I need to spit out those entries after trimming the last two characters, e.g. if the entry is 199902345 it should output 1999023 . I tried looking into TRIM but looks like it offers trimming only if we know what are the last two characters. But in my case, I don't know what those last two numbers are and they just needs to be discarded. So, in short, what MySQL string operation enables to trim the last two characters of a string? I must add that the length of the string is not fixed. It

There is an issue with finding the adjacent element on the last level on the binary heap when adding an element which can be resolved algorithmically ... Any ideas on how such an algorithm might work? I was not able to find any information about this issue, for most binary heaps are implemented using arrays. Any help appreciated. Recently, I have registered an OpenID account and am not able to edit my initial post nor

Any thoughts? d = {1:2, 3:4, 5:6, 7:8, 9:0} for x in d: if last item: # 回答1: Use enumerate : #!/usr/bin/env python d = {1:2, 3:4, 5:6, 7:8, 9:0} # If you want an ordered dictionary (and have python 2.7/3.2), # uncomment the next lines: # from collections import OrderedDict # d = OrderedDict(sorted(d.items(), key=lambda t: t[0])) last = len(d) - 1 for i, x in enumerate(d): if i == last: print i, x, 'last' else: print i, x # Output: # 0 1 # 1 3 # 2 9 # 3 5

I want to search the last 10 lines or so to see if any of them match a string. I need to do this as quickly and efficiently as possible and was wondering if there's anything better than: s = "foo" last_bit = fileObj.readlines()[-10:] for line in last_bit: if line == s: print "FOUND" 回答1: # Tail from __future__ import with_statement find_str = "FIREFOX" # String to find fname = "g:/autoIt/ActiveWin.log_2" # File to check with

Or list activities between two date ranges? 回答1: It is a bit trickey, because all cleartool lsactivity commands are limited to one pvob ("project vob" or "special vob with UCM metadata in it"): cleartool lsact -invob \my\pvob -stream ... And an activity can be reused (meaning an old activity can have in its changeset very recent versions) If you have two baselines, you can easily diff them (by activity): See .. diffbl **. ct diffbl -act baseline
