Code not working

Question

def main(me,friend)
print("hey!")

main("x","y")

when I run this...I get output as

hey!
None.... what's the mistake?

Answer 1

Put colon on the definition of main

def main(me,friend):
print("hey!")

Answer 2

@Moksh: you can't recognise a function that returns nothing?

@Sk: Basically, when a function doesn't have a return statement, it (implicitly) returns None. As your function doesn't have a return, it returns None.

Answer 3

@Moksh I expected output to be x & y....& @amaras I tried using return still getting no output.... can u alter the code to get the desired result?? I want output as X & Y

Answer 4

def main(me,friend):
print(main("x","y"))

return main

result is ...Indentation error for return

Answer 5

@moksh: why say print(str(me),str(friend))?

does it by default not mean that arguments inside the parentheses act as variable to values assigned to them within the function??

Answer 6

@Moksh...got it...thank u:)
