Check if list is empty in Python by comparing it with an empty list
code
# empty list & non-empty list
empty_list =[]
non_empty_list =[1,2,3,4]# check if list is emptydefcheck_list_empty(lst):if lst ==[]:print('The List is empty')else:print('The list is not empty')# pass in the lists to check_list_empty
check_list_empty(empty_list)
check_list_empty(non_empty_list)#Output
The listis empty
The List isnot empty
Check if list is empty in Python Using the len() method
code
# empty list & non-empty list
empty_list =[]
non_empty_list =[1,2,3,4]# check if list is emptydefcheck_list_empty(lst):iflen(lst)==0:print('The List is empty')else:print('The list is not empty')# pass in the lists to check_list_empty
check_list_empty(empty_list)
check_list_empty(non_empty_list)#Output
The listis empty
The List isnot empty
