Learn Python from Zero

Discover how variables in Python act as containers to store and print values, use the equal operator to assign data, and follow naming rules in dynamic typing language.

Explore Python data types, including integers, floats, complex numbers, strings, lists, tuples, ranges, dictionaries, sets, and booleans, and learn how they define and operate on variables.

Explore literals in Python, fixed values written in code, including numeric (integer, float, binary, octal, hexadecimal), string, boolean (true or false), null, and collection literals like list, tuple, and set.

Learn how type casting and type conversion change data types in Python, distinguishing implicit automatic conversions from explicit manual conversions and using functions like int, float, and str.

Learn how the print function in Python displays output on the screen, with examples of printing numbers, variables, and strings, and using separators, end, and f-strings.

Master arithmetic operators in Python, including addition, subtraction, multiplication, division, modulus, exponent, and floor division, and apply them to values and variables in practice.

Explore Python assignment operators, including plus equals, minus equals, multiplication equals, and division equals, with examples like x equals 5 and x plus equals 3 showing value updates.

Learn how bitwise operators work on binary numbers, including and, or, xor, and not, with practical examples like 5 and 3 and explanations of left and right shifts.

Explore Python's comparison operators, such as equal to, not equal to, greater than, less than, and greater than or equal to, which return true or false.

Explore identity operators in Python by comparing objects with is and is not, revealing when variables refer to the same memory location or distinct objects.

Master how Python's logical operators and, or, not combine conditions with practical examples like voting eligibility, day checks, and login status.

Learn how membership operators in Python use in and not in to check membership in lists or strings, with examples like Riya in students.

Learn how the Python input function captures user input as strings, and how to convert to int or float with int() and float() for arithmetic.

Learn how comments in Python explain code and aid debugging, using hash for single-line and triple quotes for multi-line comments that are ignored during execution.

Explore Python escape sequence characters, learn how backslash initiates actions like newline and tab, and print quotes or a backslash within strings through practical examples.

Master Python indentation by learning how spaces define blocks for if statements, loops, and functions, using four spaces and avoiding mixing tabs and spaces.

Master the Python if statement by testing conditions and executing code when true, using colon, indentation, and comparison operators like >=, <, and >.

Learn to use if and else statements in Python to test conditions, print results, and handle user input with type casting, including age checks and nested if statements.

Explore Python's elif statement to evaluate multiple conditions with if, elif, and else, using marks thresholds to print A, B, C grades or failed, including user input and type casting.

Explore the range function in Python and how it generates number sequences. Use start, stop, and step within for loops, including reverse order examples.

Master the Python while loop to repeat code while a condition is true, with syntax and examples like counting to five and avoiding infinite loops.

learn how match case in Python 3.10, a conditional statement that works like a switch case to compare a value against patterns and handle default cases.
