checking list empty python code example
Example 1: python list empty
my_list = list()
# 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**
if not my_list:
pass # the list is empty
