.py

3. IDE or notebook

  • A VS Code Python file with the built-in terminal or Python extension
  • A Colab notebook cell
