Re: [Python-ideas] Ternary operators in list comprehensions

Putting it another way, your example doesn't make sense.  How would you parenthesise it to make it clearer?     [ (x for x  in a if x & 1) else 'even']     You have an "else" without an "if".     [ x for x  in (a if x & 1 else 'even')]     Using x before it has been defined, at least in

>>> a = [1,2,3] >>> [x if x & 1 else 'even' for x in a] [1, 'even', 3] You're mixing the if clause of the list comprehension up with a ternary expresssion. There's no "else" in the list comprehension if clause. Paul On 5 October 2017 at 16:40, Jason H wrote: a = [1,2,3]

Re: [Python-ideas] Ternary operators in list comprehensions

[x if x & 1 else 'even' for x in a] An `if` at the end of the comprehension means a condition on whether to include the value. Also, this question would have been better asked on python-list. 2017-10-05 8:40 GMT-07:00 Jason H : > >>> a = [1,2,3] > >>> [ x for x in a if x & 1] >

Thanks, Nick! I'll let this sink in today and give it a shot tomorrow. Have a great weekend, --diana > * Switch to your suggested "set-of-strings" API at the Python level, > with the Python level integer interface retained only for backwards > compatibility > * Keep the current integer-based
