# How to convert each pair of { and } into ( and )? [duplicate]

I am a learn-by-example person. I have no idea to change every { and } to ( and ) respectively. Could you let me know which concept in Mathematica is related to this problem so I can learn it much faster?

The objective is to convert the output of

Tuples[{{a, b, c}, {1, 2}}]

which is

{{a, 1}, {a, 2}, {b, 1}, {b, 2}, {c, 1}, {c, 2}}

to LaTeX-friendly output as follows. I have learnt TeXForm but it must be called at the last phase.

$\{(a, 1), (a, 2), (b, 1), (b, 2), (c, 1), (c, 2)\}$

Unless you have a large number of these it looks like a job for a text editor (preferably grep-friendly) or even a $\LaTeX$ macro that temporarily redefines {} (although it is also a nice hack to learn in MMA!). –  A.G. Dec 30 '13 at 19:51
