Declare variable as global inside block name == "main"

Question

Inside the block

if __name__ == "__main__":

do I need to declare a variable as global in order to set its value?
Or... is this block not a function and hence I don't need to do this?

I guess the latter is true but I want to double-check and make sure I understand this better.

It is not a function. Please read [mcve] for creating a more clear question. — ParthS007, Jun 22 '20 at 21:09
There's nothing special about `if __name__ == "__main__":`, it is the same `if` construct as `if True:` with respect to scope. It is **definitely not a function** — juanpa.arrivillaga, Jun 22 '20 at 21:10
`if` block does not have its own context. Does not matter what it's used for. — PM 77-1, Jun 22 '20 at 21:10

You just need to declare the variable, global keyword only makes sense in a function.

It's declared in the global scope, outside of all function bodies. – peter.petrov Jun 22 '20 at 21:12

if __name__ == "__main__"

This if statement does not have its own context, therefore variables can be modified without the need for the global keyword.
