问题描述
我正在尝试使用常见的序列号合并两个Excel工作表,但是会引发一些错误.我的程序如下:
I'm trying to merge two excel sheets using the common filed Serial but throwing some errors. My program is as below :
(user1_env)root@ubuntu:~/user1/test/compare_files# cat compare.py
import pandas as pd
source1_df = pd.read_excel('a.xlsx', sheetname='source1')
source2_df = pd.read_excel('a.xlsx', sheetname='source2')
joined_df = source1_df.join(source2_df, on='Serial')
joined_df.to_excel('/root/user1/test/compare_files/result.xlsx')
出现如下错误:
(user1_env)root@ubuntu:~/user1/test/compare_files# python3.5 compare.py
Traceback (most recent call last):
File "compare.py", line 5, in <module>
joined_df = source1_df.join(source2_df, on='Serial')
File "/home/user1/miniconda3/envs/user1_env/lib/python3.5/site-packages/pandas/core/frame.py", line 4385, in join

File "/home/user1/miniconda3/envs/user1_env/lib/python3.5/site-packages/pandas/tools/merge.py", line 39, in merge
return op.get_result()

rdata.items, rsuf)

to_rename)
ValueError: columns overlap but no suffix specified: Index(['Serial'], dtype='object')

推荐答案
小的修改对我有用,
import pandas as pd
source1_df = pd.read_excel('a.xlsx', sheetname='source1')
source2_df = pd.read_excel('a.xlsx', sheetname='source2')
joined_df = pd.merge(source1_df,source2_df,on='Serial',how='outer')
joined_df.to_excel('/home/gk/test/result.xlsx')
