Python Programming for Complete Beginners

Install the current Python version on Mac, verify with python --version and pip --version, and install PyCharm Community Edition to connect the interpreter and run your first Python project.

Learn to create and declare variables in Python with a simple demo project, declaring two integers and one string, demonstrating dynamic typing and printing the variables.

Learn how the scope of variables governs access in Python, covering local and global scope and why scope matters, with simple examples.

Explore global scope in Python by creating a variable outside a function and accessing it throughout the program, with a demo that prints the value inside and outside the function.

Use the global keyword to change the value of a global variable. Explore global vs local scope with practical examples.

Discover why Python reserves keywords and cannot use them as variable names, with examples such as while, if, else, break, continue, for, from, import, and global.

Learn how identifiers name variables and functions, starting with a letter or underscore and including letters or digits. Avoid keywords and starting with digits; note invalid symbols.

Explore how Python uses operators to perform operations on variables and values, including arithmetic, assignment, and bitwise operators, with hands-on examples.

Learn how assignment operators update variables in Python, using a = 10, then a += 5, a -= 3, a *= 2, and a /= to demonstrate stepwise value changes.

Explore how Python uses and, or, and not to combine conditional statements, with practical examples showing true and false outcomes for range checks.

Explore identity operators in Python, including is and is not, and learn how to determine if variables reference the same object or different objects.

Learn how to use Python membership operators in and not in to test data structure containment in lists and sequences, with practical examples.

Explore bitwise operators on binary numbers, including and, or, xor, not, and left and right shifts, with practical examples using a = 18 and b = 11.

Learn how to use Python comments to clarify code with single-line and multi-line notes, and include details like the program’s purpose, author, and date.

Explore type conversion in Python, converting values between float and complex. Learn to use the float method and other conversion methods with examples.
