Python MongoDB Create Collection

 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":

import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["mydatabase"]

mycol = mydb["customers"]

Important: In MongoDB, a collection is not created until it gets content!

Remember: 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:

collist = mydb.list_collection_names()
if "customers" in collist:
  print("The collection exists.")
