Here is a solution using plac (http://pypi.python.org/pypi/plac):
$ echo c2f.py
import plac
class Converter(object):
commands = ['celsius_to_fahrenheit', 'fahrenheit_to_celsius']
@plac.annotations(t='convert Celsius to Fahrenheit')
def celsius_to_fahrenheit(self, t):
return round(32 + float(t) * 9/5)
@plac.annotations(t='convert Fahrenheit to Celsius')
def fahrenheit_to_celsius(self, t):
return round((float(t) - 32) * 5 / 9.0)
if __name__ == '__main__':
import plac; plac.Interpreter.call(Converter)
Here is an example of non-interactive usage:
$ python c2f.py fahrenheit_to_celsius 212
100.0
$ python c2f.py celsius_to_fahrenheit 100
212.0
Here is an example of interactive usage:$ python c2f.py -i
i> celsius_to_fahrenheit 100
212.0
i> celsius_to_fahrenheit 0
32.0
i> fahrenheit_to_celsius 32
0.0
i> fahrenheit_to_celsius 212
100.0
