- Basic operations:
head()
,tail()
,info()
,describe()
.
Practice:
- Create your first Series and DataFrame.

Day 2: Data Input and Output
- Learn how to read and write data (CSV, JSON, Excel).
- Explore
pd.read_csv()
,pd.read_json()
, anddf.to_csv()
.
Practice:
- Load a dataset into a DataFrame and save it in a different format.
Day 3: Selecting and Filtering Data
- Indexing and slicing with
.loc[]
and.iloc[]
. - Filtering rows and selecting columns.
Practice:
- Filter rows based on conditions (e.g.,
Age > 30
). - Select specific columns and reorder them.
Day 4: Modifying DataFrames
- Add, rename, and delete columns.
- Sorting rows with
sort_values()
.
Practice:
- Add a new column to a DataFrame.
- Sort rows by multiple columns.
Day 5: Review and Mini-Project
- Review the topics covered so far.
- Work on a mini-project: Import a dataset, clean it, and explore basic statistics.
Week 2: Data Cleaning and Manipulation
Day 6: Handling Missing Data
- Identify missing data with
isnull()
. - Handle missing data with
dropna()
andfillna()
.
Practice:
- Clean a dataset with missing values.
Day 7: Cleaning Wrong and Duplicate Data
- Fix wrong formats and replace values.
- Remove duplicate rows with
drop_duplicates()
.
Practice:
- Standardize a messy dataset with formatting issues.
Day 8: Data Transformations
- Apply functions to DataFrames with
apply()
andmap()
. - Replace values with
replace()
.
Practice:
- Transform a column (e.g., convert prices to numeric values).
Day 9: Grouping and Aggregating Data
- Group data with
groupby()
and calculate aggregates. - Use pivot tables and crosstabs.
Practice:
- Group a dataset and calculate statistics for each group.
Day 10: Review and Mini-Project
- Review Week 2 topics.
- Mini-project: Clean and transform a real-world dataset (e.g., sales data).
Week 3: Advanced Techniques and Visualization
Day 11: Advanced DataFrame Operations
- Merge, join, and concatenate DataFrames.
- Reshape DataFrames with melting and stacking.
Practice:
- Merge two datasets and reshape a DataFrame.
Day 12: Working with Dates and Times
- Convert strings to datetime objects.
- Extract date and time components.
- Perform date arithmetic.
Practice:
- Analyze a time series dataset (e.g., sales over time).
Day 13: Analyzing DataFrames
- Calculate correlations with
corr()
. - Use rolling and expanding functions for advanced analysis.
Practice:
- Analyze trends in a dataset using rolling averages.
Day 14: Data Visualization
- Plot data directly with Pandas (
plot()
). - Customize plots with labels, legends, and colors.
Practice:
- Visualize trends and distributions in a dataset.
Day 15: Review and Mini-Project
- Review Week 3 topics.
- Mini-project: Analyze and visualize a dataset using advanced techniques.
Week 4: Real-World Applications and Practice
Day 16: Optimizing Pandas for Large Data
- Reduce memory usage by optimizing data types.
- Process large files in chunks.
Practice:
- Load and process a large dataset efficiently.
Day 17: Time Series Analysis
- Perform advanced time series analysis.
- Create time-indexed DataFrames.
Practice:
- Forecast trends using a time series dataset.
Day 18: Real-World Use Cases
- Work on domain-specific datasets (e.g., finance, healthcare).
- Integrate Pandas with other libraries like Matplotlib and Scikit-learn.
Practice:
- Apply Pandas to a dataset related to your field of interest.
Day 19: Final Project
- Use all the skills learned to clean, analyze, and visualize a complex dataset.
Example Project:
Analyze sales data to find trends, correlations, and actionable insights.
Day 20: Review and Next Steps
- Summarize your learnings.
- Explore advanced Pandas topics (e.g., Dask, Vaex).
- Set goals for the next phase of your learning journey.
