One line code for Converting list to dictionary values-CodePudding

Is there a one liner code for converting the following list/string to map, basically counting all chars and storing in map.

lst = 'leet'

map ={'l':1,'e':2,'t':1}

what i did so far

for i in lst:
    if i not in map:
        map[i] = 1
    else:
        map[i] =1

CodePudding user response：

Try

>>> from collections import Counter
>>> Counter("leet")
Counter({'e': 2, 'l': 1, 't': 1})

CodePudding user response：

from collections import Counter; c = Counter(lst) since you said must be one-liner :)

{letter: "leet".count(letter) for letter in "leet"} might work
