openfile 0.0.5

A convenience function that delegates to the appropriate standard library function.

openfile is a trivial Python module that implements a single convenience function openfile(filename, mode="rt", **kwargs) wich delegates the real work to one of the following standard library functions:

gzip.open(filename, mode, **kwargs)

if the file ends with suffix .gz;

bz2.open(filename, mode, **kwargs)

if the file ends with suffix .bz2;

lzma.open(filename, mode, **kwargs)

if the file ends with suffix .xz or .lzma;

open(filename, mode, **kwargs)

if the file does not end with any suffix mentioned above.

If the filename is a single dash - then sys.stdin or sys.stdout is returned, depending on mode being r or w, respectively.
