Relevant development from an old friend of Sage Math who is now apparently using SymPy for some interesting stuff!
---------- Forwarded message --------- From: [email protected] <[email protected]> Date: Friday, July 14, 2023 at 10:42:05 AM UTC-4 Subject: ANN: Algebra_with_Sympy update to v0.12.0... To: Teaching with Jupyter Notebooks <[email protected]> Algebra_with_Sympy <https://gutow.github.io/Algebra_with_Sympy/> defines relations that all high school and college students would recognize as mathematical equations. They consist of a left hand side (lhs) and a right hand side (rhs) connected by the relation operator "=". In addition, it sets some convenient defaults and provides some useful controls of output formatting that may be useful even if you do not use the Equation class (see Conveniences for SymPy <https://gutow.github.io/Algebra_with_Sympy/algebra_with_sympy.html#convenience-tools-and-defaults-for-interactive-use-of-sympy> ). This tool applies operations to both sides of the equation simultaneously, just as students are taught to do when attempting to isolate (solve for) a variable. Thus the statement Equation/b yields a new equation Equation.lhs/b = Equation.rhs/b The intent is to allow using the mathematical tools in SymPy to rearrange equations and perform algebra in a stepwise fashion using as close to standard mathematical notation as possible. In this way more people can successfully perform algebraic rearrangements without stumbling over missed details such as a negative sign. Enhancements in the last two updates: - 0.12.0 (July 12, 2023) - Now defaults to interpreting numbers without decimal points as integers. This can be turned off with unset_integers_as_exact() and on with set_integers_as_exact(). When on the flag algwsym_config.numerics.integers_as_exact = True. - 0.11.0 (June 5, 2023) - Formatting of FiniteSets overridden so that the contents always pretty-print. This removes the necessity of special flags to get pretty output from solve. - Sympy solve() now works reliably with equations and outputs pretty-printed solutions. - Added option algwsym_config.output.solve_to_list = True which causes solve() to return solutions sets as Python lists. Using this option prevents pretty-printing of the solutions produced by solve(). - algwsym_config.output.show_code and algwsym_config.output.human_text now work for all sympy objects, not just Equation objects. This works in terminal, IPython terminal and Jupyter. This is achieved by hooking into the python display_hook and IPython display_formatter. - Added jupyter to requirements.txt so that virtual environment builds will include jupyter. - The way __version__ was handled could break pip install. Changed to generating the internal version during setup. This means the version is now available as algwsym_version. Feedback and feature requests welcome.
