i need help on 2 topics. 1) can someone please tell me what sys is doing, and why its using weird indexing?
if __name__ == "__main__": A_Class(*sys.argv[1:4]).A_Class_Method() is sys able to call methods? if so why does it need indexing if it uses * . ------------------------------------------------------------------------------------------------------ 2) also i need help with zipfiles. these 2 functions are related in the same class. def __init__(self): self.zipping_directory = "unzipped-{}".format(filename) def _full_filename(self, filename): return os.path.join(self.zipping_directory, filename) def zip_files(self): file = zipfile.ZipFile(self.filename, 'w') for filename in os.listdir(self.zipping_directory): file.write(self._full_filename(filename), filename) the main thing i need help with is the last line. the zip file is writing to a file but why does it use the same argument twice? the for loop above that line returns the file from the zipping directory, which is the 2nd argument on file.write? But the 1st argument is using that same file because that is the file returned from the def _full_filename(self, filename): method. so please can someone tell me why it uses the same file argument twice in its write method? thanks for your time
