The Python symbol calculates the Swiss army knife--sympy

Quick to use

In the Anaconda integrated Environment Spyder, you can
Preferences > IPython Console > Advanced Settings > Use symbolic Math
To activate the IPython ' s Symbolic PYthon (sympy) module

This module allows you Spyder to Latex render a very beautiful mathematical expression in style, and IPython automatically imports some basic symbol objects at the terminal when it is launched.

>>> fromimport division>>> fromimport *>>> x, y, z, t = symbols(‘x y z t‘)>>> k, m, n = symbols(‘k m n‘, integer=True)>>> f, g, h = symbols(‘f g h‘, cls=Function)

Enter the following command at the terminal

>>> fromimport *>>> x = symbols(‘x‘)>>> a = Integral(cos(x)*exp(x), x)>>> Eq(a, a.doit())

The terminal displays the results as follows:

You can see the result of the output is very beautiful!

More instance codes and instructional documents can be found on the official website

It's interesting to have an online sympy Shell

Enter an expression in the intended Web page, and then get the returned results, such as entering

>>> expr = x**2 + x*y>>> srepr(expr)>>> expr = (x + y)**5>>> expand(expr)

The returned results can be seen in the SymPy Live Shell on the right, very nice!
