[Python 2.7] I have a body of text (~1MB) that I need to modify. I need to look for matches of a regular expression and replace a random selection of those matches with a new string. There may be several matches on any line, and a random selection of them should be replaced. The probability of replacement should be adjustable. Performance is not an issue. E.g: if I have:
SELECT max(PUBLIC.TT.I) AS SEL_0 FROM (SCHM.T RIGHT OUTER JOIN PUBLIC.TT ON (SCHM.T.I IS NULL)) WHERE (NOT(NOT((power(PUBLIC.TT.F, PUBLIC.TT.F) = cast(ceil(( SELECT 22 AS SEL_0 FROM (PUBLIC.TT AS PUBLIC_TT_0 JOIN PUBLIC.TT AS PUBLIC_TT_1 ON (ceil(0.46) =sin(PUBLIC_TT_1.F))) WHERE ((zeroifnull(PUBLIC_TT_0.I) = sqrt((0.02 + PUBLIC_TT_1.F))) OR I might want to replace '(max|min|cos|sqrt|ceil' with "public.\1", but only with probability 0.7. I looked and looked for some computed thing in re's that I could stick and expression, but could not find such(for good reasons, I know). Any ideas how to do this? I would go for simple, even if it's wildly inefficient, though elegance is always admired... -- http://mail.python.org/mailman/listinfo/python-list
