Python is a popular programming language in the field of data analysis due to its versatility, ease of use, and extensive libraries for data manipulation, visualization, and analysis. Here are some key Python skills that are important for data analysts:

1. Basic Python Programming: Understanding basic Python syntax, data types, control structures, functions, and object-oriented programming concepts is essential for data analysis in Python.

2. NumPy: NumPy is a fundamental package for scientific computing in Python. It provides support for large multidimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays.

3. Pandas: Pandas is a powerful library for data manipulation and analysis in Python. It provides data structures like DataFrames and Series that make it easy to work with structured data and perform tasks such as filtering, grouping, joining, and reshaping data.

4. Matplotlib and Seaborn: Matplotlib is a versatile library for creating static, interactive, and animated visualizations in Python. Seaborn is built on top of Matplotlib and provides a higher-level interface for creating attractive statistical graphics.

5. Scikit-learn: Scikit-learn is a popular machine learning library in Python that provides tools for building predictive models, performing clustering and classification tasks, and evaluating model performance.

6. Jupyter Notebooks: Jupyter Notebooks are an interactive computing environment that allows you to create and share documents containing live code, equations, visualizations, and narrative text. They are commonly used by data analysts for exploratory data analysis and sharing insights.

7. SQLAlchemy: SQLAlchemy is a Python SQL toolkit and Object-Relational Mapping (ORM) library that provides a high-level interface for interacting with relational databases using Python.

8. Regular Expressions: Regular expressions (regex) are powerful tools for pattern matching and text processing in Python. They are useful for extracting specific information from text data or performing data cleaning tasks.

9. Data Visualization Libraries: In addition to Matplotlib and Seaborn, data analysts may also use other visualization libraries like Plotly, Bokeh, or Altair to create interactive visualizations in Python.

10. Web Scraping: Knowledge of web scraping techniques using libraries like BeautifulSoup or Scrapy can be useful for collecting data from websites for analysis.

By mastering these Python skills and applying them to real-world data analysis projects, you can enhance your proficiency as a data analyst and unlock new opportunities in the field.

⦁ 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.
