Given an object, the task is to check whether the object is list or not. Method #1: Using isinstance
Python3
# Python code to demonstrate# check whether the object# is a list or not# initialisation listini_list1 = [1, 2, 3, 4, 5]ini_list2 = '12345'# code to check whether# object is a list or notif isinstance(ini_list1, list): print("your object is a list !")else: print("your object is not a list") if isinstance(ini_list2, list): print("your object is a list")else: print("your object is not a list") |
Output:
your object is a list ! your object is not a list
Method #2: Using type(x)
Python3
# Python code to demonstrate# check whether object# is a list or not# initialisation listini_list1 = [1, 2, 3, 4, 5]ini_list2 = (12, 22, 33)# code to check whether# object is a list or notif type(ini_list1) is list: print("your object is a list")else: print("your object is not a list")if type(ini_list2) is list: print("your object is a list")else: print("your object is not a list") |
Output:
your object is a list your object is not a list
Method #3: Using __class__
To check if an object is a list , you can use the __class__ attribute and compare it to the list type:
Python3
# initializing listini_list1 = [1, 2, 3, 4, 5]ini_list2 = (12, 22, 33)# code to check whether object is a list or notif ini_list1.__class__ == list: print("ini_list1 is a list")else: print("ini_list1 is not a list")if ini_list2.__class__ == list: print("ini_list2 is a list")else: print("ini_list2 is not a list")#This code is contributed by Edula Vinay Kumar Reddy |
Output
ini_list1 is a list ini_list2 is not a list
