Hi. This must be a simple command but I just can't find it in the
Phthon manual. How do I delete all items with a certain condition from
a list? For instance: > L=['a', 'b', 'c', 'a']
I want to delete all 'a's from the list. > But if L.remove('a')
only deletes the first 'a'. How do you delete all 'a's?
L2 = list(set(L))
works for me...
For a very strange definition of "works":
py> L = ['a','b','c','a','j','b','z','b','a']
py> L2
['a', 'c', 'b', 'z', 'j']
py> L2 = list(set(L))
py> L2
['a', 'c', 'b', 'z', 'j']
I still see an 'a', there are things missing, and the order is totally
lost.
