Python Pandas 将 Excel 表单元格导入为 object 最后没有引号

Question

My example excel sheet looks like this:

Excel sheet data:

customer1_data.xlsx =

parameter                                       customer1                   
analysis                                                1
analysis_name                             1month_services
analysis_duration                [2022-08-23, 2022-11-02]
analysis_numcheck                                      1
analysis_dupcolumns                                    1

Import excel sheet data as dataframe It looks normal but when I query individual rows or cells, some cell values have quotes at the end. I don't want any quotes in the end.

c1df = pd.read_excel('customer1_data.xlsx')
c1df.set_index('parameter',inplace=True)
print(c1df)

parameter                                       customer1                   
analysis                                                1
analysis_name                             1month_services
analysis_duration                [2022-08-23, 2022-11-02]
analysis_numcheck                                      1
analysis_dupcolumns                                    1

Present output When I print individual cell values

print(c1df.loc['analysis'])
1

print(c1df.loc['analysis_duration'])
'[2022-08-23, 2022-11-02]'

print(c1df.loc['analysis_name'])
'1month_services'

Expected output:

print(c1df.loc['analysis'])
1

print(c1df.loc['analysis_duration'])
# I don't want any quotes at the end for the list here
[2022-08-23, 2022-11-02]

print(c1df.loc['analysis_name'])
# ' ' quote is expected for the string, no issues here

'1month_services'

You can use pandas.Series.split to convert string delimited to lists:

c1df["customer1"]= (
                    c1df["customer1"].str.strip("[]")
                                     .str.split(",")
                        .where(c1df["customer1"].str.contains("[\[\]]", regex=True, na=False))
                        .fillna(c1df["customer1"])
                    )
​

# Output:

print(c1df)

             parameter                  customer1
0             analysis                          1
1        analysis_name            1month_services
2    analysis_duration  [2022-08-23,  2022-11-02]
3    analysis_numcheck                          1
4  analysis_dupcolumns                          1


print(c1df.iloc[2,1])
['2022-08-23', ' 2022-11-02']
