Hi Gary,
Thanks for your quick response (and sorry about mixing up b and n).
For some reason, the logic I posted seems to work ok while I'm using
the Python shell, but when used in my code, the program just hangs.
It never outputs the results. Below is the code in its entirety. Is
there a problem with my indendentation?
a = n = []
t = """
1 2
3
4 5 6
7 8 9 0
"""
d = t.split("\n")
for x in range(1,len(d)-1):
a.append(d[x].split(" "))
print a
for k in a:
n.append([int(v) for v in k])
print n
Thanks again.
Samir
