Consider:
def read_default_from_config(cfg_file):
#pseudocode
if not_specified_in(cfg_file):
return None
return read_value_from(cfg_file)
a = None
b = read_default_from_config("1.cfg")
c = read_default_from_config("2.cfg")
print a or b or c
Now, what happens when the user puts a default of 0 in 1.cfg? This was
my intended point.
Cheers,
Chris
