One more question everybody. Say you have a class that performs a series of evaluations on several strings of peptides. Let's say for the sake of argument:
DMCDIYLLY FQPQNGQFI RHPENPNLL Heres the class: class PeptideEvaluator: def evaluate(self, peptide): peptide_name = peptide + "Rules!" result1 = self.test1(peptide, peptide_name) result2 = self.test2(peptide, peptide_name) result3 = self.test3(peptide, peptide_name) def test1(self, peptide, peptide_name): f = open(peptide_name + ".txt", "w") f.write(peptide) f.close() def test2(self, peptide, peptide_name): f = open(peptide_name + ".txt", "w") f.write(peptide) f.close() def test3(self, peptide, peptide_name): f = open(peptide_name + ".txt", "w") f.write(peptide) f.close() So, you instantiate a class called "PeptideEvaluator" and pass in each string to its "evaluate" method. Now you have to repeatedly pass the peptide and peptide_name to each function. According to what everyone has said declaring them as class variables is bad because they are not related to the state of the "PeptideEvaluator". How can I avoid having to pass the same parameters all over a class? I can';t quite seem to wrap my head around this one.
