Pandas' equivalent of resample for integer index

Question

I\'m looking for a pandas equivalent of the resample method for a dataframe whose isn\'t a DatetimeIndex but an array of integers, or maybe even fl

Answer 1

Alternative, this is one thing that can be done

def resample(df, rule, how=None, **kwargs):
    import pandas as pd
    if how==None:
        import numpy as np
        how = np.mean

    if isinstance(df.index, pd.DatetimeIndex) and isinstance(rule, str):
        return df.resample(rule, how, **kwargs)
    else:
        idx, bins = pd.cut(df.index, range(df.index[0], df.index[-1]+2, rule), right=False, retbins=True)
        aux = df.groupby(idx).apply(how)
        aux = aux.set_index(bins[:-1])
        return aux
