python - 类型错误：不可散列类型：'sl​​ice' [python] [dictionaries]

Question

os.chdir("Güvenlik_Hesaplar")
files = ''
dictionary = {}
ant = os.listdir()
dict_number = 1
i = 0 

while i < len(ant): # If the variable 'i' is less than the length of my files
    dictionary["{}" : ant[i].format(dict_number)] #e.g = '1': 'myfile.txt'
    dict_number += 1
    i += 1
 

错误：

 File "C:\Users\Barış\Desktop\Python\prg.py", line 20, in passwordrequest
 dictionary["{}" : ant[i].format(dict_number)]
 TypeError: unhashable type: 'slice'

你能帮我解决这个问题吗？我正在使用 Windows x64

这是一个更好的方法：

import os

os.chdir("Güvenlik_Hesaplar")
dictionary = {str(k + 1): filename for k, filename in enumerate(os.listdir())}
