This will probably seem to obvious to mention to many, but it took me a few years to realise that you could replicate the "BREAK XYZ" from languages of yesteryear:
FOR I = 1 TO 10
FOR J = 1 TO 10
FOR K = 1 TO 10
DOSOMETHING I, J, K
REM Breaks out of the middle loop, continues next I iteration
IF SOMECONDITION(I, J, K) THEN BREAK J
NEXT K
NEXT J
NEXT I
in modern languages by refactoring the loop you want to break out of into a function and using return instead:
def inner_loops(i):
for j in range(10):
for k in range(10):
do_something(i, j, k)
if some_condition(i, j, k):
return
def fn():
for i in range(10):
inner_loops(i)
