I’ve been growing my Python skills recently, focusing on learning through practical work instead of just tutorials. This week, I built a small workflow using three core libraries: • requests to pull data from the web • pandas to organize and explore it • numpy to analyze it efficiently Even as someone who hasn’t traditionally identified as a “developer,” this helped connect the dots between data retrieval, structure, and insight. It made Python feel less theoretical and more useful in everyday work like automation, troubleshooting, and performance checks. I also wrote a blog post walking through these libraries and how they fit together. If you'd like to read it, here’s the link: 🔗 Blog Post: https://lnkd.in/gs3BXfzZ Small steps. Real learning. Progress that compounds. If you have recommendations on what I should explore next, I’m always open to learning from others.

I learned from the course on using Python with Excel. I'm grateful to Dr. Antoinette Smith, PhD, CPA, for introducing me to the foundation of automating in Excel. It was very useful to me, knowing I had a base knowledge of concepts such as ranges, indexes, for loops, and if-else statements. This was definitely helpful as an experience, with how Python can intersect with Excel worksheets. 1.) One takeaway from this section of the course was how naming and structuring data in Excel, just like in Python, can make our workflow cleaner, more readable, and far easier to automate. In the lesson, the instructor demonstrates how to use Openpyxl, which is used to define named ranges and tables directly within Excel workbooks. This is very useful when moving data between Python and Excel, maybe it can be used when working with pandas dataframes. The process begins with extracting unique values from a dataset. After, openpyxl allows you to create a named range, assigning a descriptive name to a specific group of cells. I used table functions to define a range. Once it is saved, the result is an Excel file where both ranges and formatted tables are accessible. 2.)I explored how to create Excel plots in Python. In the lesson, I worked with population data. Sort it by size from high to low first. After, you would send the pandas data to Excel. using a specific dataframe function. Then, using the Barchart function to make a bar chart. Once this is done, I used the reference function to add data and categories together. This reference function is what brings out the column values. Essentially, now the Workbook is done, and these is Excel bar chart created. The Excel chart looks exactly as one one would make it manually instead of utilizing python. 3. Conditional formatting is a powerful tool; it turns numbers into insights you can see. I learned how to create color-coded excel reports directly from Python using pandas and Openpyxl, meaning no manual clicking through Excel menus. I created a custom Python function to highlight cells, and expanded the idea to highlight entire rows based on value ranges. Comparing Excel’s manual formatting, these rules are somewhat more reproducible. If your data changes, you rerun the script, and the updated, colored report is ready efficiently. This approach used design, making reports faster to build and easier to read. Overall, I think utilizing Python and other software languages should be essential for anyone who wants to take Excel automation to the next level. https://lnkd.in/eVEPvJBk Just finished the course “Using Python with Excel! hashtag #python #c #excel

How to Build Your Own MCP Server with Python Artificial intelligence is evolving at a remarkable pace. Models today can reason, write, code, and analyze information in ways that once seemed impossible. But there’s one major limitation that still holds them back: context. Most AI models don’t have access to your system, files, APIs, or live data. They only know what you tell them in a prompt. The Model Context Protocol, also known as MCP, was created to address this problem. It enables AI models to securely connect to your own tools, APIs, and systems via small, structured servers known as MCP servers. In this guide, you’ll learn how to build your own MCP server using Python. We’ll walk through each part of the code and I’ll explain how it works... https://lnkd.in/d53J4jPk

Learning Python: Working with JSON Data After exploring file handling, I started learning how Python deals with structured data; especially JSON, which is everywhere in modern systems. APIs return it, tools log in it, and configurations often depend on it. In Python, working with JSON feels effortless. Example: import json with open("config.json", "r") as file: data = json.load(file) print(data["server"]["ip"]) Here, json.load() reads the JSON file and converts it into a Python dictionary, so you can access values directly using keys. To write data back into a JSON file: with open("output.json", "w") as file: json.dump(data, file, indent=4) What I like most is that Python handles JSON just like native data — lists, dictionaries, strings — no extra parsing complexity. For automation, it’s perfect for reading system configurations, API responses, or storing structured output.
