String to dict with duplicates

I think I am missing something basic here. I was trying to split a string into a dict with key as the index and value as the character.

instring = 'aabc'
stringmap = {instring.index(i): i for i in instring}

When I print stringmap: {0: 'a', 2: 'b', 3: 'c'}

I was expecting

{0: 'a', 1: 'a', 2: 'b', 3: 'c'}

What am I missing? The index values are right, but the duplicates are not part of the dict.

The index(i) method always returns the index of the first occurrence. That's why you get duplicate keys (i.e. zero for both instances of the letter a).

Simply feeding enumerate to the dict constructor will do the trick:

stringmap = dict(enumerate(instring))

Hey @sam You can solve your problem with this.

string = "sohaib"

{index:i for index,i in enumerate(string)}

Answer

{0: 's', 1: 'o', 2: 'h', 3: 'a', 4: 'i', 5: 'b'}
