Can some one help me with this error? Error Value: You are not allowed to access 'SequenceMatcher' in this context Does this say that I cannot use difflib in python script? here is the snippet of code: # find the record that matches the best s = difflib.SequenceMatcher(None, name_first, R['name_first']) v1 = round(s.ratio(), 3) I am trying to determine if a record in the database is close to the data submitted by the user. An example is the address 914 Lois lane and 914 Lois LN With SequenceMatcher this returns a 97% probability that these two are the same. Thanks Gene
