Yes I know there are many questions like this.
This question is about a specific behavior:
import pandas as pd
x = [
0,0,0,0,
1,1,1,
2,2,2,
3,3,3
]
print pd.qcut(x, 4)
# ValueError: Bin edges must be unique: array([0, 0, 1, 2, 3]).
I had assumed qcut would produce edges (0,1], (1,2], (2,3], (3, 3), which would bin the items how I visually organized them. This obviously has to something to do with left-inclusivity and right-exclusivity but intuitively it feels like x can be discretized into four parts.
Does anyone have a sense of what I'm missing?
