Hi,
I am trying to convert a list of pairs (l4) to list l5 by removing those
pairs from l4 which are not present in a third list called pairList.
The following is a simplified part of the routine i have written. However
it does not give the correct output. Please help!
Its possible i have made a trivial mistke since i am a newbie.
def getl5():
l5 = []
pairList = [[1,2],[3,4],[3,5],[3,6],[9,7],[8,9],[8,7],[7,9],[11,10]]
l4 = [[4,2],[4,7],[4,10],[4,12],[9,2],[9,7],[9,10],[9,12],[11,2],[11,7]]
for pair in l4:
if pair not in pairList:
element.remove(l4)
l5.append(element)
print "l5 is",l5
