Python Programming for Beginners

Compare editors and IDEs across Windows, Linux, and macOS, from Notepad and vi to VS Code, Eclipse, and PyCharm, then set up Python development on Ubuntu with Python 3.x.

Trace the history of python from its 1991 release to major 2.x and 3.x milestones, migration needs from python 2 to 3, and notable 3.5 and 3.8 releases.

Learn to comment Python code using three methods: single line with #, inline comments, and multi-line blocks with triple quotes; see practical examples.

Explore python.org to download the latest version of Python, access documentation and tutorials, and learn the language and library references, including the math library power function and online help.

Explore built-in data types in Python, including integers, floats, lists, tuples, strings, dictionaries, sets, and file objects, with emphasis on mutability and immutability, true/false booleans, and None.

Explore Python operators, including automatic operators, comparison operators, assignment operators, logical operators, bitwise operators, membership operators, and identity operators, with hands-on examples in the REPL environment.

Master bitwise operators in binary—and, or, xor, complement, left shift, and right shift—through 21 and 25 examples with results like 17, 29, 12, -22, 84, and 5.

Apply and refine if statements and nested if blocks in Python using a score variable to handle conditions like less than 100, equal to 100, and greater than 200.

Explore the Python while loop by defining a condition that remains true to keep executing statements, and exit the loop when the condition fails.

Discover how the Python for loop iterates over a list of items with for x in ..., processing each element—numbers or strings—and ends when the list is exhausted.

Learn to extract sublists with index ranges, understand end-exclusive slicing, use negative indices, and locate items with index() while optionally narrowing searches with start and end bounds.

Learn to manipulate Python lists by appending, extending, and inserting items. Then update specific elements by index or replace a range, and concatenate lists with the plus operator.

Explore how to copy lists in Python using assignment or the copy method. Compare aliasing with independent copies to see how changes propagate.

Learn how to count occurrences and find the index of items in lists and tuples, using the membership operator and a for loop to iterate.

Explore membership operators for Python sets, using in and not in to check elements like Kim. Iterate through set items, noting sets have no index and are unordered.

Explore Python sets and built-in functions including all, any, len, max, min, and sorted, with practical examples of true/false values, empty sets, and type handling.

Explore common Python string methods for validation, case conversion, whitespace handling, alignment, and presence checks (isalpha, isdigit, islower, isupper, startswith, endswith), with practical examples.
