4.1.6 - Return from a Function

Return vs Print

Certain functions, such as int or str, return a value that can be used later. When a function returns a value the value is not printed in the output.
To return a value for your defined functions, you can use the return statement. The return statement cannot be used outside of a function definition.

Write the following code to Thonny script editor and save it as maxOfTwo:

	def max(x, y):
	if x >=y:
	return x
	else:
	return y

view raw maxOfTwo.py hosted with ❤ by GitHub

The function takes two arguments and returns the maximum of two without printing anything.

Execute the code and in CLI write the following commands and observe the Variables area :

>>> print(max(3,9))

>>> z = max(11,2)

>>> print(z)
