invalid syntax on line 110 in crawl.py

[rslu2000]

I run the program crawl.py in Mac OS using Python3. Then I got the invalid syntax message as the followings:
$ python3 crawl.py
" File "crawl.py", line 110
print 'Crawling {}'.format(date_str)
^
SyntaxError: invalid syntax"

Also the same results on using python2
