[Python] Python Data Scraping

Data Scraping in Pyhton. Code is working fine but it is showing the error which I mentioned below. What could be the reason?

import urllib2
from bs4 import BeautifulSoup
from xlwt import workbook

wb = Workbook()
sheet1 = wb.add_sheet('Sheet1')

soup = BeautifulSoup(urllib2.urlopen("http://en.wikipedia.org/wiki/List_of_Indian_satellites").read())

for row in soup('table', {'class': 'wikitable sortable jquery-tablesorter’})[0].tbody('tr'):
tds = row('td')
sheet1.write(row, 0, tds[0].string)
sheet2.write(row, 1, tds[1].string)

wb.save('Performance Project.xls')

Error: File "ProcessingProject.py", line 12 SyntaxError: Non-ASCII character '\xe2' in file ProcessingProject.py on line 12
