Removal of element from list while traversing causes the next element to be skipped

[Matthew_WARREN at bnpparibas.com]

Hmm, how does this fare??

for i in range(len(a)):
      if a[i]==99: a=a[:i]+a[i+1:]


I like following your guys code noodling.  I can come up with something
that does what it appears your doing, sometimes, but as to it's relevant
merits I havent a clue :)

Or one can put on his bellbottoms, horn-rimmed glasses, and wear a mullet:

i = 0
while i < len(a):
  if a[i] == 99:
    del a[i]
  else:
    i += 1
