Hello. I don't in understand clearly about returning from function. Could you explain me more?

Answer 1

in a function sometimes you need get a value from that function so you have to return it from it. example:

def add(a,b):
c=a+b

def add2(a,b):
c=a+b
return c

result = add(10,20)
result2 = add2(10,20)

print("result "+result)
print("result2 "+result2)

"result "
"result2 30"

in the first case the function don't return the result so it is lose and the second function has a return so you can get it and you can use it then.

Answer 2

"return var" is like "print(var)" but in the most of cases you have to put "return" if you want to use it in other functions.
