MongoDB waits until you have created a collection (table), with at least one document (record) before it actually creates the database (and collection).In [6]:

import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["valdb01"]

mycol = mydb["customers"] #create a collection

Inserting into collection

To insert a record, or document as it is called in MongoDB, into a collection, we use the insert_one() method.

The first parameter of the insert_one() method is a dictionary containing the name(s) and value(s) of each field in the document you want to insert.

In [9]:

#Insert a document (record) in the customers collection
import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")
mydb = myclient["valdb01"]
mycol = mydb["customers"]

mydict = { "name": "John", "address": "Highway 37" }

x = mycol.insert_one(mydict)
print(x)

<pymongo.results.InsertOneResult object at 0x0000011D7624EE00>

In [10]:

print(myclient.list_database_names())

['admin', 'config', 'local', 'valdb01']

In [11]:

dblist = myclient.list_database_names()
if "valdb01" in dblist:
  print("The database exists.")

The database exists.

mydict = { "name": "Peter", "address": "Lowstreet 27" }

x = mycol.insert_one(mydict)

print(x.inserted_id)
