Is it possible only to declare a variable without assigning any value in Python?

Question

Is it possible to declare a variable in Python, like so?:

var

so that it initialized to None? It seems like Python allows this, but as soon

Answer 1

var_str = str()
var_int = int()

Answer 2

If I'm understanding your example right, you don't need to refer to 'value' in the if statement anyway. You're breaking out of the loop as soon as it could be set to anything.

value = None
for index in sequence:
   doSomethingHere
   if conditionMet:
       value = index
       break
