无法在函数中创建新的字典键值对

  • 772

无法创建新的 {'age' : age} 键值对。可能是什么问题呢？

def build_person(first_name, last_name):
    person = {'first': first_name, 'last': last_name}
    if age:
        person['age'] = age
    return person
musician = build_person('dan', 'balan', age = 23)
print('\n' + musician)
python

    您可以这样做：添加任意命名参数。或者如果您需要控制输入数据，请在函数中过滤此列表

    def build_person(first_name, last_name, **kwargs ):
    person = {'first': first_name, 'last': last_name}
    for x in kwargs:
        person[x] = kwargs[x]
    return person
musician = build_person('dan', 'balan', age = 23)
print(musician)   # {'first': 'dan', 'last': 'balan', 'age': 23}
