Coding Skills for Job Seekers

Explore Replit, a browser-based platform to run code in many languages, and sign up via email or Google/GitHub to set up a Python workspace and start coding.

Write your first Python line with the print function to display text, for example print("Hello, world"). Run the program to see the output and use comments to improve readability.

Declare variables in Python by choosing a name and using the assignment operator to assign a value. Python is dynamically typed and variable names start with a letter or underscore.

Explore declaring integer variables in Python, representing whole numbers (positive or negative), and performing addition, subtraction, multiplication, and division with notes on integer versus floating point results.

Learn how Python strings concatenate with the plus operator, form full names from first and last names, print results, and see how quoted numbers become strings.

Explore floats vs integers in Python, highlighting decimal precision for measurements. Use examples like temperature, pi and radius, and circle area to show type promotion.

Learn to get user input in Python with the input function, prompting for a name, storing it in a variable, and using the returned string.

Explore how booleans control program flow in Python, using true/false literals in conditions, if/else statements, and basic comparisons.

Coding skills for job seekers teaches you to use a while loop to repeat code, print values, and increment a counter to avoid infinite loops.

Explore for loops across lists, strings, ranges, and integers, using the range function to repeat a message like hello world from 0 to 4 and 2 to 5.

Explore nested loops in Python using for loops and range to print an asterisk pattern, showing how outer and inner loops control rows and stars, and when nesting hurts readability.

Explore dictionaries, a data structure using key value pairs to store and retrieve data, update values, add keys with lists, and use built in methods to manipulate data types.

Learn how constants represent fixed values in code, illustrated by pi and the circle area calculation. Understand how Python's uppercase convention signals immutability, improving readability and centralizing updates.

Learn how functions organize code into reusable blocks, making programs more readable and maintainable. Call a function to run its code, as demonstrated by printing hello world.

Explore the scope of variables, distinguishing local and global visibility inside functions and across the program, and learn how scope avoids errors and supports clean code organization.

Define advanced functions with parameters to accept different inputs and perform actions accordingly. Call functions with arguments to produce personalized greetings and reusable, data-driven behavior.

Explain how to use modules in Python by importing the math module and computing a circle's area from a radius with math.pi and math.pow.

Learn to use the randint function from the random module to generate an inclusive 1 to 100 random number in Python for simulations and games.

Explore recursion, a programming technique where a function calls itself to break problems into smaller subproblems, with a base case and a recursive case demonstrated by a count down.

Explore how the modulo operator (the percentage symbol) computes remainders, as shown by ten modulo three and checking even or odd numbers like seven, demonstrating range wrapping and divisibility.

Debug Python code in Replit by identifying a zero division error in a simple divide function. Apply a safe fix and validate with tests for stable code.
