Hi list,
I've recently developed a basic python program which needs to store
some data in a file (e.g. a directory path).
What the program needs is a dictionary containing the data, so I used
the pickle module to store the dictionary in a file and read it back
when the program is launched.
I wanted to know which is the common pattern in python programming in
this case, because the way I've choosen only lets the user configure
the data via a GUI (the file is somehow compiled). Is it better to
store the data in a text file and then parse it and construct a
dictionary? Or is there e third way?
Following the Unix philosophy (Store data in flat text file), it is
much better to dump the dictionary into a plain text file, but pickling
is so damn easy. If you have the time and space to do it, you should
make a dumper and parser, if not, there is no real problem with using
pickled format as far as I'm aware (especially if you strictly don't
want someone to manually modify the file).
The only potential problem, I could think of, is whether pickled data is
cross-version compatible.
