together print latex formula and value of variable

[Sandor Szabo]

Hi,

In Jupyter Notebook the code

print( "f(x,x^2)=",  f(x, x**2) )

gives the output

f(x,x^2)= 1/2

Instead of   f(x,x^2) I would like to obtain

           2

  f(x, x ).

How does it possible to put LaTeX code into print command and print the nice

output and the value of a calculated variable?

I tried Eq( a, b), but I'm not satisfied with it.

There is the extension Py2Tex, but I don't know if it still works with the current Jupyter Notebooks since it was last updated four years ago.  Repository for extension.

Thanks for the suggestion. I try to find an alternate solution, maybe asking in other forum.

If you are happy with writing the Latex string yourself, you can simply use the latex display capability of Jupyter / IPython (combined with normal python string formatting to include variable values etc), e.g. with

from IPython.display import Latex, display_latex

x = 3.65

display_latex("$x^2 = %g$"%x, raw=True)

or, equivalently, with 

display(Latex("$x^2 = %g$"%x))

If the Latex object is the last line in your cell, it will be displayed automatically. If you are not using ipython, but a different kernel, you have to find out how to produce objects with a LaTeX representation (e.g., Julia has https://github.com/stevengj/LaTeXStrings.jl).

Best,

Johannes

Thanks. Your solution is the easiest and simplest.
(In the meantime I found some module which hopefully could do the same task, but I will use your solution.)

Best,

Sandor
