Remove document from mongodb using python

Question

Here Is my try to remove document with article_link:x

>>> db = client.article_db
>>> collection1 = db.article0510
>>> collection1.remove('article_link': 'http://www.moneycontrol.com/news/stocks-views/bet-for-long-termbharat-forge-hemant-thukral_3414941.html')
  File "<stdin>", line 1
    collection1.remove('article_link': 'http://www.moneycontrol.com/news/stocks-views/bet-for-long-termbharat-forge-hemant-thukral_3414941.html')
                                     ^
SyntaxError: invalid syntax

Here is my python script:

bse_tagged_link = ['http://www.business-standard.com/article/finance/sfio-probes-10-firms-in-bob-case-115102900994_1.html']
for link in bse_tagged_link:
    lookup_result = self.collection1.find({'article_link': link})
    print lookup_result
    for val in lookup_result:
        if val and val != 'None':
            print val
            self.collection1.remove({'article_link': var['article_link']})

What I want to do is:

Get set of links from table1
lookup links from point 1 into table 2
If link present in table2, remove those record

Your syntax to remove is incorrect, as evident by the error you got. You should use this syntax:

collection1.remove({"article_link" : "http://www.moneycontrol.com/news/stocks-views/bet-for-long-termbharat-forge-hemant-thukral_3414941.html"})
