将字典中的所有值设为小写

Question

Python

如何使用字典（仅包含字符串）并将该字典中的所有值设为小写？

Answer 1

my_dict ={"first":"ABC","second":"abC","third":"aBc"}
for i in my_dict.keys():
    my_dict[i] = my_dict[i].lower()

更新（对于 list 作为字典值）：

my_dict ={"first":"ABC","second":"abC","third":"aBc","fourth":["Avd","Dfe"]}
for i in my_dict.keys():
    if type(my_dict[i]) is list:
        my_dict[i]=  [j.lower() for j in my_dict[i]]
    else:
        my_dict[i] = my_dict[i].lower()
print(my_dict)

输出：

{'first': 'abc', 'second': 'abc', 'third': 'abc', 'fourth': ['avd', 'dfe']}
