is Python return always necessary -

this question has answer here:

• python — return, return none, , no return @ all 3 answers

i stumbled across several python programs written different people , noticed every function had return @ end of it

def function01():     # function     # events     # here     return 

i wondering if it's python programming practice include return @ end of functions if not returning (purely way of ending function)

or not needed , nothing different happen in background?

no, not necessary. function returns after last line. there no difference between simple return , no return.

def foo():     pass  def bar():     pass     return  f = foo() print(f) b = bar() print(b) 

output:

none none
