# # 指定参数名,顺序可以与定义时不一致

# 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 *
