How to delete list items in python iteration

This article is about how to delete list items in the python iteration. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

1. You can use list understanding to create a new list that contains only elements you don't want to delete.

Somelist = [x for x in somelist if not determine (x)]

2. Change the existing list to include only the items you want by assigning to slice somelist [:].

Somelist [:] = [x for x in somelist if not determine (x)]

3. This method can be useful if there are other somelist references that need to reflect the changes.

Besides understanding, you can also use itertools. In Python2:

From itertools import ifilterfalsesomelist [:] = ifilterfalse (determine, somelist)

Or in Python3:

From itertools import filterfalsesomelist [:] = filterfalse (determine, somelist) Thank you for reading! This is the end of the article on "how to delete list items in the python iteration".
