Is it possible to use variable for collection name using PyMongo?

PyMongo is a Python distribution containing tools for working with MongoDB. Use the following syntax to use a variable for collection name −

var yourVariableName="yourCollectionName";

db[storeCollectionName].yourOperationName;

To understand the above syntax, let us create a collection with the document. The query to create a collection with a document is as follows. We have used variable for collection name −

> var storeCollectionName="new_Collection";

> db[storeCollectionName].insertOne({"UserName":"John","UserAge":21});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5c912aea4afe5c1d2279d6a0")
}
> db[storeCollectionName].insertOne({"UserName":"Carol","UserAge":24});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5c912af54afe5c1d2279d6a1")
}
> db[storeCollectionName].insertOne({"UserName":"Mike","UserAge":27});
{
   "acknowledged" : true,
   "insertedId" : ObjectId("5c912afe4afe5c1d2279d6a2")
}

Display all documents from a collection with the help of find() method. The query is as follows −

> db[storeCollectionName].find().pretty();

The following is the output −

{
   "_id" : ObjectId("5c912aea4afe5c1d2279d6a0"),
   "UserName" : "John",
   "UserAge" : 21
}
{
   "_id" : ObjectId("5c912af54afe5c1d2279d6a1"),
   "UserName" : "Carol",
   "UserAge" : 24
}
{
   "_id" : ObjectId("5c912afe4afe5c1d2279d6a2"),
   "UserName" : "Mike",
   "UserAge" : 27
}
