Execution Sample

AI for Everyone

def add(a, b):
    return a + b

result = add(2, '3')

This code tries to add a number and a string, which causes an error that AI can detect and suggest fixing.

Analysis Table

Step	Action	Evaluation	Result
1	Define function add(a, b)	Function created	No output
2	Call add(2, '3')	Try to add int and str	TypeError detected
3	Submit code to AI	AI analyzes code	Finds type mismatch in add function call
4	AI suggests fix	Convert '3' to int or change input	Suggestion: use add(2, int('3'))
5	Developer applies fix	Code runs add(2, 3)	Result is 5
6	Code improved	No errors	Output: 5

💡 Code runs successfully after AI-guided fix; no more errors.

State Tracker

Variable	Start	After Step 2	After Step 5	Final
a	undefined	2	2	2
b	undefined	'3'	3	3
result	undefined	error	5	5

Key Insights - 3 Insights

Why does the code cause an error at step 2?

Because it tries to add a number (2) and a string ('3'), which is not allowed. The execution_table row 2 shows the TypeError detected.

How does AI help fix the error?

AI analyzes the code and finds the type mismatch (row 3), then suggests converting the string to an integer (row 4), which the developer applies (row 5).

What happens after applying AI's suggestion?

The code runs without errors and returns the correct result 5, as shown in rows 5 and 6 of the execution_table.

Visual Quiz - 3 Questions

Look at the execution_table, what error occurs at step 2?

A NameError due to undefined variable

B SyntaxError due to missing colon

C TypeError due to adding int and str

D No error occurs

💡 Hint

Check the 'Evaluation' column in row 2 of execution_table.

At which step does AI suggest how to fix the code?

A Step 3

B Step 4

C Step 2

D Step 5

💡 Hint

Look for the row where 'AI suggests fix' action happens in execution_table.

If the developer did not convert '3' to int, what would happen to 'result' variable?

A It would cause a TypeError

B It would be 5

C It would be '23' as a string

D It would be None

💡 Hint

Refer to variable_tracker and execution_table rows 2 and 3 for error details.

Concept Snapshot

Using AI for code review and debugging:
- Write your code as usual.
- Submit code to AI tool.
- AI analyzes and finds errors or improvements.
- AI suggests fixes or improvements.
- Developer reviews and applies suggestions.
- Repeat until code runs correctly.

Full Transcript

This visual execution shows how AI assists in code review and debugging. First, a function is defined and called with mismatched types causing an error. The AI analyzes the code, detects the type mismatch, and suggests converting the string to an integer. The developer applies this fix, and the code runs successfully. Variables change from error state to correct values. Key moments highlight why the error occurs and how AI helps fix it. Quiz questions test understanding of error detection, AI suggestions, and variable states.
