| I know that overall Global variables are bad idea, however,
| I have a situation where on on initialisation of a class, I
| need to read in two files and then populate two lists.
| The lists need to would appear to need to be outwith the
| class I am working with and global.
| Can anyone give good examples of this?
Well, in simple terms this *sounds* like what
you're trying to do (not attempting any more
Python approach at this juncture):
l1 = 
l2 = 
def __init__ (self, filename1, filename2):
l1.extend (open (filename1).readlines ())
l2.extend (open (filename2).readlines ())
if __name__ == '__main__':
open ("test1.txt", "w").write ("hello\nworld\n")
open ("test2.txt", "w").write ("goodbye\nworld\n")
x = X ("test1.txt", "test2.txt")
Obviously this code doesn't do anything terribly
useful, but I wanted to see if it was more-or-less
what you had in mind?
