Key Concepts Explanation
Defining Functions
In Python, functions are defined using the def keyword followed by the function name and parameters enclosed in parentheses. The function definition ends with a colon :.
def add(a, b):
return a + b
Returning Values
Functions in Python can return values using the return keyword. This allows the function to produce output that can be used elsewhere in the code.
def multiply(x, y):
return x * y
