I got to line 22, saw the bare except, and promptly gave up.
Oh, keep going, Mark. It gets better.
def readstrfile(file):
try:
data=open(file,"r").read()
except:
return 0
return data
def start():
psource=readstrfile(infile)
if psource==0:
print ("Can't open file",infile)
exit(0)
So, if any exception happens during the reading of the file, it gets
squashed, and 0 is returned - which results in a generic message being
printed, and the program terminating, with return value 0. Awesome!
I don't have a clue about exceptions, but why wouldn't read errors be
picked up by the same except: block?
But I've anyway sprinkled one or two more try/excepts in there and put
some actual exception codes in. However, this readstrfile() is just
there to load the file into memory and avoid having a 200,000-line
string in the program.
