Day6：Python基础：字典相关作业

 

# DIC = {'Name':'Alex'}
# #增：第一种
# DIC['Age'] = 21 #存在就覆盖，就是改
# print(DIC)
#
# #增：第二种
# DIC.setdefault('Tel' , '18616971010')   #没有就增加，存在什么都不做
# print(DIC)
#
#
# #删除一
# D = DIC.pop('Name') #有返回值，默认返回None,有值时返回键值
# print (DIC)
# print(D)
# #删除二
# del DIC['Tel']
# print (DIC)
#
# #清空字典
# L = DIC.clear()
# print(L)
#
# #改upate
# DIC1 = {'Name':'Alex',
#         'Age':80,
#         'Tel':18616971010
#         }
#
# DIC2 = {'Sex':'male'}
# DIC1.update(DIC2)
# print(DIC1)
