Python-readline()循环将所有行放入字典中的相同值槽中

您可以在Python中直接迭代每个文件行。看来你真正需要的是一份城市清单,而不是一本字典。

因此,您需要的可能是:

cities = []
with open("cities.txt", "r") as infile:
    cities = [city.rstrip('\n') for city in infile]

需要一个字典,然后使用索引作为键将列表转换为字典:

cities = []
with open("cities.txt", "r") as infile:
    cities = [city.rstrip('\n') for city in infile]

citydict = {index: city for index, city in enumerate(cities)}
