'Why do it get the value None when I use print(function()) [duplicate]

Trying to understand why this is happening. When I put tall() inside print(), it prints tall() but ALSO a None value. Why is the value None given after it has already printed out tall()?

def tall():
    print('31337')
print(tall())

Result:

31337
None

You must know that a function always return a value and in your case your function is not returning any value so the None value also.
