How to stop writing a blank line at the end of csv file - pandas

Question

When saving the data to csv, data.to_csv(\'csv_data\', sep=\',\', encoding=\'utf-8\', header= False, index = False), it creates a blank line at the end of csv f

Answer 1

A more efficient way is to open the file first, write to that stream, then remove the last newline:

import os
with open('csv_data', 'wb') as dst:
    data.to_csv(wb, sep=',', encoding='utf-8', header= False, index = False)
    dst.seek(-1, os.SEEK_END) # <---- 1 : len('\n')
    dst.truncate()
