[Tutor] Would somebody kindly...

[Clayton Kirkwood]

Ah, Alan sent an answer also, but this one answers the last tidbit. Alan had the some_list and pair the same name, presumably creating a temporary tuple and when the loop is done, the temporary replaces the original.

Thanks

!Hi Clayton,
!
!Here is a rewording of that expression to an approximately equivalent
!statement:
!
!#######################
!some_list = []
!for pair in values:
!    if key == pair[0]:
!        some_list.append(pair)
!#######################
