When loops such as ‘for’ and ‘while’ are nested, the break statement in the innermost loop breaks the execution only of the inner loop, while the outer loops continue to execute.
To break out of multiple loops in Python, you can use any of the following methods.
Use Return to Break Multiple Loops
Write code containing the nested loop inside a function block and use
return instead of the
break statement. This will cause the interpreter to exit out of all the loops.
def func(): for x in range(10): for y in range(10): if y == 3: return print(y) func()
Use Loop/Else Construct to Break Multiple Loops
Write each inner loop with an
else block containing a
continue statement, followed by a
break at the end of the
[outer for] [inner for] [body] else: continue break
else block will execute only if the inner loop terminates without calling
break, which will skip the remaining of the loop (i.e.
If the inner loop breaks (i.e.
[body]), then the
else block will not execute, causing the
break of all loops.
for y in range(5): for x in range(5): print(x) if x == 3: break else: continue break
