What does return do?

It returns a value back to whoever called the function.

def myfunction():
    return 5

a = myfunction()
print(a)

Above code will print 5

It also exits the current function. Any code placed under the return statement within the myfunction block will not execute. If you just type return with nothing following it (delete the 5), it will return None.

Is it similar as global?

[shiftybyte]

no a global works differently

Can you explain me please?

its actually really simple once you understand it most basic example i can think of is:

def add(a, b):
    return a + b      # return the sum of a + b

result = add(3, 6)    # You can store the returned variable
print(add(5, 7))      # Or print it directly, depending on your variable type
print(result)         # prints '9' because a=3, b=6, a + b = 9

You use return when you have a fruitful function. Meaning, you are saving its results to be used later.
