| Python
for CMPUT 499/510 |
The ambition of this web
page is to provide all information about using python that needs to be
known by students in the Reinforcement
Learning for Artificial Intelligence
course at the University of
Alberta. In particular, we describe how to get
Python to print "hello" in various ways on various machines.
1) interactive use
In your shell window type:
python
(it will respond with the >>> prompt)
>>> print "hello"
hello
>>> (use cntl-D to exit)
2) from a file
edit h.py, put print "hello" as first line
In your shell window type:
python h.py or
python < h.py
hello
(output)
3) interactive loading a file
edit h.py, put print "hello" as first line
In your shell window type:
python
>>> import
h
(note that the .py is not needed here)
hello
>>>
There are other options: see the man pages for details.
Python is available on:
1) the Grad linux boxes
(use python2.3 and idle2.3 to get version 2.3. The regular
python and idle
commands will start up version 2.2)
2) the Solaris boxes Update: Quick fix here
3) the OS X Macintosh computers in SUB (the student union
building). These are located in the basement, more or less across
the
hall from the University Microstore/Bookstore. Follow the
instructions for logging on with your CNS id and password, then select
the terminal application from the dock (it looks like this:
). Then
you can say "python" to the unix prompt, etc. Currently we are
double-checking that this works...
4) your home machine if you want to use it. Go to www.python.org.
