how to get list of all databases in a mongo instance using pymongo

Question

how to get the list of all the databases in a mongo instance to a variable using pymongo?

for example to send following command to mongo instance using pymongo,

db.adminCommand( { listDatabases: 1 } )

Answer 1

Use database_names

dbs = MongoClient().database_names()

As Andrew Allaire points out: Starting in pymongo 3.6 database_names() has been deprecated in favour of list_database_names.

dbs = MongoClient().list_database_names()
