Some useful Python one-liners taken from
All modules listed are part of the standard library and should work with Python 2.6+
How to use:
$ python -m [module] [arguments]

cgi, dumps a bunch of information as HTML to stdout
CGIHTTPRequestHandler - same as SimpleHTTPServer except via the CGIHTTPRequestHandler: it will executes scripts it recognizes as CGI, instead of just sending them over (has not survived the transition to Python 3)
compileall - compiles a tree of Python files to bytecode, has a bunch of options. Does not compile to stripped files (pyo)
cProfiler - runs the provided script file (argument) under cProfiler
dis disassembles a python script
doctest - runs doctests on the provided files (which can be python scripts or doctest files)
encodings.rot_13 - rot13 encodes stdin to stdout (has not survived the transition to Python 3)
