How do I check if a list is empty in Python?

Question

Aryan Kumar · Answer

In Python, you can check if a list is empty using the built-in len() function, or by checking the boolean value of the list itself. Here are two examples:

my_list = []  # An empty list
# Method 1: Using the len() function
if len(my_list) == 0:
   print("The list is empty")
# Method 2: Checking the boolean value of the list
if not my_list:
   print("The list is empty")

In the first example, the len() function is used to check the length of the list. If the length is equal to 0, then the list is empty.

In the second example, the boolean value of the list is checked. An empty list has a boolean value of False, so the not operator is used to check if the list is empty.

Both methods are equivalent, and you can use whichever method you prefer.

Hello this is Gulshan Negi

Well, using Python's built-in len() function or the list's boolean value, you can determine whether a list is empty.

Here's an example using the len() function:

my_list = []
if len(my_list) == 0:
   print("The list is empty")
else:
   print("The list is not empty")

Hope it will work for you

Thanks

We can use the Pythonic method of checking if a list is empty using its implicit booleanness. This is shown below in the case of an empty list: If the list is not empty:
