[Tutor] question about removing items from a list

[Python Snake]

Many thanks to Lloyd and Allan for explaining the tricks behind for loop.

Anyway, if you really want to loop through the list and remove all the items
one by one, you may try something like this:

>>> lista = ['a', 'b', 'c', 'd']
>>> templist = lista[:]
>>> for item in templist:
...        lista.remove(item)
...
>>> lista
[]


Regards,

HY
