Pandas to_csv in for loop AttributeError: 'tuple' object has no attribute 'to_csv'

[Yoriz]

This seems to work, not sure if it the best way though

import pandas as pd
  
data = pd.read_csv("some_data.csv")
data.Result_Notes = data.Result_Notes.astype(str)
data.Result_Header = data.Result_Header.astype(str)
  
for index, series in data.iterrows():
    desired_number = series['Number_Header']
    data.at[index, 'Result_Header'] = desired_number
    data.at[index, 'Result_Notes'] = 'This is your desired number'
  
print(data)  
data.to_csv("some_data_output.csv")

Output:
  Account_Number Invoice_Date Invoice_Number Payor  Ground_Tracking_ID_Prefix             ...               Status  Reason  Exception      Result_Header                 Result_Notes
