Multiple calls to a function are a very efficient way of working. In the function, the code for describing a pet is written only once. Then, if you wish to describe a new pet, you simply call the function with the information for the new pet. Even if the code for describing a pet expanded to five lines, calling the function again would allow you to describe a new pet in just one line.

Return values

A function's output doesn't always have to be displayed directly. It can instead process data and then return a value or group of values. The value the function returns is called a return value. The return statements takes a value from inside a function and sends it back to the line that call the function.

Example 1.

def username(first_name, last_name):

"""Return a full name"""

full_name = f"{first_name} {last_name}"

return full_name.title()

author = username('naseeb','akhter')

print(author)

Output:

Naseeb Akhter
