The lecture demonstrates PHP file input and output using two scripts: writing data to a new file and reading it back line by line.

Explore PHP 7 scalar type declarations, enforcing argument and return types. See coercive mode auto-convert strings to integers and strict mode raise fatal errors with declare(strict_types=1).

Discover PHP 7's null coalescing operator, using ?? to check whether a variable is set and provide a default when not, replacing the ternary operator.

Explore the PHP spaceship operator, introduced in PHP 7, a three-way comparison that returns -1, 0, or 1 for left and right operands across numbers, floats, and strings.

Explore polymorphism in PHP by implementing interfaces and abstract classes, showing how concrete classes override interface methods and abstract methods to perform tasks like button clicks and area calculations.

Explore Python bitwise operators by applying and, or, xor, and the complement (~) with 60 and 213 to show results 12, 61, 49, -61, 240, and 15.

Explore Python identity operators is and is not, which compare whether two variables reference the same object in memory, using the built-in id function.

Learn how to create and use Python list objects with square brackets, containing elements of different types such as strings, numbers, and complex numbers, and how quotes influence string elements.

Explore Python list basics by performing indexing, slicing, repetition using the star operator, and concatenation with the plus operator to manipulate and combine list objects.

Learn how to use Python list methods like count, extend, index, insert, pop, remove, reverse, and sort to modify and query lists, including handling missing elements.

Explain Python tuples, showing index and slice access, immutability that blocks item assignment and element deletion, and creating new tuples by joining and deleting the whole tuple.

Learn how to access, update, add, and delete items in Python dictionaries using key-based access with square brackets, and use del, clear, and error handling.

Demonstrate Python's string formatting operators using the percent syntax to substitute values like a name X-Y-Z and age 25, with integers, floats, octal, hexadecimal, and scientific notation.

Explore Python 3 encode and decode functions for strings using the base64 module to convert strings to binary-encoded bytes and back to their original form.

Explore how Python defines strings using single, double, and triple quotes, including multiline strings. See examples showing single quotes, double quotes, and triple quotes producing strings across lines.

Explore Python string literals with triple quotes, including triple single and triple double forms, and learn how escape sequences and non printable characters like tab and newline displayed verbatim.

Explore how the Python if statement controls a 10 percent discount: read amount via input, convert to int, apply discount if amount exceeds 1000, then print the net amount.

Explore how to implement Python if-else statements to calculate discounts based on an amount, applying 10 percent for amounts over 1000 and 5 percent otherwise, with a zero-initialized discount variable.

Explore python if, elif, and else statements to implement a tiered discount based on input amount, with 10% for amounts over 1000, 5% for 500–1000, and zero otherwise.
