[New-bugs-announce] [issue46302] IndexError inside list comprehension + workaround

[Pierre Fortin]

New submission from Pierre Fortin <pf at pfortin.com>:

var = "u2"
var.strip()[0] 
Works as expected, except that it returns IndexError (instead of "u") if used in a list comprehension -- at least, that's where I found it.  Attached example script illustrates the issue.
Call it with "mytest N" where N is 1 (fails), 2 (works), 3 (fails).
mytest 1 -- KeyError expected; this was due to infile design change
            adding a digit to previously single char code
mytest 2 -- workaround to actual issue in next test
mytest 3 -- adding [0] fails when used in list comprehension
