[Raymond Hettinger]
the current idiom:
mylist[:] = [] # clear
[Fred L. Drake, Jr.]
Unless you happen to prefer the other current idiom:
del mylist[:]
Or my personal favorite,
while mylist:
del mylist[::2]Then the original index positions with the most consecutive trailing 1 bits survive the longest, which is important to avoid ZODB cache bugs .
