python自定义类用法
代码:
class Person:
def __init__(self, first, middle, last, age):
self.first = first;
self.middle = middle;
self.last = last;
self.age = age;
def __str__(self):
return self.first + ' ' + self.middle + ' ' + self.last +
' ' + str(self.age)
def initials(self):
return self.first[0] + self.middle[0] + self.last[0]
def changeAge(self, val):
self.age += val
myPerson = Person('Raja', 'I', 'Kumar', 21)
print(myPerson)
myPerson.changeAge(5)
print(myPerson)
print(myPerson.initials())
运行结果:
Raja I Kumar 21
Raja I Kumar 26
