Resample Weekly into Daily CSV DataFrame

I have a database that releases weekly data on Friday afternoons, for data ending on the previous Tuesday. I am trying to re-sample that data into daily up to yesterdays date.



I keep running the code below, but it is not resampling into daily business days:



df=pd.concat([specl,specs,comml,comms,smalll,smalls], join='inner', axis=1)

df.resample('B').ffill()





python pandas

Maybe you forget the sum() method with resample?



df=pd.concat([specl,specs,comml,comms,smalll,smalls], join='inner', axis=1)

df = df.resample('B').sum().ffill()

  • Did you try df = df.resample('B').sum().ffill()
