Note that "list" is the name of a built-in type; I used "mylist".
Alex Martelli described how to do it in log n time using the bisect
module. Here's a dumb linear time method that might be faster for
small n (of course you should time the different methods for your
particular Python implementation, if the speed matters):
del mylist[len(mylist) - mylist.count(0):]
The above an example of where the natural
del mylist[-mylist.count(0):]
does totally the wrong thing if there are no 0's in the list. There
was a huge thread a while back about ways to fix that.
Another way, might be faster, esp. there's more than a few 0's:
try:
del mylist[mylist.index(0)]
except ValueError:
pass # no 0's in the list
