Hello,
I'm wondering what the rationale is for hash comments yielding a continuation prompt (PS2) in the interactive interpreter. I'd like to put such comments in interactive examples, but the output is hard to follow:
a = 5 # and now for some multiplication
...
a * 10
50
What I would prefer can, ironically, be shown by the interactive interpreter emulator:
import code code.interact()
Python 2.3.3 (#2, May 1 2004, 06:12:12) [GCC 3.3.3 (Debian 20040401)] on linux2 Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole)
a = 5 # and now for some multiplication a * 10
50
Another apparent inconsistency is that end of line comments don't behave this way:
a = 5 a * 10 # end of line comment
50
Is there something preventing this anomaly in the interactive interpreter from being corrected?

Lack of time and effort? The parser is fairly hairy.

It's a bug -- but not easy to fix or it would have been fixed long ago. Probably the lexter could be hacked to fix this, but be careful that a change doesn't botch all the other special cases!
