You know, sometimes it annoys me to write a for loop in Python. If we
use a list a=[1,2,3,4], and want to loop through it, Python offers the

for i in a:
print i

2

I love this. So simple and smooth. But what happens if we need also
the position of an object in a list. Then there comes this annoying
writing.
for i in range(len(a)):
print a[i], i
1 0
2 1
3 2
4 3
I think that it would be great if the Python language, which is a
totaly OOP language, could also use the index variable from the first
example and consider it as an object with a Object variable. I mean
the following.
for i in a:
print i, i.index # i.index is my sugesstion
1 0
2 1
3 2
4 3
I think that this would be great and we cou pass by this annoying
"range(len(a))" functions
Adding a random new attribute to arbitrary objects any time they happen
to end up in a for loop would be catastrophically terrible. Consider
the enumerate builtin, instead.
for i, e in enumerate('abcd'):
... print i, e
...
0 a
1 b
2 c
3 d
