How to list MongoDB collection names in Python using pymongo

This example will connect to the MongoDB running at localhost (on the default port 27017) without any username or password and open the database named mydb (also see Python MongoDB minimal connect example using pymongo) and list all the collection names in mydb:

from pymongo import MongoClient
client = MongoClient("mongodb://localhost")
db = client["mydb"]


This will print, for example,

['people', 'salaries']
