Bug in cPickle with packages and 'object' inherited class

Say you have this structure: pna/ __init__.py model.py __init__.py is empty. model.py is: import cPickle as pickle class A(object): pass def serialize(): pickle.dump(A(), open('temp.dat', 'wb')) Now open a python interpreter on the root directory of that structure and type

Re: first, second, etc line of text file

Thanks all! I think I will stick to my original method because the files can be quite large and without reading the whole file into memory probably enumerate( open( textfile ) ) is the only way to access an arbitrary Nth line. -- http://mail.python.org/mailman/listinfo/python-list

Re: Why PHP is so much more popular for web-development

I'm an ex-PHP programmer (well, I still have to use some PHP at work, but I don't tell anyone that at parties) who now uses Python or Lisp wherever possible for web development. I can tell you exactly why PHP is so popular: it acts as an extension of HTML and is syntactically similar to Perl. PHP

Re: first, second, etc line of text file

Depending on the size of your file, you can just use file.readlines. Note that file.readlines is going to read the entire file into memory, so don't use it on your plain-text version of War and Peace. >>> f = open("/etc/passwd") >>> lines = f.readlines() >>> lines[5] '# lookupd DirectoryServices

Re: first, second, etc line of text file

Files should be iterable on their own: filehandle = open('/path/to/foo.txt') for line in filehandle: # do something... But you could also do a generic lines = filehandle.readlines(), which returns a list of all lines in the file, but that's a bit memory hungry. -- http://mail.python.org/mai
