There are two ways to handle the situation where we do not want the index to be stored in csv file.
As others have stated you can use index=False while saving your
dataframe to csv file.df.to_csv('file_name.csv',index=False)- Or you can save your dataframe as it is with an index, and while reading you just drop the column unnamed 0 containing your previous index.Simple!
df.to_csv(' file_name.csv ')
df_new = pd.read_csv('file_name.csv').drop(['unnamed 0'],axis=1)
Can I append to an existing CSV file?
Yes, use `mode='a'` to append:\n\n```python\ndf.to_csv('data.csv', mode='a', header=False)\n```\n\nExclude the header to avoid repeating column names.
