Do iteration variable exist after the iteration statement in python?

Question

I have tried this code :

for i in range(10)
    print(line, i)

print(line, i)

and the program executed without error, so why is i declared even after the for statement, it must no longer exist.

have a look at this question http://stackoverflow.com/questions/3611760/scoping-in-python-for-loops — mathematical.coffee, Jan 27 '14 at 23:49

The scope is within a function, not a loop. A little different than other programming languages.

Yes, your iteration variable isn’t deleted when the loop is finished. As the documentation puts it: „Names in the target list are not deleted when the loop is finished”.

This has to do with variable scopes. As has been pointed out, the variable i exists within the scope of the function you’re in. A loop does not create an extra scope in python.
