✅ How Much Python is Enough to Crack a Data Analyst Interview? 🐍📊

Python is a must-have for data analyst roles in 2025—interviewers expect you to handle data cleaning, analysis, and basic viz with it. You don't need to be an expert in ML or advanced scripting; focus on practical skills to process and interpret data efficiently. Based on current trends, here's what gets you interview-ready:

📌 Basic Syntax & Data Types
⦁ Variables, strings, integers, floats
⦁ Lists, tuples, dictionaries, sets

🔁 Conditions & Loops
⦁ if, elif, else
⦁ for and while loops

🧰 Functions & Scope
⦁ def, parameters, return values
⦁ Lambda functions, *args, **kwargs

📦 Pandas Foundation
⦁ DataFrame, Series
⦁ read_csv(), head(), info(), describe()
⦁ Filtering, sorting, indexing

🧮 Data Analysis
⦁ groupby(), agg(), pivot_table()
⦁ Handling missing values: isnull(), fillna()
⦁ Duplicates & outliers

📊 Visualization
⦁ matplotlib.pyplot & seaborn
⦁ Line, bar, scatter, histogram
⦁ Styling and labeling charts

🗃️ Working with Files
⦁ Reading/writing CSV, Excel
⦁ JSON basics
⦁ Using with open() for text files

📅 Date & Time
⦁ datetime, pd.to_datetime()
⦁ Extracting day, month, year
⦁ Time-based filtering

✅ Must-Have Strengths:
⦁ Writing clean, readable Python code
⦁ Analyzing DataFrames confidently
⦁ Explaining logic behind analysis
⦁ Connecting analysis to business goals

Aim for 2-3 months of consistent practice (20-30 hours/week) on platforms like DataCamp or LeetCode. Pair it with SQL and Excel for a strong edge—many jobs test Python via coding challenges on datasets.
