50 1. Documentation and usage
51 --------------------------
55 http://code.google.com/p/sympy/wiki/Documentation
57 If you don't want to read that, here is a short usage:
59 From this directory, start python and:
60 >>> from sympy import Symbol, cos
63 >>> print e.series(x, 0, 10)
64 1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10)
66 SymPy also comes with a console that is a simple wrapper around the
67 classic python console (or ipython when available) that loads the
68 sympy namespace and executes some common commands for you.
74 from this directory if SymPy is not installed or simply
78 if SymPy is installed somewhere in your PATH.
88 in the current directory. You need to have py.test installed.
91 4. How to install py.test
92 -------------------------
94 If you use Debian, just install the python-codespeak-lib. Otherwise:
96 Execute in your home directory:
98 svn co http://codespeak.net/svn/py/dist py-dist
100 This will create a "py-dist" directory in you home dir. Add this line to
103 eval `python ~/py-dist/py/env.py`
105 Now you can call "py.test" from anywhere.
110 To clean everything (thus getting the same tree as in the svn):
118 SymPy was started by Ondrej Certik in 2005, he wrote some code during the
119 summer, then he wrote some more code during the summer 2006. In February 2007,
120 Fabian Seoane joined the project and helped fixed many things, contributed
121 documentation and made it alive again. 5 students (Mateusz Paprocki, Brian
122 Jorgensen, Jason Gedge, Robert Schwarz and Chris Wu) improved SymPy incredibly
123 during the summer 2007 as part of the Google Summer of Code. Pearu Peterson
124 joined the development during the summer 2007 and he has made SymPy much more
125 competitive by rewriting the core from scratch, that has made it from 10x to
126 100x faster. Jurjen N.E. Bos has contributed pretty printing and other patches.
127 Fredrik Johansson has wrote mpmath and contributed a lot of patches. Kirill
128 Smelkov has joined the development in autumn 2007 and has improved the overall
129 quality of SymPy a lot and is currently one of the most active developers.
