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.
