Is there a pandas Index subclass like RangeIndex that allows non-integer step sizes? Something like:
import pandas as pd
pd.RangeIndex(start=0, stop=10, step=.1) # TypeError: Wrong type <class 'float'> for value 0.1
The classes listed in the docs do not appear adequate. IntervalIndex handles arbitrary ranges but does not explicitly store a step size (which I intend to access later in my code).
You want to have a Float64Index
, there is however no parameter to define the start/stop/step.
Best is likely to use numpy.arange
:
idx = pd.Index(np.arange(0,10,0.1))
output (rounded for display):
Float64Index([ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.0, 1.0, 1.0, 1.0, 1.0,
1.0, 1.0, 1.0, 1.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0, 2.0,
2.0, 2.0, 2.0, 2.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0,
3.0, 3.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0, 4.0,
4.0, 4.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0, 5.0,
6.0, 6.0, 6.0, 6.0, 6.0, 6.0, 6.0, 6.0, 6.0, 6.0, 6.0,
7.0, 7.0, 7.0, 7.0, 7.0, 7.0, 7.0, 7.0, 7.0, 8.0, 8.0,
