How to print number from user

[Larz60+]

print('Hello', + person)

remove the comma

I strongly recommend you start using the f-string method (first appears in python 3.6),
this is going to start showing up in all new code, so get used to it now and you will be in compliance later.
It is so much better that the old formatting methods.

also you get an indentation error because you have an indentation error.
all code should start in column 1 here. see: https://www.python-course.eu/python3_blocks.php
