[New-bugs-announce] [issue44332] For Loop temporary variable scope should be local to For loop

[Debasis Satapathy]

New submission from Debasis Satapathy <deb_ctc at yahoo.co.in>:

numbers = [1, 2, 3, 4, 5, 6, 7, 8]
for x in numbers:
    print(x)
print(x)

In the above code, print(x) statement should give error. Because x scope should be local to for loop only.
99% cases, developers will not use the temporary variable x outside of the for loop.
So x will keep on consuming memory always. So it is a bad usage of memory.
Ideally x memory should be free once for loop execution is completed.
