How to dynamically code collection name inside a function?

I am trying to code a Python function to insert my CSV file to MongoDB database using MongoClient() but I don’t know how to dynamically code the collection name. Here is my code:

def write_toDB(file_name, my_key):
    ...
    db.file_name.insert_one(data)

If I write my code like above, the collection name will be “file_name” instead of the parameter file_name. Anyone knows how to fix this? Thank you!

Answer

You can reference the collection using this format:

def write_toDB(file_name, my_key):
    ...
    db[file_name].insert_one(data)
