Python for Absolute beginner (Python 3 - python programming)

learn to create small Python programs that print hollow words and draw a triangle of stars, run cells, and explore the basics of Python.

Define Python variables as containers for values and print them to show dynamic text, numbers, and booleans. Explore strings, integers, floats, and booleans with examples like name, age, and is_male.

Learn to build a simple calculator in Python by defining numeric variables a and b, performing addition, subtraction, multiplication, and division, and printing results.

Learn to perform basic calculations in Python by printing sums, using absolute value, power, min, max, mean, and multi-parameter functions; convert numbers to strings and round real numbers to integers.

Explore Python strings, concatenating text with the plus operator, printing strings, and converting between strings and numbers, including case changes and handling errors when types mismatch.

Explore how strings in Python are sequences of characters, learn index positions starting at zero, and use length to access characters and the last index.

learn how to input and output values, assign a name, and print a greeting like hello name. note converting string input to a number will be covered next session.

Learn to read numeric input in Python, convert strings to int or float, and perform addition correctly instead of string concatenation, handling integers and real numbers.

Define a list to store values, access elements with zero-based and negative indexing to print first and last items, avoid out-of-range by using length minus one for the last element.

Define and manipulate lists of numbers, including integers and floats, using indexing to access elements; compare with lists of strings and apply the same operations.

Explore Python lists by creating and printing lists, sorting by values or keys, clearing and extending lists, inserting and removing elements, and using index and count to locate items.

Learn how dictionaries map keys to values in Python and print full month names by using keys like January, February, and March.

Define a function to add two numbers and print the result, reducing duplication by reusing it with pairs like 2 and 3, 5 and 6, and 4 and 8.

Define and call a Python function that greets a user by name and age and prints a message, illustrating two or three arguments.

Define a function that adds two numbers and returns the result to the main program, which then prints the value, illustrating the return value and variable scope.

Explain python if elif else with age classifier: print old if age over 60, print young if age between 20 and 60, otherwise print less than 20, using user input.

Compare multiple values with if-else logic by age and gender, including string comparisons, and print results when age is over 18 for male or female.

build an advanced calculator by taking two numbers as input, converting strings to numbers, and performing plus, minus, multiply, or divide based on user input, with an invalid operation message.

Explore boolean variables defined as values true or false, and how if statements trigger code blocks. Practice logical operators and conditions using and, or, and combined comparisons.

Learn how to use a while loop to print numbers from 1 to 10, with initialization, a condition, and proper increment. Avoid infinite loops by updating the counter.

Learn to build a Python login flow using a while loop that prompts for username and password until both are correct, then prints a success (Tom, one two three).

Learn how to use Python for loops with range to print numbers from one to ten and understand automatic incrementation.

Learn how to use a for loop to iterate over lists in Python, including range(len(list)) and printing elements. Convert integers to strings to print ages without type errors.

Learn how to open a file, select read, write, or append modes, read lines or a line with readline, and close safely in Python.

Discover how to read from and write to text files in Python, differentiate writing versus appending, and manage newlines to control content.

Learn to handle exceptions in Python with try-except, validate input by converting to integers, and display friendly messages for errors like enter a valid number or divide by zero.

Learn how comments improve readability in large codebases and team projects by explaining code sections, and note that comments are ignored by the compiler, with multi-line comments for clarity.
