Also, some Americans erroneously say hair's breath, and others think they mean hare's breath (which might be tiny, but diffuses quickly to theoretically infinite volume). In reality, however, they mean hair's breadth--which is quite small indeed! For instance, a hair's breadth is far smaller than a hare's breath (even at the exact moment of respiration).

Python statements not forcing whitespace is messy?
Am I the only one that thinks that python statements should force whitespace before and after them? Right now this is not enforced and for an example these statements are valid printhello fooifbarelsefoobar for(x,y)in[(1,2),(3,4)]:print(x,y) [(y)for(x,y)in[(foo,2),(bar,4)]iffooin(x)] ...and so on. I know that writing code like this really shouldn't be done but wouldn't it be a good idea to enforce the use of whitespace around statements? (I wrote a short blog post about this here http://blog.buffis.com/?p=55 but thought I would post here as well to see what other developers think) - Björn Kempén -- http://mail.python.org/mailman/listinfo/python-list

No. I don't think it should be forced, but maybe put it in PEP8 or PEP3008. Also, the only thing I find thoroughly disagreeable in all of that mess, is the run-ins involving characters.

I myself didn't even know that you could write statements like this until then, but since some students does it that means that there should be other people out there as well that does it. And I can't say that I agree about The Python philosophy being permissive, and to expect individual users to write readable Python. Python enforces proper indentation which I think is a great idea since I'm used to reading horribly indented code by others. I would love to see this extended to enforce proper whitespacing for statements. There should be one-and preferably only one-obvious way to do it. is a phrase that is usually considered pythonic, and I think that it should also apply a bit when it comes to coding conventions. - Björn Kempén -- http://mail.python.org/mailman/listinfo/python-list

Heh :) In all seriousness, sometimes, in an extremely crowded and busy expression, adding a little extra whitespace to emphasize the boundaries between sub-expressions is a good thing. And let's not forget that we can do this: complex_expression = ( ... 2*x + # double the whatzit ... 1.78**(c*3-1) + # see chapter 2 of Martelli, 2008 ... sin(radians(80)) # angle between the foo and the bar ... ) -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
