Thiis is easier like this:

for i in a:
  if i == " ":
     print y
  else:
     y.append(i)
     m.append(y[:])   #not sure what you think this is doing!

OK, I'd suggest using while loops:

i = 0
while a[i]:
  while a[i] != " "
     m.append(a[i])
     i += 1
  y.append[m]
  i += 1

Which should give a list of lists in y

y => [[T,h,i,s],[i,s],....]

You could also use functional programming tools like list 
comprehensions I suspect.

Note that the code above is not tested, but hopefully 
its a starter.
