Converting from a string to boolean in Python

Really, you just compare the string to whatever you expect to accept as representing true, so you can do this:

s == 'True'

Or to checks against a whole bunch of values:

s.lower() in ['true', '1', 't', 'y', 'yes', 'yeah', 'yup', 'certainly', 'uh-huh']

Be cautious when using the following:

>>> bool("foo")
>>> bool("")

Empty strings evaluate to False, but everything else evaluates to True. So this should not be used for any kind of parsing purposes.
