QUESTION 1

[C:Python26/Scripts]
|16>

[C:Python26/Scripts]
|17>2/3
1[17] 0.66666666666666663

[C:Python26/Scripts]
|18>

What is the 1 that begins   1[17] 0.66666666666666663 ?

QUESTION 2.

I'd like IPython to start with mpmath already imported. In
ipy_user_conf.py I tried putting the 3 lines

from mpmath import *
mp.dps=25
mp.pretty=True

inside main() , and then above  def main() ,  but they are ignored.
What's the correct way to do this?

Of course, entering the line
from mpmath import *;mp.dps=50;mp.pretty=True
at the IPython prompt works.

QUESTION 3

Why do some lines go above  the line  "def main()"  and some inside  main()?

Thanks,

Dick Moores
