[Tutor] infix to postfix eval

[Laura Creighton]

Hi Anish.

I wanted to let you know something I found out last week.
Even when you select plain text email, gmail will mangle
any lines of text starting with one or more '>' marks.

So when you write:

   >>> import string
   >>> string.uppercase
   'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
   >>> string.digits
   '0123456789'
   >>>

except all flush with the left margin, gmail thinks that it would be a
great idea to reflow this text, as if this was a quoted text from
somebody else.

Until we can get Google to stop doing this, the work-around is to
indent your output from the python console, or change your python
console prompt to py> or something.  The values of the prompts are
stored in sys.ps1 and sys.ps2 and you can change them to whatever you
like.

Just thought you would like to know,
Laura
