How to convert a list to a dictionary with indexes as values?

I am trying to convert the following list: l = ['A', 'B', 'C'] To a dictionary like: d = {'A': 0, 'B': 1, 'C': 2} I have tried answers from other posts but none is working for me. I have the following code for now: d = {l[i]: i for i in range(len(l))} Which gives me this error: unhashable type: 'list'
You can get the indices of a list from the built-in enumerate. You just need to reverse the index-value map and use a dictionary comprehension to create a dictionary: >>> lst = ['A', 'B', 'C'] >>> {k: v for v, k in enumerate(lst)} {'A': 0, 'C': 2, 'B': 1}
