Tip 1: Easily Convert an Image to LaTeX Code

Did you know there's this Python library called Pix2TeX that can magically transform images with equations into LaTeX code? Imagine how effortlessly you could integrate an equation from one document to another, without even needing to recreate it from scratch!

You can install the library using pip: pip install pix2tex[gui]

Let's look at an example.

Wow, that's fascinating! Or what do you think? This package simplifies the writing of theses or scientific papers massively. And best of all, it's completely free.

Tip 2: Automatically remove unused Python code

This tip can make your source code more clean. As you know, there is a lot of unused code in large software projects. Unused Python code can cause several problems, such as:

• Wasting memory and resources

• Making it harder to understand the code

• Challenges in testing and debugging of code

Curiously, there's a tool called vulture that can help you automatically remove unused Python code!

You can install the library using pip: pip install vulture

In the following, you can see an example:

The code represents a bank customer. First, we import pandas and then we define the customer class. In the main, we create a customer object. Then, we output the customer's account balance.

After that, we ran our script with the package vulture. The tool returns all code sections that are not currently in use (marked in red). With this tool, you can clean up your code very easily.

Tip 3: Best Practices to Protect Sensitive Information

Another quick tip for you - it's always a smart idea to keep sensitive info in a .env file and then load it into your Python script with the help of the Python package python-dotenv.

This way, you can keep your important data safe from accidentally showing up in your codebase or version control systems.

You can install the library using pip: pip install python-dotenv

In the following, you can see how you can use the package.

The code loads the OpenAI API key from a local .env file.

This procedure should be followed by all developers to avoid unnecessary costs caused by leaked information. Stay secure!

Tip 4: Schedule Python Functions with Rocketry

To schedule Python functions with easy-to-understand and customizable scheduling statements, use Rocketry. Unlike other tools, Rocketry makes no assumptions about the project structure. It is excellent for fast and efficient automation projects.

You can install the library using pip: pip install rocketry

The following code shows how you can use the library.

First, we import the package rocketry. Then, you can define tasks with the decorator @app.task(...) . Very easy or?

Tip 5: Generate Realistic Fake Data with Faker

Faker is a Python package that makes it easy to create fake but realistic data for testing. It can make names, addresses, zip codes, and more. Say goodbye to making test data by hand and improve your testing with Faker.

You can install the library using pip: pip install Faker

In the following, you can see some examples.

First, we import the package Faker and create an object. Then, you can use this object to generate realistic fake data (names, addresses, zipcodes and many more). Generating fake data is easier than ever before.

Tip 6: Tracking Your ML Experiments in an Easy Way

Tracking ML experiments is essential! But, you know that writing multiple log statements can be a bit of a hassle. To make things easier, you can add mlflow.autolog() before your training code for automatic logging.

And the best! We provide an open-source and docker-based MLflow Workspace to help you get started right away with tracking. You can download our MLflow Workspace from GitHub (Python examples included).

In the following, you can see a short demo video of how you can use our MLflow Workspace for automatic logging. You can find more information in the GitHub repo.

Have fun with the MLflow Workspace. Happy tracking!

Tip 7: Speed up Your Code with a Single Parameter

Large pandas dataframes can consume a large amount of memory. It's fascinating how processing data in smaller chunks can help prevent running out of memory and access data faster!

You can see an example in the figure.

Wow, it's approximately 7000 times faster! The next time you want to read large dataframes, you should remember this parameter.

Conclusion

In conclusion, these seven tips are designed to elevate your Python skills, boost productivity, and simplify your life as a Data Scientist or Data Engineer.

From effortlessly converting images to LaTeX code with Pix2TeX, to cleaning up your code with vulture, protecting sensitive data with python-dotenv, scheduling functions with Rocketry, generating fake data with Faker, tracking ML experiments with mlflow, and speeding up your code while dealing with large pandas dataframes, each tip adds a unique value.
