Bug description
The code is:
series = [1, 2, 3, 4, 5]
output_list = [
(item, series[index])
for index, item in enumerate(series, start=1)
if index < len(series)
]
print(output_list)
Which produces the output:
[(1, 2), (2, 3), (3, 4), (4, 5)]
When there is a start parameter on the enumeration, "item" and "series[index]" are not the same object
but pylint suggests:
R1736: Unnecessary list index lookup, use 'item' instead (unnecessary-list-index-lookup)
If we follow the advice we would get a different result set
[(1, 1), (2, 2), (3, 3), (4, 4)]
I think the error should be suppressed when there's a start index on the enumeration
