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".
