Assigning keys to a dictionary from a string

Question

I have a string called sentence: \'the sly fox jumped over the brown dog\'

I need to create a dictionary called Positions. The key

Answer 1

since the character might be repeated in string, i am storing them as a list

str = "the sly fox jumped over the brown dog"
char_items = list(str) 
dictionary = {}

for index,character in enumerate(char_items): 
    if character not in dictionary.keys():
        dictionary[character] = [] # because same character might be repeated in different positions
    dictionary[character].append(index)

for character,positions in dictionary.items():
    print(character, positions)
