Find number betwen commans

Toze Cerdeira

I have this file:

[p2,115,0,4,] Steel Drums
[p2,116,0,4,] Woodblock
[p2,117,0,4,] Taiko
[p2,119,10,4,] Sine Perc.
[p2,118,0,4,] Melo. Tom 1
[p2,118,18,4,] Jungle SD

How to subtract “1” to the first value between comans

,115,
,116,
,117,
,118,
,118,
etc

Thanks

You would have to script a solution to that.
A similar discussion that would show you how to do it is HERE.

In your case your “find” expression could be: p2,(\d+), and you could replace with 'p2,' + str(int(m.group(1)) - 1) + ',' or something close to that; there are a few different ways to write these expressions.
