Why does the console returns None in the program below:

Question

Hi i have started learning python3 with sololearn. Im having difficulties in some area.
def my_func():
print('Hi!')

Var = my_func()
print(var)

I dont understand why this program returns none along with Hi! as output. Can anybody put some light on this?

Answer 1

The function my_func doesn't return anything, so var gets set to None. If you want it to become something different, you can add a return statement to the end of the function. For example:

def my_func():
return "Hi!"

var = my_func()
print(var)

This will print Hi!, and nothing else.
