如何合併熊貓系列，並添加共同的價值觀

我有兩個熊貓系列（pandas.core.series.Series），我想合併成一個單一系列，增加對公共密鑰的值，例如：如何合併熊貓系列，並添加共同的價值觀

series1:

Act of Parliament of Ontario          1

讓我們嘗試用pd.concatsum：

series3 = pd.concat([series1,series2]).sum(level=0)

輸出：

0 
AAA Championship Car season        1 
ATP Buenos Aires           1 
ATP World Tour Finals         1 
Act of Parliament of British Columbia     1 
Act of Parliament of Ontario        1 
Act of Parliament of the United Kingdom     36 
Act of Parliament of the United Kingdom election law  2 
Name: 1, dtype: int64

您可以使用pandas.Series.sum()https://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.add.html 還提供了一種方法來填補缺失值。

例如，您的代碼可能是

series3 = series1.add(series2, fill_value=0)

full_df = (
    pd.concat([series1, series2], axis = 0) 
     .groupby(level=0) 
     .sum() 
)
