how to parameterize a mongodb query in python

I have a list with some mongodb queries in python, but I can't get data from some complicated queries that works in mongodb.

    sql = [        
        [
          {"$match": {
              "status": {"$in" : ["BUILDING"]}
              }
          }
          ,{"$group": {
              "_id": '$status', "count": {"$count": {}}
               }
            }
         ],        
     ]

     collection = client["send"]["sendEntity"]
     mydoc = list(collection.find(myquery))

The error is as follows:

<class 'TypeError'>
