I need to generate a list 2d matrix of the kind ...

except its dimensions need to be 7 x 75. I thought I had it sorted with
map2 = [ [''] *7 ] *75
until the coding screwed up & I realised I had 75 references to the same
list :-(
Try:
map2 = [['']*7 for n in range(75)]
The list comprehension will execute ['']*7 each iteration, creating a
new list instead of just creating new references to the same list.
Oh PS
Is there a more elegant solution to
if string == 'sun' or string == 'mon' or string == 'tue' or string ==
'wed' or string == 'thu' or string == 'fri' or string == 'sat':
Try:
if string in ['sun', 'mon', 'tue', 'wed', 'thu', 'fri', 'sat']:
(Or perhaps look into using the datetime module, depending on how
detailed your needs are.)
