Is there an easier way to break out of nested loops than throwing an exception? (In Perl, you can give labels to each loop and at least continue an outer loop.)
for x in range(10): for y in range(10): print x*y if x*y > 50: "break both loops" I.e., is there a nicer way than:
class BreakIt(Exception): pass try: for x in range(10): for y in range(10): print x*y if x*y > 50: raise BreakIt except BreakIt: pass

Using break in a nested loop In a nested loop, a break statement only stops the loop it is placed in. Therefore, if a break is placed in the inner loop, the outer loop still continues. However, if the break is placed in the outer loop, all of the looping stops.
Originally Answered: How can I avoid nested "for loop" for optimize my code? Sort the array first. Then run once over it and count consecutive elements. For each count larger than 1, compute count-choose-2 and sum them up.
for x in xrange(10): for y in xrange(10): print x*y if x*y > 50: break else: continue # only executed if the inner loop did NOT break break # only executed if the inner loop DID break The same works for deeper loops:
for x in xrange(10): for y in xrange(10): for z in xrange(10): print x,y,z if x*y*z == 30: break else: continue break else: continue break If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
