Section 1.1: The Map Function

The map() function in Python allows users to process elements within an iterable without writing explicit loops. By applying a given function to every item in the iterable, it produces what is known as a map object.

Section 1.2: Working with Numbers

In data science, numbers are fundamental. Python supports various numeric types that can be manipulated in code. Experts utilize this feature to construct the core components of computational and mathematical logic.

Section 1.3: Utilizing Itertools

The itertools library is a powerful part of Python's standard toolkit. It provides numerous methods that help write clean, efficient, and memory-conscious code, enabling lazy evaluations. This module contains various iterator building blocks, forming what is often referred to as "iterator algebra."

Section 1.4: Understanding Decorators

Decorators are a metaprogramming feature in Python that adds functionality to existing code without altering its original structure. They start with a function, enhance it with additional features, and return the original function.

Section 1.5: The Magic of Dunder Methods

Dunder methods, often called magic methods, are unique functions that begin and end with double underscores. They allow programmers to streamline their code and minimize the time spent on function calls.

Section 2.1: Mastering Strings

In Python, strings consist of alphanumeric values enclosed in either single or double quotes. The language offers numerous string manipulation capabilities, making it particularly useful for intermediate programmers involved in data science.

Section 2.2: Comparison Operators

Comparison operators enable coders to compare two operands, returning a boolean value—true or false—based on the comparison.

Section 2.3: Exploring Collections

Python collections utilize specialized containers like sets, tuples, dictionaries, and lists for data storage. The collections module provides various specific datatypes tailored for these containers.

Section 2.4: Exception Handling

For intermediate Python developers, mastering exception handling is crucial. Understanding how to identify and resolve errors that arise during program execution is essential for maintaining smooth program flow.

Section 2.5: The Power of Lambda Functions

Lambda functions in Python represent short, anonymous functions defined in a single line of code. While regular functions use the def keyword, lambda functions utilize the term lambda. These are particularly handy for tasks like updating content in DataFrames.
