Introductory Unix & Python Tutorial Welcome to the Unix and
Python Tutorial for BE.180! We expect for you all to attend the
tutorial sessions. The first homework assignment assumes basic
Python programming knowledge, so it is in your best interest to
come to these sessions. Upon completion of this tutorial, you
should know how to do the following: - Log in and out of UNIX -
Manipulate files and execute programs in UNIX - Start and end a
Python session - Use strings, lists and dictionaries - Write
loops (for- and while-loops) and conditional statements (if-else
if-then) - Open, modify and close a file - Compose and call
simple functions We will run Python on Athena for this tutorial.
You can log in via a Unix workstation in an Athena cluster, or
using an SSH (telnet) program on a PC/MAC. Since the computers
we will be using are running Windows, we will use the SSH client
SecureCRT. Open SecureCRT (found under Start --> Program Files)
and connect with the hostname: athena.dialup.mit.edu. Log in
with your Athena
