How to let a loop run for a while before checking for break condition?

Sometimes it is known in advance, that the time spent in a loop will be in order of minutes or even hours, so it makes sense to optimize each element in the loop to make it run faster. One of instructions which can sure be optimized away is the check for the break condition, at least within the

Re: Middle matching - any Python library functions (besides re)?

If you want to avoid an O(n^2) algorithm, you may need to find a signature for each file. Then you use such signatures to compute hashes, and unique them with a dict (dict values may be the file names). Later you can weed out the few wrong collisions produced by the possibly approximated signature.

Re: Python-list Digest, Vol 35, Issue 410

Thank you Fredrik for answering.Actually the  "form.py"  was copied from an example inside one of the URL for non-programmer provided by python.org documentation site. I'm not familiar with the method to convert an MD5 token to it original state inside form.py. So, if I try to authenticate using re
