pandas.DataFrame.to_csv问题（“ tuple”对象没有属性“ to_csv”）

Question

I have imported a csv file and manipulated the data with pandas. I would now like to write out the df to a csv, but am receiving error: 'tuple' object has no attribute 'to_csv'

I have tried the following:

   df = pd.read_csv(destintation_path + '/' + filename),
   index_col=False,
   usecols=[1,2,3], 
   parse_dates=[0],
   header=0,
   names=["lineItem_referenceNo", "lineItem_tenantId", "lineItem_intervalUsageStart"]
   logging.info(df)

   export_csv = df.to_csv(destintation_path + '/' + filename, header=True)

The returned message is:

'tuple' object has no attribute 'to_csv'

Any guidance appreciated.

Answer 1

Seems like you are closing you parenthesis too early. Try this corrected line:

df = pd.read_csv(destintation_path + '/' + filename,
   index_col=False,
   usecols=[1,2,3], 
   parse_dates=[0],
   header=0,
   names=["lineItem_referenceNo", "lineItem_tenantId", "lineItem_intervalUsageStart"])
logging.info(df)

Answer 2

I always use

df.to_csv("filename.csv" )

and this works fine for me. It outputs the csv to the same directory of my notebook.
