Here is a Python function to create a mongodb index using the Python function

import pymongo

def create_mongodb_index(db_name, collection_name, index_name):
    """
    create mongodb index using
    """
    try:
        client = pymongo.MongoClient('mongodb://localhost:27017/')
        db = client[db_name]
        coll = db[collection_name]
        coll.create_index(index_name, {'_id': '$exists'})
    except Exception as e:
        print(e)

# Enter the string
db_name = "mydb"
collection_name = "mydb_collection"
index_name = "mydb_index"

# Calling the function
print((create_mongodb_index(db_name, collection_name, index_name)))

#Example Output
# 'dict' object has no attribute 'in_transaction'
# None

#Remember to inspect code for bugs.
