例如,如果我具有以下功能:
def to_full_name(first_name, last_name=None): # Note that 'last_name' is not required, so an error will not occur
return '{} {}'.format(first_name, last_name)
# ...
a = to_full_name('John')
如何在第二行后面将第二个参数添加到'a'变量中?例如:
a.set_argument('last_name', 'Doe')
答案 0 :(得分:1)
对于这个特殊的问题,我建议上一堂课。
class Person:
def __init__(self, first_name=None, last_name=None):
self.first_name = first_name
self.last_name = last_name
def set_first_name(self, name):
self.first_name = name
def set_last_name(self, name):
self.last_name = name
def to_full_name():
return '{} {}'.format(self.first_name, self.last_name)
然后我们将其更改如下
person = Person("John")
person.set_last_name("Doe")
print(person.to_full_name())
我们也可以直接更改值
person = Person()
person.last_name = "Doe"
person.first_name = "John"
print(person.to_full_name())
