# def my_function1(name, address, age):
#     print('姓名：%s, 地址：%s, 年龄：%s' % (name, address, age))
#
# # 正确：
# my_function1('北京',50,'田老师')
#
# # 错误：
# my_function1(50, '北京', '田老师')
#
# # 指定参数名，顺序可以与定义时不一致
# my_function1(age=50, address='北京', name='田老师')
 
# 默认值
 
# 我们已知的情况：
# def my_function2(name, age):
#     print('姓名：%s, 年龄：%s' % (name, age))
# #
# my_function2('田老师')
 
# 一定场景下，带默认值
# def my_function2(name, age=18):
#     print('姓名：%s, 年龄：%s' % (name, age))
# #
# my_function2('张老师')
# my_function2('田老师', 46)
 
# 有默认值时的参数顺序
# 正确：
# def enroll(name, city='Beijing'):
#
#     print('name:', name)
#     print('city:', city)
#     print('-------------')
 
# def enroll(name, city='Beijing'):
#
#     print('name:', name)
#     print('city:', city)
#     print('-------------')
# #
# enroll('ShangHai')
 
# 以下的代码的输出什么? 你将如何修改 extendList 的定义所带来的隐患问题
# def extendList(val, list=[]):
#     list.append(val)
#     return list
 
# def extendList(val, list=None):
#     if list == None:
#         list = []
#     list.append(val)
#     return list
#
# list1 = extendList(10)          # list1 = [10]
# list2 = extendList(123, [])     # list2 = [123]
# list3 = extendList('a')         # list3 = ['a']
#
# print("list1 = %s" % list1)
# print("list2 = %s" % list2)
# print("list3 = %s" % list3)
 
# 隐患和修改方法：
# 函数定义时，如果参数有默认值，则在定义时就会开辟一块内存空间来存储该默认值
# 调用函数时，如果未给有默认值的参数传值，就会使用该内存空间的数据
# 多次调用时，该空间就会被重复使用，如果某一次调用时改变了该空间的数据，其他次调用也会收到影响
# 可变数据类型，内存空间内容可以被改变，所以尽可能不用可变数据类型
# 如果一定要用，默认值不要用空对象，应该用None
 
# 可变参数 *
# def my_function3(name, age, gender, *other):
#     print('name:', name)
#     print('age:', age)
#     print('gender:', gender)
#     print('other:', other)
#
# my_function3('田老师', 56, '男', '北京','慧测','汤立路220号','哈哈哈')
 
# 可变参数 **
# def my_function4(name, age, gender, **other):
#     print('name:', name)
#     print('age:', age)
#     print('gender:', gender)
#     print('other:', other)
# #
# my_function4('田老师',56, '男', city='北京', corp='慧测', address='汤立路220号')
 
# 参数顺序一般是非可选参数在前，可选参数在后
 
# 1 *
# def enroll(name, *other):
#
#     print('name:', name)
#     print('other:', other)
#
# enroll('zhanglaoshi', 18, '北京')
 
# 这样也可以，但不建议
# def enroll(*other, name):
#
#     print('name:', name)
#     print('other:', other)
#
# enroll( 'Beijing', 18, name='张老师')
 
# 2 **
# def enroll(name, **other):
#     print('name:', name)

# 3. (选做)编写一个生成get请求地址的函数，上游传递过来的参数有url=“”,domain=“”,data={}，
# 请根据以上参数返回一个get请求的完整链接，其中data和url有可能不传
