[Python] Delete all columns for which value repents consecutively more than 3 times

I have adf that looks like this:

date stock1 stock2 stock3 stock4 stock5 stock6 stock7 stock8 stock9 stock10
10/20 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.9
11/20 0.1 0.9 0.3 0.4 0.3 0.5 0.3 0.2 0.4 0.1
12/20 0.1 0.6 0.9 0.5 0.6 0.7 0.8 0.7 0.9 0.1
10/20 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 0.9
11/20 0.8 0.9 0.3 0.4 0.3 0.5 0.3 0.2 0.9 0.1
12/20 0.3 0.6 0.9 0.5 0.6 0.7 0.8 0.7 0.9 0.1
10/20 0.1 0.2 0.3 0.4 0.5 0.7 0.7 0.8 0.9 0.9
11/20 0.8 0.9 0.3 0.4 0.3 0.7 0.3 0.2 0.4 0.1
12/20 0.3 0.6 0.9 0.5 0.6 0.7 0.8 0.7 0.9 0.1
