How to Check If A List Is Empty In Python?

4 minutes read

To check if a list is empty in Python, you can use the if statement and check the length of the list. If the length of the list is 0, then the list is empty. Here is an example code snippet:

1
2
3
4
5
6

my_list = []

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


Alternatively, you can also use the not keyword to check if the list is empty like this:

1
2
3
4

if not my_list:
    print("The list is empty")
else:
    print("The list is not empty")


Both methods will check if the list is empty and print the appropriate message.

What is the procedure to determine if a list is empty in Python?

To determine if a list is empty in Python, you can use the following procedure:

  1. Check the length of the list using the len() function:
1
2
3
4
5

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


  1. You can also use the bool() function on the list:
1
2
3
4
5

my_list = [] # empty list
if not bool(my_list):
    print("List is empty")
else:
    print("List is not empty")


  1. You can also use the list directly in a conditional statement:
1
2
3
4
5

my_list = [] # empty list
if not my_list:
    print("List is empty")
else:
    print("List is not empty")


All of these methods will check if the list is empty and print a message indicating whether it is empty or not.

How to efficiently verify the emptiness of a list in Python?

To efficiently verify the emptiness of a list in Python, you can simply use the following code:

1
2
3
4
5
6

my_list = []

if not my_list:
    print("List is empty")
else:
    print("List is not empty")


This code uses the not keyword to check if the list my_list is empty. If the list is empty, the condition not my_list will return True, and the message "List is empty" will be printed. Otherwise, the message "List is not empty" will be printed. This is a simple and efficient way to verify the emptiness of a list in Python.
