一、字典生成式

二、zip()方法

keys = ['name', 'age', 'gender']
values = ['nick', 19, 'male']

res = zip(keys, values)
print(F"zip(keys,values): {zip(keys,values)}")

info_dict = {k: v for k, v in res}
print(f"info_dict: {info_dict}")
           

zip(keys,values): <zip object at 0x11074c088>

info_dict: {'name': 'nick', 'age': 19, 'sex': 'male'}
           

通過解壓縮函數生成一個字典

info_dict = {'name': 'nick', 'age': 19, 'gender': 'male'}

print(f"info_dict.keys(): {info_dict.keys()}")
print(f"info_dict.values(): {info_dict.values()}")

res = zip(info_dict.keys(), info_dict.values())

print(F"zip(keys,values): {zip(info_dict.keys(),info_dict.values())}")

info_dict = {k: v for k, v in res}

print(f"info_dict: {info_dict}")
           

info_dict.keys(): dict_keys(['name', 'age', 'gender'])

info_dict.values(): dict_values(['nick', 19, 'male'])

zip(keys,values): <zip object at 0x1105cefc8>

info_dict: {'name': 'nick', 'age': 19, 'gender': 'male'}
