如何从数据框中设置熊猫系列索引并用其他数据填充系列？

Question

I have a pandas dataframe myDataFrame with many columns and a multiple index(es) (two) I want to create a series that has the same indexing as my dataframe myDataFrame but at each row I set a value.

I was thinking of something along the lines of:

mySeries.set_index(myDataFrame.index)

for i in mySeries.index()
   mySeries.loc[i] = someValue
  

Thank you very much!

你可以做

 pd.Series(somevalue, index = df.index)
