Best GUI for sympy with Latex formatting... how do I force Latex printing of a function ?

[linux guy]

Hi.

I'm working on a big math problem.   Sympy is saving my butt.  Many thanks for this excellent tool.  Open source rules !

What is the best (gui) environment to run sympy in ?  

I love seeing equations formatted in Latex so that I can be sure the code I am writing in python is matching what I want the equation to be.  It's also great to copy and paste Latex equations into my documentation, rather than a line of python.

I've been using the Jupyter notebook, but I don't usually use an interactive shell.  I find Jupyter notebook to be kind of clumsy.

I develop in Fedora, so I am familiar with Spyder, Eclipse, Kwrite, Konsole, etc.  I prefer to write code and run it.  If I do that, how do I force sympy to output symbols in Latext (to a console) ?

Also, if I run this code in Jupyter, it outputs the latext equation for width in Latex.

width = r*cos(theta)*sin(phi)
width

But if I run this code in Jupyter cell, it only outputs phi, not width

width = r*cos(theta)*sin(phi)
width

phi = symbols('phi')
phi

Why ?

And if I run print(latex(width)) it will output "width" in Latex, not the equation that is assigned to width.

How do I get sympy to output the equation of width in Latex ?

Better yet, how do I get sympy to output "width =... equation..." in Latex ?

Thank you.

One other thing... I see that sympy appears to be used in Octave !  Personally, I'd rather work in Python than Octave, but I'd rather work in Octave than Jupyter.  Is there a way to get latex output from sympy in Octave ?

Maybe I just don't know how to use Jupyter very well...

Lets say that I have 30 code cells in Jupyter, each with a few lines of python in them.   And I'm happy with how everything runs.   Is there an easy way to export just the code cells to a file, without manually cutting and pasting them individually ?

There is file->download as -> Python.py, but it puts blank lines between the code lines and includes the output lines.  Kind of a pain... If it exported cleanly, I could do all my math development in a Jupyter notebook and then export the code to a file when I was done.   This way if I make a change to the notebook I have to re export the code and then spend time cleaning it up.   Write a script ?   Am I the only one that thinks this way ?

Other things I don't like about Jupyter include the lack of key shortcuts for simple things like deleting a cell... am I missing something ?

Jupyter is what I'd generally recommend. Jypyter lab is newer than the
notebook so I would suggest using that.

Another thing you can try is Spyder, which supports SymPy LaTeX output
and is better if you are trying to edit .py files.

You could use the qtconsole version of IPython. I think that may be what Spyder defaults to.
