Prerequisites

Before you begin, make sure you have:

A ChatGPT account or access to ChatGPT.
A working internet connection.
Basic knowledge of Python programming (helpful but not required).
Access to ChatGPT's Python code execution functionality for the execution steps.

Open ChatGPT in your web browser.

For these examples, you do not need to install Python, Visual Studio Code, or PyCharm locally if ChatGPT's Python execution feature is available.

Note: The execution controls may vary depending on your ChatGPT interface and available features. Some code blocks may offer an interactive Run button, while other workflows execute Python through ChatGPT's data analysis environment. Generating code alone does not confirm that it has been executed.

Step 1: Open ChatGPT and Start a New Chat

First, open ChatGPT and start a new conversation.

Open your preferred web browser.
Visit the ChatGPT website.
Start a new chat.
Locate the message box where you can enter instructions.

We will use this conversation to generate and execute three simple Python programs.

Step 2: Write and Run a Hello World Program

Let's begin with the simplest possible Python program: Hello World.

The goal is to ask ChatGPT to generate a Python program, execute it, and display its output.

2.1 Enter the Hello World Prompt

Copy the following prompt into ChatGPT:

Write a simple Python program that prints hello world and run the code.

Submit the prompt and examine the response.

ChatGPT generates a simple Python program using the built-in print() function.

2.2 Understand the Python Code

The following is a minimal Python implementation matching the example described in the video:

print("Hello World")

The print() function displays the specified text in the program's output.

Here, the string "Hello World" is passed to the function.

When Python executes this statement, it prints the message.

2.3 Run the Python Code Inside ChatGPT

How to Run Python Code Directly Inside ChatGPT (3 Examples)

In the video demonstration, the generated Python code appears in a code block with an option to run it.

Locate the generated Python code block.
Click the Run button shown in the demonstrated interface.
Allow the program to execute.
Examine the displayed output.

If your interface does not display a Run button, ask ChatGPT to execute the program and show its actual output. Confirm that code execution is available rather than assuming a written response represents an execution result.

2.4 Check the Output

The expected output is:

Hello World

After execution, the program displays the Hello World message.

This demonstrates the complete workflow: ask ChatGPT to generate a Python program, run the code, and inspect the result.

Step 3: Calculate the Squares of Numbers from 1 to 5

Now that we have executed a basic Python program, let's try something slightly more useful.

In this example, we will ask ChatGPT to generate a Python program that calculates the square of each number from 1 to 5.

This example introduces a fundamental Python concept: the for loop.

3.1 Enter the Python Squares Prompt

Enter the following prompt in ChatGPT:

Write a Python program to print the square of numbers from 1 to 5 and run the code.

Submit the prompt.

ChatGPT generates a Python program that uses a loop to process each number.

3.2 Understand the Python Program

Here is a simple implementation of the program described in the tutorial:

for number in range(1, 6):
    square = number * number
    print(number, square)

Let's understand how this code works.

1. The range() function

The expression range(1, 6) generates the numbers 1, 2, 3, 4, and 5. The ending value, 6, is excluded.

2. The for loop

The for loop processes each number one at a time.

3. Calculate the square

The expression number * number multiplies the current number by itself.

For example, when the number is 4:

4 * 4 = 16

4. Print the result

The print() function displays the number and its calculated square.

3.3 Run the Program

Locate the generated code block in ChatGPT and click its Run button, as demonstrated in the video.

Alternatively, use the available Python execution functionality to run the generated code.

3.4 Check the Output

For the reconstructed code above, the expected output is:

The mathematical results are:

1 squared is 1.
2 squared is 4.
3 squared is 9.
4 squared is 16.
5 squared is 25.

The exact output formatting may differ depending on the program ChatGPT generates, but the calculated values should match.

Why Is This Example Useful?

This example demonstrates how you can use ChatGPT to experiment with Python loops and quickly verify the results.

Instead of manually switching between ChatGPT and a local Python editor, you can generate code, execute it, and examine the output within the supported ChatGPT environment.

This approach is particularly helpful when learning Python syntax and testing small coding exercises.

Step 4: Create and Run a Simple Python Calculator

For our final example, let's build a simple Python calculator.

The calculator will use two numbers and perform four arithmetic operations:

Addition
Subtraction
Multiplication
Division

We will use the sample values 20 and 10.

4.1 Enter the Calculator Prompt

Copy and paste the following prompt into ChatGPT:

Create a simple Python calculator with two numbers. Perform addition, subtraction, multiplication, and division. And run the code with sample values 20 and 10.

Submit the prompt.

ChatGPT generates a Python program that performs the requested arithmetic operations.

4.2 Understand the Calculator Program

The following code is a minimal reconstruction of the calculator described in the video:

# Define two numbers
num1 = 20
num2 = 10

# Perform arithmetic operations
print("Addition:", num1 + num2)
print("Subtraction:", num1 - num2)
print("Multiplication:", num1 * num2)
print("Division:", num1 / num2)

Let's understand the program step by step.

4.3 Define Two Numbers

First, we create two variables:

num1 = 20
num2 = 10

The variable num1 stores 20, while num2 stores 10.

These values will be used for all four arithmetic operations.

4.4 Perform Addition

The addition operator + calculates the sum of two numbers.

print("Addition:", num1 + num2)

Here, 20 + 10 equals 30.

4.5 Perform Subtraction

The subtraction operator - calculates the difference between two numbers.

print("Subtraction:", num1 - num2)

Here, 20 - 10 equals 10.

4.6 Perform Multiplication

Python uses the * operator for multiplication.

print("Multiplication:", num1 * num2)

Here, 20 multiplied by 10 equals 200.

4.7 Perform Division

The division operator / divides one number by another.

print("Division:", num1 / num2)

Here, 20 divided by 10 equals 2.

Python's regular division operator produces a floating-point result for these integer operands, so the displayed value is 2.0.

4.8 Run the Calculator

After ChatGPT generates the calculator program, run the code using the execution option available in your interface.

The program performs the four operations using the sample values 20 and 10.

4.9 Check the Calculator Output

For the reconstructed Python code above, the expected output is:

Addition: 30
Subtraction: 10
Multiplication: 200
Division: 2.0

The calculator successfully performs all four operations.

The results match the calculations demonstrated in the video.

Step 5: Modify and Improve Your Python Code with ChatGPT

Once you have generated and executed a Python program, you can continue working within the same conversation.

For example, you can ask ChatGPT to modify the existing code or improve its functionality.

The general workflow is:

Describe the Python program you want to create.
Let ChatGPT generate the source code.
Run the program using the available Python execution functionality.
Check the actual execution output.
Continue the conversation to request modifications or improvements.

This workflow allows you to experiment with code without repeatedly starting from scratch.

It is particularly useful when learning Python, testing small programs, and checking programming ideas.

Summary of the Three Python Examples

Example	Python Concepts	Expected Result
Hello World	print() function	Hello World
Square Numbers	for loop, range(), multiplication	1, 4, 9, 16, 25
Simple Calculator	Variables and arithmetic operators	30, 10, 200, 2.0

Troubleshooting: Common Problems When Running Python in ChatGPT

1. The Python Code Block Does Not Have a Run Button

The Run button shown in the video may not appear in every ChatGPT interface.

If the button is unavailable, ask ChatGPT to execute the Python code and display the actual result.

Check whether your current environment supports Python execution. If execution is unavailable, you can still use ChatGPT to generate the code and run it in a local Python environment.

2. ChatGPT Generates Code but Does Not Execute It

Make sure your prompt explicitly requests execution.

For example, the Hello World prompt used in this tutorial ends with the instruction to run the code.

Also check for an actual execution result. A predicted output written in an ordinary response is not proof that the program ran.

3. The Python Output Is Different from the Expected Result

Review the generated code and confirm that the input values match those used in the tutorial.

For the calculator, the first number must be 20 and the second number must be 10.

If ChatGPT generates different input values, the results will also change.

4. The Square Numbers Program Produces an Unexpected Range

Check the range() expression.

In the reconstructed program, range(1, 6) generates the numbers from 1 through 5.

The ending value is excluded, which is why the range uses 6 rather than 5.

5. The Calculator Produces a Division Error

Division by zero is not supported in ordinary Python arithmetic.

The calculator example uses 20 and 10, so this problem does not occur.

If you modify the calculator to accept other numbers, make sure the divisor is not zero before performing division.
