I'm working with Pandas, but I have a question about how to change equivalent values. I want to work with binary values in the "class" column so I have 1 and I want 2 and 3 to be changed to 0. Ah! And I don't just have these lines, I have 70 in total! How do I do it?
id class col2 col3
0 1 2 0
1 1 1 1
2 1 9 9
3 2 8 4
4 2 7 2
5 2 4 3
6 2 7 2
7 3 1 4
8 3 2 8
9 3 3 9
I want this result:
id class col2 col3
0 1 2 0
1 1 1 1
2 1 9 9
3 0 8 4
4 0 7 2
5 0 4 3
6 0 7 2
7 0 1 4
8 0 2 8
9 0 3 9
