Look at the lines preceding the one triggering the SyntaxError. Usually 
there is an opening (, [ or { which doesn't have a matching closing 
counterpart. 

In your case count the parens in the line

> DomainList = (str(DomainList).rstrip('/')

By the way, even without error this line will not have the desired effect.
Given 

>>> DomainList = ["facebook.com/", "twitter.com/"]

converting to string gives

>>> str(DomainList)
"['facebook.com/', 'twitter.com/']"

and as that doesn't end with a "/" applying the rstrip() method has no 
effect. Instead you can modify the line

> DomainList = [column[1] for column in DomainList]

where you can invoke the rstrip() method on every string in the list.
