I would like the element-wise logical OR operator. I know "or" itself is not what I am looking for.
For AND I want to use & as explained here. For NOT I want to use np.invert() as explained here. So what is the equivalent for OR?
The corresponding operator is |:
df[(df < 3) | (df == 5)]
would elementwise check if value is less than 3 or equal to 5.
