# 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)

#     print('other:', other)

#

# # 调用时传参

# enroll(address='Beijing', age=18, name='张老师')

# 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

#         params_list = []

#         for k, v in data.items():

#             param = k + '=' + v

#             params_list.append(param)

#         params = '&'.join(params_list)
