Finding differences between strings

Question

I have the following function that gets a source and a modified strings, and bolds the changed words in it.

def appendBoldChanges(s1, s2):
    \"Adds &l         


        

Answer 1

A small upgrade tp @fraxel answer that returns 2 outputs - the original and the new version with marked changes. I also change the one-liner to a more readable version in my opinion

def show_diff(text, n_text):
    seqm = difflib.SequenceMatcher(None, text, n_text)
    output_orig = []
    output_new = []
    for opcode, a0, a1, b0, b1 in seqm.get_opcodes():
        orig_seq = seqm.a[a0:a1]
        new_seq = seqm.b[b0:b1]
        if opcode == 'equal':
            output_orig.append(orig_seq)
            output_new.append(orig_seq)
        elif opcode == 'insert':
            output_new.append("{}".format(new_seq))
        elif opcode == 'delete':
            output_orig.append("{}".format(orig_seq))
        elif opcode == 'replace':
            output_new.append("{}".format(new_seq))
            output_orig.append("{}".format(orig_seq))
        else:
            print('Error')
    return ''.join(output_orig), ''.join(output_new)
