Python How To Empty / Clear A List

There are times where you might want to just wipe all of the contents of an entire list. Python gives us a built in function to clear a list which makes situations like this easy.

To clear a list just call clear:


list.clear()

You should probably use the above method in most cases but there are also a few other methods that you could use. We are going to take a look at these here.

Delete every element in the list:


del list[:]

Set every element to zero:


list *= 0

Reinitialize the list:


list = []
