Introduction to Python:
Matplotlib: A plotting library for Python that helps visualize data in various formats like line plots, histograms, scatter plots, etc.
Dictionaries: Data structures that store key-value pairs, allowing efficient data retrieval based on keys.
Pandas: A powerful library for data manipulation and analysis in Python, primarily used for handling structured data through its DataFrame objects.
Logic, Control Flow, and Filtering: Concepts involving conditional statements, loops, and filtering data based on certain conditions.
Loop Data Structures: Iterative structures in Python such as for and while loops.
Python Data Science Toolbox:
User-Defined Function: Functions created by users to perform specific tasks, enhancing code reusability and modularity.
Scope: The visibility of variables in different parts of the code.
Nested Function: A function defined inside another function.
Default and Flexible Arguments: Assigning default values to function parameters and handling variable numbers of arguments.
Lambda Function (Anonymous Function): Small, anonymous functions defined without a name using the lambda keyword.
Iterators: Objects that allow iterating through elements in a sequence.
List Comprehension: A concise way to create lists in Python based on existing lists or iterables.
Cleaning Data:
Diagnose Data for Cleaning: Identifying issues or inconsistencies in the dataset.
Exploratory Data Analysis (EDA): Analyzing data to summarize its main characteristics using various visualization and statistical methods.
Visual Exploratory Data Analysis: Using visual tools to understand the dataset's features and relationships.
Tidy Data: Structuring data in a standardized way for easier analysis.
Pivoting Data: Restructuring data to better analyze relationships between variables.
Concatenating Data: Combining datasets along axes.
Pandas Foundation:
Building Data Frames from Scratch: Creating Pandas DataFrame objects manually.
Statistical Exploratory Data Analysis: Analyzing data using statistical techniques.
Indexing Pandas Time Series: Working with time series data in Pandas.
Resampling Pandas Time Series: Changing the time frequency of the data.
Manipulating DataFrames with Pandas:
Indexing DataFrames: Accessing specific rows or columns in a DataFrame.
Slicing DataFrames: Extracting subsets of data from DataFrames.
Filtering DataFrames: Selecting rows or columns based on specific conditions.
Transforming DataFrames: Modifying DataFrame structures or values.
Index Objects and Labeled Data: Working with index labels in Pandas.
Hierarchical Indexing: Creating and working with multi-level index structures.
Stacking and Unstacking DataFrames: Changing the layout of DataFrames.
Melting DataFrames: Transforming wide-format data into long-format data.
Categoricals and Groupby: Working with categorical data and grouping data based on specific variables.
Each of these concepts is crucial in data manipulation, analysis, and visualization using Python.
