Excel vs Python Data Handling: Focus on Relevant Data

I thought Python was just doing calculations, until it gave me a “wrong” answer 😅 I was like: “How is this even possible??” Then I discovered something that changed everything Operators don’t just run, they follow rules. Let me explain this like I’m talking to a baby Imagine 3 kids solving math Kid 1: “Let’s go left to right” Kid 2: “No, start from the right” Kid 3: “Follow the rules first!” That’s exactly how Python behaves. What are Operators?Operators are just symbols like: ➕ ➖ ✖️ ➗ ** % They tell Python what to do with numbers. Python doesn’t just calculate randomly. It follows priority + binding rules. Two important rules I learned Modulo (%) → Left to Right For example: 20 % 6 % 4 = (20 % 6) % 4 = 2 % 4 = 2 Exponent (**) → Right to Left For Example: 2 ** 3 ** 2 = 2 ** (3 ** 2) = 2 ** 9 = 512 🤯 I used to think python is giving wrong answers Now I know that python is always correct, I just didn’t understand the rules. As I grow from excel to SQL and to Tableau and now python I’m learning that: Small mistakes = wrong insights Wrong insights = wrong decisions And in data, that’s dangerous Python is not confusing, it’s just very obedient to its rules. If you’re learning python, have you ever been surprised by a result like this? 😅 #Python #DataAnalytics #LearningInPublic #SQL #Excel #Tableau #Programming #TechJourney #BeginnerInTech #DataScience #CareerGrowth

📘 Today’s Learning: Clearing Null Values in Python Pandas using Imported Excel Data 🐼📊 Worked on handling missing/null values after importing Excel files into Python using Pandas. Data cleaning is one of the most important steps before analysis. 🔹 Key Steps Learned: ✅ Import Excel file using "pd.read_excel()" ✅ Check null values using "isnull()" / "isna()" ✅ Remove null rows using "dropna()" ✅ Fill missing values using "fillna()" ✅ Prepare clean data for analysis 💻 Example: import pandas as pd df = pd.read_excel("data.xlsx") # Check null values print(df.isnull().sum()) # Fill null values df.fillna(0, inplace=True) # Drop null rows df.dropna(inplace=True) Cleaning data improves accuracy and makes analysis more reliable.

I completed 10+ Python projects… but still got stuck at pd.read_csv() Sounds funny? But this is one of the most common real-world problems in Data Cleaning and Data Analysis projects. Many beginners think the problem is in Pandas. The truth? The real issue is usually the **file path**. Today I want to share the 5 easiest hacks I use as a Python Data Cleaning expert to read CSV files in one go. 1) Same folder hack Keep your CSV file in the same folder as your notebook/script. Then simply use: pd.read_csv("sales.csv") 2) Check the current working directory Before reading the file, always run: os.getcwd() This instantly tells you where Python is searching for the file. 3) Full path method Use the complete file path for 100% accuracy: pd.read_csv(r"C\Users\Monika\Desktop\sales.csv") 4) os.path.join() professional hack Perfect for GitHub and scalable projects: os.path.join(folder, file) 5) pathlib modern hack The cleanest and smartest way: Path("data") / "sales.csv" **Golden Rule:** Whenever a CSV file is not loading, first check: os.getcwd() This single line solves 80% of CSV path issues. Know any other simple tricks for working with CSV files in Python?

🚀 Today’s Learning in Python Pandas 🐍📊 Explored some powerful Pandas functions that help in data analysis and understanding datasets efficiently. These functions are widely used in real-world projects for summarizing, cleaning, and extracting insights from data. ✅ value_counts() – Counts the frequency of unique values in a column. Useful for checking repeated categories or values. Python df["City"].value_counts() ✅ unique() – Returns all unique values from a column. Helpful to know different categories available in the dataset. Python df["City"].unique() ✅ nunique() – Gives the total number of unique values in a column. Great for quick summary statistics. Python df["City"].nunique() ✅ groupby() – Groups rows based on a column and performs aggregate operations like sum, mean, count, max, min, etc. Very useful for business insights and reporting. Python df.groupby("Department")["Salary"].mean() 📌 Learning these functions makes data exploration faster and easier. They are essential for every Data Analyst and Data Science beginner. #Python #Pandas #DataAnalytics #DataScience #LearningJourney #LinkedInPost #CodingJourney #DataCleaning #MachineLearning

Introduction to Python Python is one of those tools I almost talked myself out of learning… before even starting. Fear can be funny like that. (Same thing happened with Tableau… now look who uses Tableau ....Meeee) I’ve just started my journey into Python for data analysis, and here’s what I’ve learned so far: Python is a general-purpose programming language widely used in data analysis, automation, and machine learning. It was created by Guido van Rossum and released in 1991. Right now, I’m learning with Jupyter Notebook and starting with the basics: VARIABLES Variables are simply containers for storing data. Think of them like labeled boxes: Label = variable name Content = value Example: x = 22 name = 'Sero' price = 9.99 Python automatically understands the data type: 22 → integer 'Sero' → string 9.99 → float You can also check using: print(type(x)) A few things I found interesting: 1. Variables are case-sensitive (x ≠ X) 2. You can assign multiple variables at once 3. You can assign one value to multiple variables Still early days… but consistency over perfection.What was your first experience learning Python like?

Most Data Analysts are using tools wrong… They spend months learning Excel. SQL. Python. But still struggle to create real impact. Here’s the truth 👇 👉 Excel is for speed 👉 SQL is for data access 👉 Python is for depth Individually, they’re useful. Together, they’re powerful. The real skill is not in tools — it’s in asking the right questions and solving the right problems. In my workflow: ✔ SQL → extract data ✔ Python → clean & analyze ✔ Excel → present insights That’s where real value is created. Tools don’t make you a Data Analyst. How you THINK does.

From Confused Terms to Clear Concepts My Python Journey Today I realized something powerful… Learning Python isn’t about memorizing 100+ terms. It’s about connecting them into a story. At first, words like DataFrame, Boolean masking, groupby(), ndarray, merge() felt overwhelming. But when I slowed down, everything started to click A DataFrame became more than rows & columns it became a way to tell stories with data. Boolean masking turned into a smart filter like asking data, “Show me only what matters.” groupby() + agg() felt like zooming out turning raw numbers into meaningful insights. Even simple things like lists, dictionaries, and sets became building blocks of logic. And then it hit me: 1️⃣ Data analysis is not about tools. 2️⃣ It’s about thinking clearly. From CSV files → DataFrames → Insights From raw data → decisions → impact That’s the real journey. I’m still learning, still improving but now I see the bigger picture. And honestly, that changes everything. 💡 If you're starting Python or Data Analytics: Don’t rush. Don’t memorize. Understand → Apply → Repeat. Because once concepts connect… You stop learning syntax and start solving problems. #Python #DataAnalytics #Pandas #NumPy #LearningJourney #DataScience #TechSkills #GrowthMindset #GrowWithGoogle
