Each item of the list element gets printed line by line. Often it is desirable to loop over the indices or both the elements and the indices instead. Let us know if we missed anything while compiling this guide on loops – for in python index. 1. enumerate() function The pythonic solution to loop through the index of a list is using the built-in function enumerate().The function was introduced in Python 2.3 to specifically solve the loop counter problem.
