Python deletes elements from list

Paul's classmates had to turn away a few days ago, so how do we remove Paul from the existing list?

If Paul's classmates were in the last one, we could delete them using the list pop() method:

>>> L = [' Adam ', ' Lisa ', ' Bart ', ' Paul ']>>> L.pop () ' Paul ' >>> print l[' Adam ', ' Lisa ', ' Bart ']

The pop () method always deletes the last element of the list, and it returns the element, so we print out ' Paul ' after we execute L.pop ().

What if Paul's classmates aren't the last one? For example, Paul is ranked third:

>>> L = [' Adam ', ' Lisa ', ' Paul ', ' Bart ']

To kick Paul out of the list, we have to locate Paul's position first. Since Paul's index is 2, use Paul to erase it  pop(2) :

>>> L.pop (2) ' Paul ' >>> print l[' Adam ', ' Lisa ', ' Bart '
