请在Person类的基础上实现派生类Student,在学生类中增加新的SetInfo和ShowInfo方法,实现学生信息的输入和显示。
向量加法(add)、减法(sub)、乘法(mul,multiply n)、除法(div,divide by n)三个维度的实现。(类实现)
运算结果如图
class Person(object):
def __init__(self):
self.__name = '1' # 姓名
self.__age = '18' # 年龄
self.__sex = '男'
self.__major='计算机'
class Student( Person):
def SetInfo(self, name, age, sex,major):
self.__name = name # 姓名
self.__age = age # 年龄
self.__sex = sex
self.__major=major
def ShowInfo(self):
print(self.__name+" "+self.__age+" "+self.__sex+" "+self.__major)
stu = Student()
n=input("please input the name of student:")
a=input("please input the age of student:")
s=input("please input the sex of student:")
m=input("please input the major of student:")
stu.SetInfo(n,a,s,m)
stu.ShowInfo()
第二个
l1=[]
l2=[]
l1=input('the first vect:').split(',')
l2=input('the second vect:').split(',')
n=input('the n:')
print('the result is:',end="")
for i in range(len(l1)):
print(str(int(l1[i])+int(l2[i])),end=" ")
print()
print('the result is:',end="")
for i in range(len(l1)):
print(str(int(l1[i])-int(l2[i])),end=" ")
print()
print('the result is:',end="")
for i in range(len(l1)):
print(str(int(l1[i])*int(n)),end=" ")
print()
print('the result is:',end="")
for i in range(len(l1)):
print(str(int(l1[i])/int(n)),end=" ")
class Person():
def __init__(self, name, sex = '男'):
self.name = name
self.sex = sex
class Student(Person):
def __init__(self, name, sex = '男'):
super(Student, self).__init__(name, sex)
def SetInfo(self, age):
self.age = age
def ShowInfo(self):
print(self.name, self.sex, self.age)
class vect:
def __init__(self, *v):
self.v = v
def __add__(self, vt):
if len(self.v) != len(vt.v):
return "error"
else:
return vect(*[vt.v[i]+value for i,value in enumerate(self.v)])
def __str__(self):
return ','.join(map(str, self.v))
def __repr__(self):
return ','.join(map(str, self.v))
s1 = Student('小明', '女')
s1.SetInfo(34)
s1.ShowInfo()
v1 = vect(1, 2, 3)
print('the first vect:', v1)
v2 = vect(2, 3, 4)
print('the second vect:', v2)
v3 = vect(4, 5, 6)
print('the third vect:', v3)
print('the sum is:', v1 + v2 + v3)
其它的差,积,商仿照即可
