Vinay Jaiswal Remove the parentheses from list(): if type(x) is list:

Also, you can check it using isinstance (variable, datatype) More about isinstance in https://www.w3schools.com/JUMP_LINK__&&__python__&&__JUMP_LINK/ref_func_isinstance.asp

as per Seg Adamyan post, but you need to be very specific var = 2 print(isinstance(var,int)) print(isinstance(var,str))

Vinay Jaiswal Try this as per visph suggestion def define(x): return type(x) print(define(2)) print(define('abc')) print(define([2,3,'a','b'])) PS: Had a glitch before, sorry if strange message got sent

Like. "def check(x): if type(x) is list(): print("Is of type list") else: print("This is of another type")" I know logic is wrong.But which logic i apply.

type() function can be used to determine which data type class
