About None in Python

Question

def some_func():
print("Hi!")

var = some_func()
print(var)

My question is, why var does not return Hi! IF that already was defined when I write def some_func():
print("Hi!")

Can someone clarify it to me?

Thanks in advance :)

Answer 1

var doesn't return anything, var is the name you give for what the function returns.

And a function only returns something if you specify that. If you don't, var will be None.

So in the function you'd have to write:

return 'Hi!'

Then var would contain 'Hi!' and you could print it out as expected.

Answer 2

None is correct as your function doesn't return anything.

Answer 3

Var will return None

Answer 4

Since the function itself prints "Hi!" just call the function normally:

some_func()

No need to save it to a variable (var in this case).
