So some files were in ASCII-based encoding (windows-1251) but the others in utf-8. Of course you can declare that support for such extensions would be heretical and no EBCDIC source file would be True Python Source and no EBCDIC implementation would be a True Python Implementation, but I don't really care. file section. It defines metadata structure. This made it possible the implement and test a new set of extracts in a few days. The international version (which includes the lib/charsets. Another option for working out the encoding is to use libmagic (which is the code behind the file command). open the file with 'U', Python will return lines w/o the \r character whether or not they started with it, equally well on both unix and Microsoft systems. Each codec has to define four interfaces to make it usable as codec in Python: stateless encoder, stateless decoder, stream reader and stream writer. The load and reconciliation processes were implemented as object-oriented, data driven PERL scripts. As we noted above, the EBCDIC file is UTF-8 encoded, so we read it using this encoding. The filename is specified by the first method argument, and the charset of the text data is specified by the 2nd method argument. If the attribute exists, its value is called with no arguments just before interactive mode is started. If you develop software, be sure you recognise Antipatterns just as well as Patterns.
