Dear all,
thanx very much for the explanations. Alan helped me understand _why_ I
couldn't do what I wanted:
> No, because its just a symbol in the program (OK you could read the
> local namespace dictionary but that's messy and not to be encouraged!
> Why not just associate the dayname with the key?
and came up with practicable solution
days = {1:('friday',friday),2:('saturday',saturday).....}
for day in d
print days[day][0],days[day][1]
Jeff's solution but seems slightly more elegant and less subject to typos
(I make lots)
days = {'1': ('friday', []), '2': ('saturday', []), '3': ('sunday', [])}
d = days.keys()
d.sort()
for day in d:
name, values = days[d]
print '%s : %s' % (name, values)
And Bob came up with a really nice solution which I'm afraid I can't use
because I'm currently running Python 2.1.2 on BeOS for development so I'll
be going with Jeff's solution for the time being.
#subclass list and give it a name attribute:
class day(list):
def __init__(self, name):
self.name = name
def set(self, items):
self[:] = items
Thanx again to all!
