Python for Scientists
Introduction
Getting Started on BlueCrystal Phase-2
After you have logged in, type the following at the command line:
module add languages/python-2.7.2.0 python
This should start up an interactive python session:
Python 2.7.2 (default, Aug 25 2011, 10:51:03) [GCC 4.3.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>>
where we can type commands at the >>> prompt.
Python as a Calculator
Let's try a few commands out. If you type:
>>> print "Hello!"
you'll get:
Hello!
If you try:
>>> print 5 + 9
you'll get:
14
And here is a copy of a session containing a few more commands:
>>> five = 5
>>> neuf = 9
>>> print five + neuf
14
>>> def say_hello():
... print "Hello, world!"
... # hit return here
>>> say_hello()
Hello, world!
