python调用类创建类

python调用类创建类

并行迭代

 names = ['a1', 'a2', 'a3']
    ages = [11, 22, 66]
    for i in range(len(ages)):
        print(names[i], 'is', ages[i], 'years old')
    list_conbine = list(zip(names, ages))

 

函数zip可用于“缝合”任意数量的序列

names = ['a1', 'a2', 'a3']
    ages = [11, 22, 66]
   
    list_conbine = list(zip(names, ages))
    for name, age in list_conbine:
        print('method2:', name, 'is', age, 'yeares old')

类的创建:

class Employee:
    __name = '' #下划线，表示私有private

    def set_name(self, name1):
        """

        :param name1:
        """
        self.__name = name1

    def get_name(self):
        """

        :return:
        """
        return self.__name

    def greet(self):
        """

        """
        print('hello, nice day ...')

 

类的调用：

class_emp = Employee()
    class_emp.set_name('tree')
    get_name = class_emp.get_name()
    print('员工的名字：', get_name)

 

if __name__ == '__main__':
    print_hi('good day')
    main()
    product_code = func_switch_case("bag")
    print(f"bag的产品编号：{product_code}")
    product_code = func_switch_case2("pencil")
    print(f"case2_pencil的产品编号：{product_code}")

    d = {'x': 1, 'y': 2, 'z': 3}
    for key in d:
        print(key, 'content:', d[key])
    names = ['a1', 'a2', 'a3']
    ages = [11, 22, 66]
    for i in range(len(ages)):
        print(names[i], 'is', ages[i], 'years old')
    list_conbine = list(zip(names, ages))
    for name, age in list_conbine:
        print('method2:', name, 'is', age, 'yeares old')

    class_emp = Employee()
    class_emp.set_name('tree')
    get_name = class_emp.get_name()
    print('员工的名字：', get_name)
