• Explore Python's impressive range of features and discover why it's one of the most popular programming languages in the world

Book Description

Python Essentials provides a vital tour of the most critical features of Python. Starting with setup and installation, you will soon dive into exploring built-in-library types, Python's rich collection of operators and built-in functions, variables, assignment and scoping rules.

From this foundation, you will explore functions, a crucial aspect of any programming language, including considerable sophistication in defining parameters to a function and providing argument values. Explore advanced functional programming using generator expressions, comprehensions, and generator functions. Handle file input and output using web services and context managers, exception handling and explore wider, popular frameworks.

Through this concise and practical guide, you will explore all you need to know to leverage this powerful, and industry-standard, programming language.

What you will learn

• Use Python interactively and master the art of writing efficient Python scripts
• Learn techniques for working with string data, including how to use regular expressions to parse strings
• Get to know how the short-circuit and if-else logic operators work
• Explore mutable data structures including list, set, and dict
