python怎么判断数据类型

#判断变量类型的函数

  def typeof(variate):

    type1 = ""

    if type(variate) == type(1):

        type1 = "int"

    elif type(variate) == type("str"):

        type1 = "str"

    elif type(variate) == type(12.3):

        type1 = "float"

    elif type(variate) == type([1]):

        type1 = "list"

    elif type(variate) == type(()):

        type1 = "tuple"

    elif type(variate) == type({"key1":"123"}):

        type1 = "dict"

    elif type(variate) == type({"key1"}):

        type1 = "set"

    return type1

#返回变量类型

  def getType(variate):

    arr = {"int":"整数","float":"浮点","str":"字符串","list":"列表","tuple":"元组","dict":"字典","set":"集合"}

    vartype = typeof(variate)

    if not (vartype in arr):

        return "未知类型"

    return arr[vartype]

#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)))
