However I am unsure how to do this. This is what I have attempted:
def printlatex(a):
return '$', latex(a), '$'
a = 1*2
printlatex(a)
This returns the tuple `('$', 2, '$')`, which I don't want.
How would I implement the function so it returns `$2$`Mon, 29 Jan 2018 15:58:25 +0100https://ask.sagemath.org/question/40849/printing-latex/Comment by dan_fulea for <p>I am using sage and would like to implement a function that prints a variable in latex, so I can copy and paste it directly into my latex file.

https://ask.sagemath.org/question/40849/printing-latex/?answer=40858#post-id-40858Use Python string formatting.
Find more information about Python string formatting at [https://pyformat.info](pyformat.info).
For your example, you could use: `'${a}$'.format(a=2)`.
