Python - `break` out of all loops
break, for-loop, loops, python, python-2.7
Solution
You should put your loops inside a function and then return:
def myfunc():
for i in range(1, 1001):
for i2 in range(i, 1001):
for i3 in range(i2, 1001):
if i*i + i2*i2 == i3*i3 and i + i2 + i3 == 1000:
print i*i2*i3
return # Exit the function (and stop all of the loops)
myfunc() # Call the function
Using `return` immediately exits the enclosing function. In the process, all of the loops will be stopped.
Problem
I am using multiple nested `for` loops. In the last loop there is an `if` statement. When evaluated to `True` all the `for` loops should stop, but that does not happen. It only `break`s out of the innermost `for` loop, and than it keeps on going. I need all loops to come to a stop if the `break` statement is encountered. My code: ``` for i in range(1, 1001): for i2 in range(i, 1001): for i3 in range(i2, 1001): if i*i + i2*i2 == i3*i3 and i + i2 + i3 == 1000: print i*i2*i3 break ```
