借助python或tableau合并数据

Question

我有2个Excel工作表，一个有63000行，另一个有67000行，其中包含职业，并且他们的可省略性都具有相同的标题，因此我根据标题进行了合并，但是输出显示了44,00,000行，为什么这样，请帮助我在这个问题上谢谢你，

Import pandas as pd
Df = pd.read_excel('c/downloads/knowledge.xlsx')
Df1 = pd.read_excel('c/downloads/Abilities.xlsx')
Df2 = pd .merge(df,df1,on = 'Title')

Answer 1

# Create a list of the files in the order you want to merge
all_df_list = [df, df1]

# Merge all the dataframes in all_df_list. Pandas will automatically append based on similar column names if that is what you meant by "same title".
appended_df = pd.concat(all_df_list)

# export as an excel file
appended_df.to_excel("data.xlsx", index=False)

让我知道是否有帮助。仅当两个文件中的标签相同时，该标签才有效。
