'How to swap signal without iterrows or itertuples
I'm struglling with pandas, I'm trying to define the B col as true after A col return 1, then return false when A col return 1 again.
Any ideas how to make this happen without iterrows or itertuples?
A B
0 0 false
1 0 false
2 1 true
3 0 true
4 0 true
5 1 true
6 0 false
7 0 false
