Functions in Python#
In Python, a function is a named sequence of statements that performs a computation.
Key term: function
To execute a function, we call it by name and pass it an appropriate set of input arguments. A function takes zero or more arguments as inputs and returns zero or more outputs as a result. The output or result of a function is called the return value.
Key terms: function call, input argument, function output or return value
Data, parameters, or arguments can be passed into a function. Functions can also return data.
