sympy-pipes 0.1.0

A collection of Pipe definitions for working with sympy.

SymPy Pipe

This package provides a subset of the SymPy expression manipulation functionality as pipes (using the Pipe package). This facilitates their usage (especially when doing interactive manipulation in Jupyter). They all act on single expressions or, most useful, on iterables of expressions (returning a respective generator).

The pipes have the same interface as the original SymPy functions/methods, with the exception of the first parameter being the expression or expression iterable to work on (filled by the | operator).

Examples

All examples depend on the following initialization code:

from sympy import Symbol
x = Symbol("x")
y = Symbol("y")

simplify

from sympy_pipes import simplify
x + x | simplify
[x + x, 2 * x + x] | simplify

subs

from sympy_pipes import subs
x | subs(x, y)
[x, 2 * x] | subs({x: y})

limit

from sympy_pipes import limit
x**2 | limit(x, 1)
[x**2, 2 * x] | limit(x, y)

diff

from sympy_pipes import diff
x**2 | diff(x)
[x**2, 2 * x] | diff(x, 2)

integrate

from sympy_pipes import integrate
x | integrate(x)
[x, 2 * x] | integrate((x, 1, 2))

display

To pretty print iterables of expressions in Jupyter environments. This function is only available, if IPython is installed in the environment! The display pipe returns its input, so it can be used to output intermediate results.

from sympy_pipes import display, subs
x | display | subs(x, y) | display
[x, 2 * x] | display | subs(x, y) | display
