问题

I get this error while i want to keep my dataframe in excel file which name pandas_simple.xlsx

Below is my error:

This is my code:

import pandas as pd
df = pd.DataFrame({'Car': [101, 20, 350, 20, 15, 320, 454]})
writer = pd.ExcelWriter('pandas_simple.xlsx')
df.to_excel(writer, sheet_name='Sheet1')
writer.save()
writer.close()

Anyone can share some idea to me here?

回答1:

You try to write to a folder where you need administration rights. Change:

writer = pd.ExcelWriter("pandas_simple.xlsx")

to:

writer = pd.ExcelWriter("C:\\...\\pandas_simple.xlsx")

with the full path and you will not have a problem.

回答2:

This error could also occur if you have a version of the same file (pandas_simple.xlsx in this case) already open in your desktop. In that case, python will not have permission to close and overwrite the same file. Closing the excel file and re-running the script should resolve the issue.

回答3:

The documentation of pandas.DataFrame.to_excel says that the first argument can be a string that represents the file path. In your case i would drop all lines with writer and just try

df.to_excel('pandas_simple.xlsx')

That should write pandas_simple.xlsx to your current working directory. If that does not work try to provide the full path name (e.g. C:\\Users\\John\\pandas_simple.xlsx). Also make sure that you don't try to write to a directory which needs adminstration rights.

What if the path is correct?!!!

Try closing the xlsx file opened in Excel application and run the code again, it worked for me and same should happen with you.

I am attaching my code snippet for your reference


    import pandas as pd

    file='C:/Users/Aladahalli/Desktop/Book1.xlsx'
    xls = pd.ExcelFile(file)

    df = pd.read_excel(xls, sheet_name='Sheet1')

    #create a column by name Final and store concatinated columns
    df["Final"] = df["Name"] + "    " + df["Rank/Designation"] + "    " + df["PS"]
    print(df.head())

    # Create a Pandas Excel writer using XlsxWriter as the engine.
    writer = pd.ExcelWriter('C:/Users/Aladahalli/Desktop/Final.xlsx', engine='xlsxwriter')

    # Convert the dataframe to an XlsxWriter Excel object.
    df.to_excel(writer, sheet_name='Sheet1')

    # Close the Pandas Excel writer and output the Excel file.
    writer.save()
    writer.close()
