Answer 1

DeprecationWarning: collection_names is deprecated. Use list_collection_names instead.

Changed in version 3.7: Deprecated. Use list_collection_names() instead.

An example to read the database name from user input and then finding the list collection names would be:

import pymongo

myclient = pymongo.MongoClient("mongodb://localhost:27017/")

dbname = input("Enter database name: ")
mydb = myclient[dbname]

#list the collections
for coll in mydb.list_collection_names():
    print(coll)
