无法在Python中划分两个字典

dict1 = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
dict2 = {}
dict3 = {}
for key, value in dict1.items():
    if value % 2 == 0:
        dict2[key] = value
    else:
        dict3[key] = value
print(dict2)  # 输出：{'b': 2, 'd': 4}
print(dict3)  # 输出：{'a': 1, 'c': 3, 'e': 5}

dict1 = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
dict2 = {key: value for key, value in dict1.items() if value % 2 == 0}
dict3 = {key: value for key, value in dict1.items() if value % 2 != 0}
print(dict2)  # 输出：{'b': 2, 'd': 4}
print(dict3)  # 输出：{'a': 1, 'c': 3, 'e': 5}

import itertools

dict1 = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
dict2 = {}
dict3 = {}
for condition, items in itertools.groupby(dict1.items(), lambda x: x[1] % 2 == 0):
    if condition:
        dict2 = dict(items)
    else:
        dict3 = dict(items)
print(dict2)  # 输出：{'b': 2, 'd': 4}
print(dict3)  # 输出：{'a': 1, 'c': 3, 'e': 5}
