For loop Pits

(prevents the list element from being deleted when it loops)
= = cannot be traversed while deleting = =
It means that you can't delete a list of your own loops, you can delete others

The For loop iterates through a list and deletes an element that has a pit.

Just point to the next element

11 22 33 Deleted 33, 44 just entered a bit (fill up), so 44 did not delete

= = Write down the person who wants to delete.

a=[11,22,33,44,55]b=[]for i in a:    if i=33 or i=44:        b.append(i)for i in b:        a.remove(i)print(a)
