尝试将数据框写入 .CSV - 权限被拒绝

Question

I am trying to write a datafame to a csv file using the following:

fxRollPath = 'C:\Users\stacey\Documents\scripts\FXFiles'
fxData.to_csv(fxRollPath,fxRoll'+ str(index)+'.csv')

Where fxRoll is a dataframe

But I get the error:

PermissionError: [Errno 13] Permission denied: 'C:\Users\stacey\Documents\scripts\FXFiles'

What have I done wrong?

Answer 1

Just realized, you are actually trying to save to a target directory path instead of file path.

Docs of path_or_buf for DataFrame.to_csv : "string or file handle, default None. File path or object, if None is provided the result is returned as a string."

So change your code to:

fxData.to_csv('{0}\{1}{2}{3}'.format(fxRollPath, fxRoll, str(index), '.csv'))

也许您需要关闭现在打开的 csv 的第一个版本

Answer 3

I got this problem too. Not sure if you have the same situation as me.

I had the same filename in the same directory and I wanted to override the old csv file. Instead of overriding the old file, I deleted it and then save it to solve this problem.

        os.remove('filename') 
        df.to_csv('filename.csv')
