That's not actually your code, is it? Because range(l) gives a
TypeError. In future, please copy and paste your code, don't retype it
from memory.

You are appending the same list each time, not a copy. Instead make a
copy by taking a slice from the current position to the end of
the list:
for i in range(len(l)):
b.append(l[i:])
print b
will do what you want.
