Hello Pythoners,I am experiencing a strange result with the pickle module when using it to write certain results to a separate file. In short, I have a program that reads a file, finds lines which satisfy some criteria, and extracts those lines, storing them in a list. I am trying to write this list to a separate file. The list of extracted lines looks like this: ATOM 1 N GLN A 1 29.872 13.384 54.754 1.00 60.40 N ATOM 2 CA GLN A 1 29.809 11.972 54.274 1.00 58.51 C ATOM 3 C GLN A 1 28.376 11.536 54.029 1.00 55.13 C The output stored from the call to the pickle.dump method, however, looks like this: (lp0 S'ATOM 1 N GLN A 1 29.872 13.384 54.754 1.00 60.40 N \r\n' p1 aS'ATOM 2 CA GLN A 1 29.809 11.972 54.274 1.00 58.51 C \r\n' p2 aS'ATOM 3 C GLN A 1 28.376 11.536 54.029 1.00 55.13 C \r\n' The code I am using to write the output to an external file goes as follows: def export_antibody_chains(): ''' EXPORT LIST OF EXTRACTED CHAINS TO FILE ''' chains_file = open(query + '_Chains', 'wb') pickle.dump(ab_chains, chains_file) # ab_chains is global chains_file.close() return Does anyone know why the strings lp0, S', aS' are showing up?
Pickle stores the type of each variable, as well as the value, and stores it in a way as to make it easy to "unpickle" it.
