Python Fundamentals

Master Python fundamentals from environment setup to writing your first program. Learn data types, inputs, strings, type conversion, arithmetic, operators, loops, and lists, with coding challenges.

Set up a Python environment on macOS by downloading Python from python.org, installing it, and installing the PyCharm community edition for Intel or Apple silicon, then finish initial setup.

Download the latest Python from python.org and install with add to path, then install PyCharm Community Edition and complete the first run by skipping settings import and allowing access.

Create your first Python project named Helloworld, explore the project window and virtual environment, add a Python file, and run to print hello world in the terminal.

Explore how Python variables store data in memory, assign values like 9.99 or 49.75, and print them using the print function, with strings in quotes and booleans True or False.

Write a simple Python program to store a name, age, and address in variables and print them on the terminal; next, learn about taking user inputs.

Learn how to read user input in Python using the input function, assign it to a variable, and print or concatenate strings to customize output.

Explore type conversion in Python by turning user input from string into integers to perform addition, using int() and other built-in functions like float(), bool(), and str().

Build a simple age calculator in python by inputting your birth year, computing the age with the current year from the time module, and printing the result.

Explore Python strings as objects, calling methods like upper, lower, find, index, and replace; see how these operations return new strings and do not modify the original, with zero-based indexing.

Explore arithmetic operations in Python, including addition, subtraction, multiplication, division with slash for floats and double slash for integers. Learn modulus, exponent, and augmented assignment such as x += 5.

This lecture guides you to take two user inputs, convert them to integers, print outputs, and perform addition, subtraction, multiplication, division (with and without decimals), and modulo.

Analyze operator precedence in Python with an expression that yields 13, then 18 using parentheses. Learn how parentheses change evaluation order and preview comparison operators.

Explore how comparison operators evaluate values and produce booleans, including greater than, greater than or equal to, less than, less than or equal to, and not equal to.

Learn to make decisions in Python using if, elif, and else with comparison operators. See a marks example that prints grades, handles multiple conditions, and demonstrates indentation and otherwise outcomes.

Build a simple Python program that checks if a number is even or odd by taking user input, converting to int, and using modulo two to print the result.

Explore logical operators in Python fundamentals by evaluating price between 40 and 60 with and, and apply or to test if a boolean expression is true.

Write a Python program that checks loan eligibility by ensuring age at least 18 and income at least 15000 using int input and an if statement that prints the decision.

Learn to use a while loop to repeat code, control iterations with a condition, and increment a counter to print numbers from 1 to 10, 1000, or even 10 million.

Learn to declare a Python list of student names, print it, and access elements with zero-based and negative indices. Update elements by index and slice lists, noting indices are exclusive.

Explore Python list methods on a name list, including append to add at the end, insert for a given index, remove and clear, and the in keyword to check existence.

Master how to use a for loop in Python to iterate over a list and print each item on a separate line, using a loop variable to hold values.

Complete the final python fundamentals challenge by writing a program that sums all items in the number list using a for loop, a total variable, and the augmented assignment operator.
