Simple pandas question

[mcva]

This is a good solution...

import pandas as pd
import numpy as np

# Import data
data = pd.read_excel('moving_average.xlsx', index_col=0, header=0)

results = []
for i in range(100):
    tmp = data.rolling(i+1, center=False, axis=0).mean()
    results.append(tmp)

df=pd.concat(results, axis=1)

df.to_excel("output.xlsx")
