Absolutely, checking if a list is not empty in Python is a common operation. You can do this using various methods. Let's explore a few of them with code examples:
The len() function in Python returns the number of elements in a list. You can use it to check if a list is not empty by checking if its length is greater than zero.
In Python, empty lists evaluate to False in a boolean context, while non-empty lists evaluate to True. You can use this property directly in your code.
Explicitly comparing the list to an empty list is another way to determine if it's not empty.
All three methods achieve the same goal but offer different ways to express the condition. You can choose the one that best fits your coding style or the specific context of your program.
Remember, these methods work for lists, but they can also be adapted for other iterable types like tuples, sets, dictionaries, etc., to check if they are not empty.
