python 判断变量类型

使用  isinstance()函数，该函数有两个参数，第一个为填入的变量，第二个为类型（str，int，float，list，tuple，dict，set），返回值为布尔值

函数如下

def typeof(variate):
  type=None
  if isinstance(variate,int):
      type = "int"
  elif isinstance(variate,str):
      type = "str"
  elif isinstance(variate,float):
      type = "float"
  elif isinstance(variate,list):
      type = "list"
  elif isinstance(variate,tuple):
      type = "tuple"
  elif isinstance(variate,dict):
      type = "dict"
  elif isinstance(variate,set):
      type = "set"
  return type
