Tool usage (function calling) in Prompt Engineering / GenAI - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to call the function that generates text from a prompt.

Prompt Engineering / GenAI

response = generate_text([1])

Drag options to blanks, or click blank then click option'

A12345

B"Hello, world!"

CNone

Dgenerate_text

Attempts:

3 left

💡 Hint

Common Mistakes

Passing a number instead of a string.

Passing None instead of a string.

Passing the function name itself instead of a string.

The function generate_text expects a string prompt as input, so passing "Hello, world!" is correct.

2fill in blank

medium

Complete the code to call the function with the correct keyword argument for temperature.

Prompt Engineering / GenAI

result = generate_text(prompt="Hi", [1]=0.7)

Drag options to blanks, or click blank then click option'

Atemperature

Btemp

Ctemp_value

Dtempurature

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'temp' instead of 'temperature'.

Misspelling 'temperature' as 'tempurature'.

Using a non-existent keyword like 'temp_value'.

The correct keyword argument for controlling randomness is 'temperature'.

3fill in blank

hard

Fix the error in calling the function to generate text with max tokens set to 50.

Prompt Engineering / GenAI

output = generate_text(prompt="Test", max_tokens=[1])

Drag options to blanks, or click blank then click option'

Afifty

B"50"

C50

DNone

Attempts:

3 left

💡 Hint

Common Mistakes

Passing max_tokens as a string "50".

Passing a word like 'fifty' instead of a number.

Passing None instead of a number.

max_tokens expects an integer, so 50 without quotes is correct.

4fill in blank

hard

Fill both blanks to call the function with prompt and stop sequence arguments.

Prompt Engineering / GenAI

response = generate_text(prompt=[1], stop=[2])

Drag options to blanks, or click blank then click option'

A"Hello"

B"\n"

C"END"

DNone

Attempts:

3 left

💡 Hint

Common Mistakes

Using None for prompt or stop.

Using 'END' as stop when newline is expected.

Passing prompt without quotes.

The prompt should be a string like "Hello" and the stop sequence is often a newline character "\n".

5fill in blank

hard

Fill all three blanks to call the function with prompt, temperature, and max_tokens.

Prompt Engineering / GenAI

result = generate_text(prompt=[1], [2]=0.9, [3]=100)

Drag options to blanks, or click blank then click option'

A"Write a poem"

Btemperature

Cmax_tokens

Dprompt

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'prompt' as a keyword argument again.

Passing temperature or max_tokens as strings.

Not quoting the prompt string.

The prompt is a string, and the keyword arguments are 'temperature' and 'max_tokens'.

Practice

1. What is the main purpose of calling a function in AI tool usage?

easy

A. To perform a specific task using given inputs

B. To create new data without inputs

C. To store data permanently

D. To display the AI model architecture

Solution

1. Step 1: Understand function role in AI tools

   Functions are blocks of code designed to perform specific tasks when called with inputs.

2. Step 2: Identify the purpose of calling functions

   Calling a function means using it to do a job, usually with parameters to guide the task.

3. Final Answer:

   To perform a specific task using given inputs -> Option A

4. Quick Check:

   Function call = perform task with inputs [OK]

Hint: Functions do tasks using inputs, not just store or show data [OK]

Common Mistakes:

• Thinking functions create data without inputs
• Confusing function calls with data storage
• Assuming functions only display info

2. Which of the following is the correct way to call a function named generate_text with a parameter prompt in Python?

easy

A. generate_text = prompt

B. generate_text->prompt()

C. call generate_text(prompt)

D. generate_text(prompt)

Solution

1. Step 1: Recall Python function call syntax

   In Python, functions are called by writing the function name followed by parentheses enclosing parameters.

2. Step 2: Match syntax with options

   generate_text(prompt) uses the correct syntax: function name followed by parentheses with parameter inside.

3. Final Answer:

   generate_text(prompt) -> Option D

4. Quick Check:

   Python function call = name(params) [OK]

Hint: Use functionName(parameters) to call in Python [OK]

Common Mistakes:

• Using assignment (=) instead of call
• Adding extra keywords like 'call'
• Using wrong symbols like '->'

3. Given the code:

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

result = add_numbers(3, 5)
print(result)

What will be printed?

medium

A. None

B. 8

C. TypeError

D. 35

Solution

1. Step 1: Understand function behavior

   The function add_numbers takes two inputs and returns their sum.

2. Step 2: Calculate the sum of inputs 3 and 5

   3 + 5 equals 8, so the function returns 8, which is stored in result.

3. Final Answer:

   8 -> Option B

4. Quick Check:

   3 + 5 = 8 [OK]

Hint: Add inputs inside function to get output [OK]

Common Mistakes:

• Concatenating numbers as strings (35)
• Expecting error due to parameters
• Ignoring return value (None)

4. Identify the error in this function call:

def translate(text, language):
    return f"{text} in {language}"

result = translate("Hello")
print(result)

medium

A. Return statement syntax error

B. Function name is incorrect

C. Missing second argument 'language' in function call

D. Print statement is missing parentheses

Solution

1. Step 1: Check function definition parameters

   The function translate requires two parameters: text and language.

2. Step 2: Check function call arguments

   The call translate("Hello") provides only one argument, missing the second required parameter.

3. Final Answer:

   Missing second argument 'language' in function call -> Option C

4. Quick Check:

   All parameters must be given when calling [OK]

Hint: Count parameters in definition and match in call [OK]

Common Mistakes:

• Ignoring missing arguments
• Assuming default values without definition
• Misreading function name or print syntax

5. You want to use a function summarize_text that takes a long text and a number max_length to limit summary size. Which call correctly uses this function to summarize article with a max length of 100?

hard

A. summary = summarize_text(article, max_length=100)

B. summary = summarize_text(max_length=100, article)

C. summary = summarize_text(article max_length=100)

D. summary = summarize_text(article, 100, max_length)

Solution

1. Step 1: Understand function parameters and calling conventions

   The function expects two inputs: the text and the max_length number. Keyword arguments can be used to specify parameters by name.

2. Step 2: Identify correct syntax for positional and keyword arguments

   summary = summarize_text(article, max_length=100) correctly passes article as the first argument and uses max_length=100 as a keyword argument.

3. Final Answer:

   summary = summarize_text(article, max_length=100) -> Option A

4. Quick Check:

   Positional first, then keyword args [OK]

Hint: Use positional args first, then named args [OK]

Common Mistakes:

• Placing keyword argument before positional
• Missing commas between arguments
• Adding extra unexpected arguments
