I'm trying to modify a find/replace script that I previously got help with here on Daniweb. The script below iterates through a file A and makes replacements defined in a csv file B. My original goal was to change any line in file A containing a search string (in whole or as a substring) defined in file B. File B contains both the search string and the string it should be changed into.
Example file A
Example File B (substring,new form)
But now I'd like to only make the change if there is an exact match. So the search string "ippy" should no longer cause "slippy" to change.
I tried changing "if search >= 1" to "if search == 1", but that makes zero changes.
#original find_replace.py import string, sys, os import csv myOut = open('out_replace.txt', 'w') myFile = open("test_verb_list.txt","r") data = myFile.read() myFile.close() changes = csv.reader(open('test_old_new.csv', 'rb')) for line in data: for old, new in changes: search = string.find(data,old) if search >= 1: data = data.replace(old, new) print>>myOut, data myOut.close()
