### Printing latex

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. 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 `$2$`
