It's so ANNOYING to break out of nested loops.

Auxiliary variables, conditional statements, non-linear paths through your code...

It's a mess!

But if you extract the looping logic to a generator, you get:

- less indentation ✨
- a flat loop you can easily break out of ✨

Diagram showing the trick in action.

Code before simplification:

done = False
for n in range(1, len(switches) + 1):
for group in combinations(switches, n):
state = simplify(group)
if state == target:
print("found!")
done = True
break
if done:
break

Code after simplification:

def groups_of_switches(switches):
for n in range(1, len(switches) + 1):
for group in combinations(switches, n):
yield group

for group in groups_of_switches(switches):
state = simplify(group)
if state == target:
print("found!")
break
