rolling_window = 120
df = df.rolling(rolling_window, min_periods=1).agg(['mean','std'])
df.columns = df.columns.map('_'.join)
# df = df.reset_index()
df = df.iloc[(rolling_window-1):,]
df = df.rename_axis('timestamps').reset_index()
df = df.set_index('timestamps')

CodePudding user response：

df.reset_index(drop=True)

The drop attribute specifies whether the previously used index column should be removed.
