In Python, why is list[] automatically global?

Question

This is a weird behavior.

Try this :

rep_i=0
print \"rep_i is\" , rep_i
def test():
  global rep_i #without Global this gives error but list , dict ,         


        

Answer 1

You only need to use global if you are assigning to the global name. Without global, an assignment creates a new local.

There's nothing special about how global applies to a list—global simply influences scope and name resolution.
