According to the official documentation, writelines writes a list of lines to a file. str(A) does not create a “list of lines” – obviously, when you print it to the screen – so the very first step should be to create a list-of-lines: A=[ [‘-‘, ‘A’, ‘B’, ‘C’, ‘D’, ‘E’], [‘A’, ‘0’, ‘5’, ‘6’, ‘7’, … Read more

You can use the Python replacement regex engine to do recursion and the replacement you want. Regex r”LTRIM\(RTRIM(\((?:(?>(?!LTRIM\(RTRIM\(|[()])[\S\s])+|\(|(?R))*\))\)” Replace with r”TRIM\1″ Sample import regex src=””‘ .. LTRIM(RTRIM(AB.ITEM_ID)) AS ITEM_NUMBER, .. REPLACE(LTRIM(RTRIM(NVL(AB.ITEM_SHORT_DESC,AB.ITEM_DESC))),’,’,”) AS SHORT_DESC .. LTRIM(RTRIM(AB.ITEM_ID))** AS ITEM_NUMBER,** ”’ srcnew = regex.sub(r”LTRIM\(RTRIM(\((?:(?>(?!LTRIM\(RTRIM\(|[()])[\S\s])+|\(|(?R))*\))\)”, r”TRIM\1″, src) print( srcnew ) see https://repl.it/repls/DelightfulSatisfiedCore#main.py 1 solved python replace string at 2 … Read more
You’d still use enumerate(); you didn’t show how you used it but it but it solves your issue: for index, (value,num) in enumerate(sorted_list, start=1): print(“{}.\t{:<5}\t{:>5}”.format(index, value,num)) I folded your str.ljust() and str.rjust() calls into the str.format() template; this has the added advantage that it’ll work for any value you can format, not just strings. Demo: … Read more
