The exact same code in Python works fine, the variable name is used
outside of the if block even it has been declared inside.
This does not look right to me.
I'll try another way of explaining it. You seem to be confused that the
scope of the variable assignment[*] continues after the if. However,
look at this:
def f():
a=3
f()
a
NameError
Traceback (most recent call last)
<ipython-input-3-60b725f10c9c> in <module>()
----> 1 a
NameError: name 'a' is not defined
So the "def f()" obviously introduces local scope, but control
structures like if and while do not.

[*] In Python it's called "name binding", but it mostly works like
variable assignment
