I am trying to compare two text files and output the first string in the comparison file that does not match but am having difficulty since I am very new to python. Can anybody please give me a sample way to use this module.
When I try something like:
result = difflib.SequenceMatcher(None, testFile, comparisonFile)
For starters, you need to pass strings to difflib.SequenceMatcher, not files:
# Like so difflib.SequenceMatcher(None, str1, str2) # Or just read the files in difflib.SequenceMatcher(None, file1.read(), file2.read())
That'll fix your error anyway. To get the first non-matching string, I'll direct you to the wonderful world of difflib documentation.
