How to modify the value of a Yolo .txt file in python

I want to modify a folder with .txt files

The txt file look like this:

3 0.695312 0.523958 0.068750 0.052083  3 0.846875 0.757292 0.071875 0.031250  3 0.830469 0.719792 0.067187 0.035417  

My idea is take all the .txt files and change inline the first number.

Output example:

2 0.695312 0.523958 0.068750 0.052083  2 0.846875 0.757292 0.071875 0.031250  2 0.830469 0.719792 0.067187 0.035417  

Can you help me?
