Return while defining functions (Python)

Question

Hi, can someone explain me what does Return mean in Python?

Answer 1

A function is like an operator.
3 + 5 returns the value 8
That 8 will disappear after you use the operator unless you do something with it, e.g. print it, like
print(3 + 5) # prints 8
This is the same as
def add_2_nums(a, b):
return(a + b)
If you call this function without doing anything with the returned value, it disappears, but you see it if, e.g., you print it.
print(add_2_nums(3, 5)) # prints 8

Functions are just a useful way to make a combination of operations if you are going to use them more than once (they help to keep your code DRY - Don't Repeat Yourself). They can include other functions you have defined, e.g.

def average_2_nums(a, b):
return sum_2_nums(a, b) / 2

print(average_2_nums(3, 5)) # prints 4.0

I.e you don't have to print every returned value - you can use it for something else.

In real life you would just define the last function as follows, because it uses less code, but you get the idea:

def average_2_nums(a, b):
return (a + b) / 2

Answer 2

return-this element of function(def),if function has only one line,and this line return,function return the text or line you write and stop cycle
