Re: Loop with else clause

Wow, you dug deep. My example was the reverse of the "toy example"'s you mention as I find that often code becomes much clearer if you order it such that specific cases, sanity checking and exceptions go first, and then the default case at the end. So my general suggestion would be to handle yo

Further to our discussion of how to improve a code review's discovery of the mistaken handling of a for...else... construct:- Yesterday was a national holiday, but today gave some opportunity to research. Way back in 2009 there was spirited discussion over on the Python Ideas list (warning, e

RE: Loop with else clause

The topic is how to deal with a python loop that may not be run if you want something else to happen in that case. Multiple solutions are presented along with this request: > Is there another, more pythonic, approach to conditional (for/while) > loop processing? Has anyone considered looking at

Re: Loop with else clause

I don't know if it is very Pythonic, but I would do something like if no_oscar_nominees: print ("Sorry ...") else: print_list_of_oscar_nominees() And yes, that for/else construct can be confusing. Adriaan. >>> On 5-2-2019 at 5:29, DL Neil wrote: > What is the pythonic way to handl

Loop with else clause

What is the pythonic way to handle the situation where if a condition exists the loop should be executed, but if it does not something else should be done? Why am I asking? Today's code review included a for...else structure. I've rarely seen such a thing, and even knowing it exists, cannot r
