What Triggered This Error?

The Solution: Correct Your Imports

The error surfaced because there was a conflict between two separate Font classes that you have imported simultaneously:

When both Font classes are imported, Python can't distinguish between them, which leads to confusion over the parameters accepted by each class, resulting in the TypeError. Here's how to resolve it:

Step-by-Step Fix

Identify Your Imports: Locate both import statements in your code.

Why This Works

Aliasing your imports makes it explicitly clear which Font class you are referring to in your code. This eliminates ambiguity, allowing your program to recognize the correct Font class with its associated parameters, thus resolving the TypeError error once and for all.

Conclusion

In conclusion, while encountering errors in programming can be disheartening, they often provide an opportunity to learn and improve your skills. By carefully checking your imports and correctly aliasing the Font class from openpyxl, you'll be able to set your cell formatting without any hassle. So next time you face a similar problem, remember the import conflict and use aliases for clarity.

Keep coding, and don't let errors stand in your way! If you have any more questions or would like to share your experiences, feel free to leave a comment below.
