[Python-ideas] Make for/while loops nameable.

Hi, sometimes I do nested loops and I want to break specific loop, outer/inner etc. I need to do an ugly thing with for..else and it's annoying. It'd be nice if we could do so: for i in range(10) as loop_i: for j in range(i, i + 10) as loop_j: if i + j == 9: break loop_i o

[Python-ideas] Re: Make for/while loops nameable.

Greetings list, I wonder if the issue should be named as: introduce absolute break in Python as if you have 5 nested loops (which you probably should not), breaking loop_i won't do anything Kind Regards, Abdur-Rahmaan Janhangeer about | blog

I personally am +1 for something like this. What about for use with `continue` as well? e.g. > for i in range(10) as i_loop: > for j in range(i, i + 10) as j_loop: > if i + j == 9: > continue i_loop which will break out of j_loop and go to the next i (as if the `continue

Hi Jonatan Please consider for a in aaa: for b in bbb: if condition(a, b): break KEYWORD: break where KEYWORD is like else, but with the opposite semantics. I think this does exactly what you asked for, in your example. In July this year

[Python-ideas] Re: Make for/while loops nameable.

Hi everyone, I'm not in favor of naming loops, as this looks too much like variable. (What happens when variable names and loop names names collide ? Does the loop identifier bind to anything ?) On the other hand, I like the feature very much, and I have thought about it in the past. My take

[Python-ideas] Question about binary dunder deferring logic

Hi all, I just sniped myself wondering about how correct dispatching for dunders works for independently derived subclasses. This is an extreme corner case where two subclasses may not know about each other, and further cannot establish a hierarch: class A(int): pass class B(int

[Python-ideas] Re: Make for/while loops nameable.

Why not start at break 0 not break 1, similar to sequences starting at index 0? Maybe if break alone without integer, it breaks from the loop it is at similar to the behavior we have right now in Python. E.g., for matrix in matrix_array : # Index 0 for x in range(0,10) : # Index 1
