- Usually, we want to repeat a series of commands several times 
- One way to do this is to use a function 
Activity: CodeLens 2.2 (cl_l38_2b_en)
- Don’t forget parentheses when calling the function! 
- If you forget the parentheses, Python will return the memory address where the function is defined. 
Activity: CodeLens 2.3 (cl_l38_2c_en)
- We can put parameters in a function 
Activity: CodeLens 2.4 (cl_l38_2d_en)
- Functions cease to exist as soon as you exit the Python interpreter 
- Hence, programs generally consist of modules, which are files stored on disk 
- A module is a text file containing a Python program 
- You can edit modules in a development environment, which highlights reserved words, performs automatic indentation, etc. 
- We save a program called - chaos.py
- Don’t forget the - .pyextension
- We can run the program with the “Run” button.
