how to translate each and every row of csv file

Question

some words of the row are getting translated, sometimes and sometimes not.

from googletrans import Translator
myfile=open("ElectricCarData_Norm.csv")
f=myfile.readlines()

translator=Translator()  
with open("Electric.csv", 'w',encoding="utf-8") as op:      
  for line in f:
    #print(line)
    translation = translator.translate(line, src='en',dest='hi').text
    
  #print(line," ",translation)
    op.write(translation)
    op.write('\n')
