#判断变量是否为整数

money=120

print("{0}是{1}".format(money,getType(money)))

#判断变量是否为字符串

money="120"

print("{0}是{1}".format(money,getType(money)))

money=12.3

print("{0}是{1}".format(money,getType(money)))

#判断变量是否为列表

students=['studentA']

print("{0}是{1}".format(students,getType(students)))

#判断变量是否为元组

students=('studentA','studentB')

print("{0}是{1}".format(students,getType(students)))

#判断变量是否为字典

dictory={"key1":"value1","key2":"value2"}

print("{0}是{1}".format(dictory,getType(dictory)))

#判断变量是否为集合

apple={"apple1","apple2"}

print("{0}是{1}".format(apple,getType(apple)))
