# Check if a list is empty by its length
if len(my_list) == 0:
    pass  # the list is empty
# Check if a list is empty by direct comparison (only works for lists)
if my_list == []:
    pass  # the list is empty
# Check if a list is empty by its type flexibility **preferred method**

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 empty
def check_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 list is empty
The List is not 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 empty
def check_list_empty(lst):
    if len(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 list is empty
The List is not empty
