Python "While" Loops and Breaking Them

If I have two while: loops, one inside of the other, like such:

while #test :
    while #test :
        #other code
        if #test :
           break
    #other code

Will the break stop both while: loops or only the one where the if #test : is in?

Thanks for the help!

From python documentation:

break may only occur syntactically nested in a for or while loop, but not nested in a function or class definition within that loop.

It terminates the nearest enclosing loop, skipping the optional else clause if the loop has one.

"break terminates the nearest eclosing loop" - e.g. only inner while

break only stop the one where the if #test,so the other code will be exec.

A break always breaks only the loop enclosing it, so the last line of the code will be executed under the outer loop.

It would only stop the inner loop. If you wanted to break both loops, you'd have to provide another condition to break in the outer loop.
