You are using Python 2 methodology instead of Python 3   Change   outfile open    immates csv   wb     To   outfile open    immates csv   w     and you will get a file with the following output   SNo States Dist Population 1 Andhra Pradesh 13 49378776 2 Arunachal Pradesh 16 1382611 3 Assam 27 31169272 4 Bihar 38 103804637 5 Chhattisgarh 19 25540196 6 Goa 2 1457723 7 Gujarat 26 60383628         In Python 3 csv takes the input in text mode  whereas in Python 2 it took it in binary mode   Edited to Add  Here is the code I ran   url  http   www mapsofindia com districts-india   html   urllib request urlopen url  read   soup   BeautifulSoup html  table soup find  table   attrs   class   tableizer-table    list of rows    for row in table findAll  tr   1        list of cells        for cell in row findAll  td            list of cells append cell text      list of rows append list of cells  outfile   open    immates csv   w   writer csv writer outfile  writer writerow   SNo    States    Dist    Population    writer writerows list of rows
