🚀 Turning Raw Text into Structured Data with Python Most people jump straight to libraries. I decided to master the logic first. Today, I built a Python function that extracts dates from unstructured text using regular expressions — the same kind of problem you face in bills, invoices, logs, and documents. 🔍 What it does: ✔ Detects multiple date formats ✔ Works on messy, real-world text ✔ Returns clean, usable data 📌 Formats handled: • DD/MM/YYYY • DD-MM-YYYY • Textual dates like 12 Apr'19 This is fundamentals done right — and that’s what scalable systems are built on. Next up: integrating this logic with OCR to extract dates directly from bill images. Learning by building. No shortcuts. 1️⃣ Input Text The program takes any raw text, such as invoices, bills, or documents. 2️⃣ Identify Date Patterns It knows multiple common date formats and looks for them inside the text. 3️⃣ Extract & Filter All matching dates are extracted while automatically removing duplicates. 4️⃣ Output Clean Data The final result is a list of all dates found in the text. #Python #Regex #TextProcessing #ProblemSolving #BackendDevelopment #AIMLJourney #BuildInPublic

XScraper - Easy to use Python based X Scraper tool ⛏️ Hi gng, I just fixed all the bugs I noticed in the algorithm and added a proper UI to make it much easier to use. More importantly, I improved the logic significantly. It is now able to continue scraping specific dates even after getting rate-limited, making it perfect for collecting data that appears often daily. See the attachment below for a demo searching for posts related to "fufufafa". New Features: - Performance: Can handle around 1,000 posts every 15 minutes. - Language Filter: Added ability to filter scraping by post language.

hi connections I'm nearing the finish line! Day 28 of #30DaysOfCode focused on Regular Expressions (RegEx) and data filtering. The Mission: Given a list of users, identify those with @gmail.com accounts and generate an alphabetically sorted list of their first names. Why RegEx? Without Regular Expressions, validating strings can involve messy, hard-to-read nested loops and string slicing. With RegEx, I can define a precise pattern (like r"@gmail\.com$") to filter data with surgical precision. Key Takeaways: Efficiency: RegEx makes pattern matching significantly faster than manual string checking. Data Integrity: Ensuring your data meets specific criteria is the first step to building reliable databases. Sorting: Using Python’s .sort() to present data in a user-friendly way. Only two days left in the challenge! The momentum is real. 🚀 #Python #Regex #DataValidation #CodingChallenge #HackerRank #SoftwareEngineering #ContinuousLearning #30DaysOfCode

Python provides a wide range of libraries and frameworks that enable the development of robust and efficient applications. In this project, I developed a simple yet visually engaging application using the Streamlit framework, combined with widely used data analysis libraries such as Pandas and Matplotlib. These tools facilitate data processing and visualization, and can also be integrated with artificial intelligence models to perform analytical consultations, generate insights, and provide recommendations aimed at improving the interpretation and quality of the results.

Big news from HumemAI: we just released ArcadeDB Embedded Python Bindings. 🚀 If you build in Python but want a serious database engine underneath, this is a new way to work: ArcadeDB runs embedded inside your Python process. 🐍⚡️ No driver hop. No separate DB service to manage. Much lower latency for local-first workloads. 🧠📍 You can simply install it with: `uv pip install arcadedb-embedded` 📦✅ Why we built it: A lot of “AI memory” isn’t just embeddings. You need structure, relationships, transactions, and fast retrieval. ArcadeDB gives tables + documents + graphs + vectors in one engine, and we wanted it to feel natural from Python. 🧩🔗🔎 What you get: - Python-first API for database + schema + transactions 🧱 - SQL and OpenCypher when you want them 🗣️ - HNSW vector search via JVector for nearest-neighbor retrieval 🧠➡️🧠 - A truly standalone wheel: lightweight JVM 25 (jlink) + required JARs + JPype bridge ☕️🔧 Repo: https://lnkd.in/eSNxpD6W Docs: https://lnkd.in/eTh6xdjs Video: https://lnkd.in/enSszpQy 🎥 If you’re building local-first AI apps, agent memory, or hybrid graph + vector retrieval, I’d love feedback and contributions. 🙌 #Python #ArcadeDB #OpenSource #Vectors #GraphDatabase #EmbeddedDatabase

🐍 90 Days of Python – Day 25 String Manipulation in Python | Working with Text Data Today, I focused on string manipulation in Python, a core skill for handling text data, user inputs, and preprocessing data for analytics and machine learning. 🔹 Concepts covered today: ✅ Creating and accessing strings ✅ String indexing and slicing ✅ Common string methods (lower, upper, strip, replace) ✅ Splitting and joining strings (split, join) ✅ String formatting using f-strings ✅ Understanding string immutability Strings are heavily used in: Data cleaning Feature engineering Handling CSV/JSON data NLP and predictive analytics workflows Learning how to manipulate strings efficiently helps write cleaner, more readable, and more Pythonic code. 📌 Day 25 completed — getting comfortable with text processing in Python. 👉 Which string method do you use the most in your projects? #90DaysOfPython #PythonStrings #LearningInPublic #PythonForData #DataAnalytics #PredictiveAnalyticsJourney

🚀 Day 3 of Python Learning – Operators & Expressions 🐍 Today, I explored one of the most important building blocks of Python: Operators and Expressions, with special focus on Relational and Bitwise operators. 🔹 Relational Operators Used to compare values and return boolean results (True or False): ==, != >, < >=, <= 👉 These are extremely useful for data filtering, comparisons, and decision-making in Data Analytics. 🔹 Bitwise Operators These operators work at the binary (bit) level: & (AND), | (OR), ^ (XOR) ~ (NOT) << (Left shift), >> (Right shift) 👉 Helpful in performance optimization, low-level computations, and certain IT applications. 🔹 Other Operators in Python include: Arithmetic operators (+, -, *, /, %) Logical operators (and, or, not) Assignment operators (=, +=, -=) Membership & Identity operators (in, is) 🔹 Expressions are combinations of variables, values, and operators that Python evaluates to produce a result. They play a major role in: Writing conditions Data filtering Calculations and analysis As someone interested in Data Analytics, understanding operators and expressions is essential for data manipulation, logical reasoning, and writing efficient Python code. This foundation is highly useful in real-world IT and analytics projects. 📌 One step closer to becoming confident with Python fundamentals! #Python #PythonLearning #Day3 #DataAnalyst #DataAnalytics #IT #Programming #CodingJourney #LearningInPublic #AnalyticsSkills
