for loop without variable

It depends how the code is written.  In the example such as:

for meaningless_variable in xrange(number_of_attempts):
    ...

the loop variable really has no meaning.  Rewriting this code only to
appease pylint is exactly that, it has nothing with making the code
more readable.

This loop contains more code and hence more opportunities for
introducing bugs.  For example, if you use "continue" anywhere in the
loop, you will do one retry too much.
