Functions should only perform a single task

Python Clean Code Tip:

Functions should only perform a single task

Hint: If your function contains the keyword 'and' you can probably split it into two functions.

# This is bad
def fetch_and_display_personnel():
    data = # ...

    for person in data:
        print(person)


# This is good
def fetch_personnel():
    return # ...

def display_personnel(data):
    for person in data:
        print(person)
