where does this 'b' come from ?

if the call to b() returns a non-false value, the call to c() is useless.

You still have useless function calls.

Almost :

a = b()
if a:
  do_stuff_with_b(a)
else:
  a = c()
  if a:
    do_stuff_with_c(a)
  else:
    do_other_stuff()


Now there are probably better ways to write this, but this would require
more knowledge about your real code.
