This is almost definitely not the best way to do that, though it depends 
what results you're looking for.
This way will only replace the first occurrence of the item.
I don't know why you like the 'if item in ...' syntax so much ( ;) ), 
but you could do this with a loop pretty easily.
#example
for index,item in enumerate(lst):
    if item == 'Item To Replace':
       lst[index] = 'Replaced!'
