Dino is absolutely right. In our new conversion rules, there is no implicit conversion between integer types (both standard Python types - int and bigint, and CLR integer types - byte, sbyte, short, ushort, long, ulong, uint, decimal) and char. Char is in Python pretty much interchangeable with one-character string and we tried to find the right balance for conversions that are implicit and those which require explicit 'cast'. Consider for example CPython's:
>>> range('a') Traceback (most recent call last): File "<stdin>", line 1, in ? TypeError: range() integer end argument expected, got str. You can still do int("1") or int(Char.Parse('a')), both explicit conversions. Hope this helps.

I think this is probably due to some changes w/ method dispatch (we'll no longer convert from char to int?). I'll have to ask around to see if that's part of the design or not. As a work around you can do: chr(ord(a.KeyChar)) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jörgen Stenarson Sent: Thursday, July 13, 2006 3:17 PM To: Discussion of IronPython Subject: [IronPython] Bug in beta9? Hi I have hit a change in the behaviour that results in an exception. Is this behaviour expected? My workaround for now is to change chr to str. /Jörgen file(tipy.py) used in test: import System readkey=System.Console.ReadKey print "Press a key" a=readkey(True) print chr(a.KeyChar) Test with beta8: >c:\IronPython-1.0-Beta8\IronPythonConsole.exe tipy.py Press a key d Test with beta9: >c:\IronPython-1.0-Beta9\ipy -i tipy.py Press a key Traceback (most recent >call last): File C:\python\pyreadline_branch\pyreadline\console\tipy.py, line 8, in Initialize File , line 0, in Chr##75 TypeError: Cannot convert Char(d) to Int32 _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com _______________________________________________ users mailing list users@lists.ironpython.com http://lists.ironpython.com/listinfo.cgi/users-ironpython.com
