python-字典列表中删除指定的键值对

dict_list = [
    {"a": 1, "b": 2, "c": 3},
    {"a": 11, "b": 22, "c": 33},
    {"a": 111, "b": 222, "c": 333},
    {"a": 1111, "b": 2222, "c": 3333},
]

for d in dict_list: list(map(d.pop, "a"))
print(dict_list)

# [{'b': 2, 'c': 3}, {'b': 22, 'c': 33}, {'b': 222, 'c': 333}, {'b': 2222, 'c': 3333}]
