48 1. Documentation and usage
49 --------------------------
53 http://code.google.com/p/sympy/wiki/Documentation
55 If you don't want to read that, here is a short usage:
57 From this directory, start python and:
58 >>> from sympy import Symbol, cos
61 >>> print e.series(x, 0, 10)
62 1 + (1/2)*x**2 + (5/24)*x**4 + (61/720)*x**6 + (277/8064)*x**8 + O(x**10)
64 SymPy also comes with a console that is a simple wrapper around the
65 classic python console (or ipython when available) that loads the
66 sympy namespace and executes some common commands for you.
72 from this directory if SymPy is not installed or simply
76 if SymPy is installed somewhere in your PATH.
86 in the current directory. You need to have py.test installed.
89 4. How to install py.test
90 -------------------------
92 If you use Debian, just install the python-codespeak-lib. Otherwise:
94 Execute in your home directory:
96 svn co http://codespeak.net/svn/py/dist py-dist
98 This will create a "py-dist" directory in you home dir. Add this line to
101 eval `python ~/py-dist/py/env.py`
103 Now you can call "py.test" from anywhere.
108 To clean everything (thus getting the same tree as in the svn):
116 SymPy was started by Ondrej Certik in 2005, he wrote some code during the
117 summer, then he wrote some more code during the summer 2006. In February 2007,
118 Fabian Seoane joined the project and helped fixed many things, contributed
119 documentation and made it alive again. 5 students (Mateusz Paprocki, Brian
120 Jorgensen, Jason Gedge, Robert Schwarz and Chris Wu) improved SymPy incredibly
121 during the summer 2007 as part of the Google Summer of Code. Pearu Peterson
122 joined the development during the summer 2007 and he has made SymPy much more
123 competitive by rewriting the core from scratch, that has made it from 10x to
124 100x faster. Jurjen N.E. Bos has contributed pretty printing and other patches.
125 Fredrik Johansson has wrote mpmath and contributed a lot of patches. Kirill
126 Smelkov has joined the development in autumn 2007 and has improved the overall
127 quality of SymPy a lot and is currently one of the most active developers.
