A collection in MongoDB is the same as a table in SQL databases.
To create a collection in MongoDB, use database object and specify the name of the collection you want to create. MongoDB will create the collection if it does not exist.
Create a collection called "customers":
Formula
import pymongo myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]
mycol = mydb["customers"]In MongoDB, a collection is not created until it gets content! MongoDB waits until you have inserted a document before it actually creates the collection.
In MongoDB, a collection is not created until it gets content, so if this is your first time creating a collection, you should complete the next chapter (create document) before you check if the collection exists! You can check if a collection exist in a database by listing all collections:
Return a list of all collections in your database:
print(mydb.list_collection_names())Or you can check a specific collection by name:
Check if the "customers" collection exists:
Formula
collist = mydb.list_collection_names()
if "customers" in collist:print("The collection exists.")
