将字符串映射到以索引为键的字典中

Question

i am new in python coding, I am trying to map characters a strings into dictionary with index as key. I'm using a string "asleep" and want to get output as

{0: 'a', 1: 's', 2: 'l', 3: 'e', 4: 'e', 5: 'p'}

I'm using the following code:

myWord = "asleep"

char_count = map(lambda x: dict(enumerate(x)), myWord)

print(char_count)

Output:

{'a': 1, 's': 1, 'l': 1, 'e': 2, 'p': 1}

Answer 1

Simplest solution:

>>> word = 'asleep'
>>> dict(enumerate(word))
{0: 'a', 1: 's', 2: 'l', 3: 'e', 4: 'e', 5: 'p'}

This works because enumerate returns an iterable of pairs like (0, 'a') , (1, 's') , and so on; and the dict constructor works with an iterable of (key, value) pairs.

Answer 2

您可以尝试以下行：

dict(zip(range(len(myWord)), myWord))
