Functions in python

In your Python Basics journey, you’ve probably encountered functions such as print (), len (), and round (). These are all built-in functions because they come built into the Python language itself.

A function in Python must be defined before it’s used. Create a function by using the keyword “def” followed by the functions name and the parentheses (). The function has to be named plus specify what parameter it has (if any). A function can use a number of arguments and every argument is responding to a parameter in the function. … Python bool () Function.
