You can specify the delimiter when creating a csv.writer or csv.DictWriter object. of 0, negative, or "" will only insert newlines. By default, this module accepts and outputs (when present in the original We use the writeheader method to write the fieldnames as the header of the CSV string: Finally, we loop through the list of dictionaries, writing each dictionary as a row in the CSV string using the writerow method: In the end, our code should look like this: When you run this script, you will see the following output: This shows that our list of dictionaries has been successfully converted to a CSV string. In other words, it can store different types of data (like integers, strings, and even other lists) in an ordered sequence. return value of object_pairs_hook will be used instead of the Introduction to Websockets library in python. However, you can use a different delimiter if needed. np.int32 or np.float32) to the "nearest compatible Python type" (in a list).
