How to Efficiently Add () and Insert into MySQL using Python

Are you new to Python and finding it challenging to format the results of file scanning for database insertion? You’re not alone! Many beginners face difficulties when trying to modify the output from Python scripts before inserting them into databases like MySQL. In this blog, we will break down the problem, provide a clear solution, and guide you through the implementation step by step.

The Problem

You have a Python script that scans a directory for .mp4 files and collects them in a list. Your aim is to take this list and format it suitably for insertion into a MySQL database. Specifically, each entry in the list needs to be wrapped in parentheses () along with a new variable (in this case, newip). Here's the initial scan result you’re dealing with:

The desired output for the SQL insertion should look like this:

The Solution

To achieve this, you can utilize list comprehension in Python, which is a concise way to create lists. Below are the detailed steps to modify your output effectively.

Step 1: Prepare Your Environment

Ensure you have all the necessary packages installed. You have already set up mysql.connector and imported os and uuid, as shown in your initial code.

Step 2: Modify Your Code

Instead of manually crafting the input list for insertion, follow these steps:

Scan the directory and store files – You already have this part set up.

Use List Comprehension – This is where the magic happens! Instead of hard-coding the insertion values, automatically append newip to each filename.

Here's how the modified code snippet looks:

Step 3: Run Your Script

Now that you have made these modifications, running your script should yield the following results:

It will scan the directory.

Properly format each file name with the newip.

Insert the values into your MySQL database.

Step 4: Verify the Results

You should see output similar to this:

Conclusion

With the above guide, you can efficiently add parentheses and associated variables to your Python script outputs before inserting them into a MySQL database. Utilizing list comprehension simplifies the process and ensures your code remains clean and readable. Happy coding!
