    The tell() method of the file object returns the current cursor position. Therefore, if the file is empty or doesn't exist, banbangcap.online==0 is True.Stack Overflow works best with JavaScript enabled.

    Use 'a' to append data into the file. index: False means do not include an index column when appending the new data. True means include an index.It is easier to read.

    [source]¶. Write DataFrame to a comma-separated values (csv) file File path or object, if None is provided the result is returned as a string.Alternatively, you can also read the original CSV as a dataframe, append additional data to it and then write the combined dataframe as a CSV file.
