💡 Hint

Common Mistakes

Forgetting the curly braces around the variable name.

Using the variable name without braces.

Using incorrect variable names.

The placeholder in an f-string must be enclosed in curly braces, so {user_name} is correct.

2fill in blank

medium

Complete the code to create a prompt template that asks for a topic and includes it in the prompt.

Prompt Engineering / GenAI

template = "Write a short paragraph about [1]."

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

A{topic}

Btopic

C<topic>

D[topic]

💡 Hint

Common Mistakes

Using brackets or angle brackets instead of curly braces.

Not using any braces around the variable name.

The placeholder must be enclosed in curly braces to be replaced by the variable 'topic'.

3fill in blank

hard

Fix the error in the prompt template code to correctly insert the variable 'question'.

Prompt Engineering / GenAI

prompt = f"Please answer the following: [1]"

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

A{question}

Bquestion

C"question"

D'question'

💡 Hint

Common Mistakes

Including extra curly braces.

Putting quotes around the variable name inside the braces.

In an f-string, the variable name should be inside single curly braces without quotes, so 'question' is correct.

4fill in blank

hard

Fill both blanks to create a prompt template that asks for a user's name and favorite color.

Prompt Engineering / GenAI

template = "Hello, [1]! Your favorite color is [2]."

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

A{name}

Bname

C{color}

Dcolor

💡 Hint

Common Mistakes

Using variable names without braces.

Using braces without variable names.

Mixing braces and no braces.

Placeholders must be enclosed in curly braces, so {name} and {color} are correct.

5fill in blank

hard

Fill all three blanks to build a prompt template that asks for a user's name, age, and city.

Prompt Engineering / GenAI

template = "Name: [1], Age: [2], City: [3]."

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

A{user_name}

B{user_age}

C{user_city}

Duser_info

💡 Hint

Common Mistakes

Using variable names without braces.

Using a single variable for all placeholders.

Forgetting braces on one or more placeholders.

Each placeholder must be enclosed in curly braces with the correct variable name.

Practice

1. What is the main purpose of using prompt templates in AI interactions?

easy

A. To train new AI models from scratch

B. To reuse question formats and save time

C. To store large datasets efficiently

D. To improve hardware performance

Solution

1. Step 1: Understand the role of prompt templates

   Prompt templates are designed to create reusable question formats for AI, making interactions faster and more consistent.

2. Step 2: Compare options with the purpose

   Only To reuse question formats and save time correctly describes this purpose; others relate to unrelated AI tasks.

3. Final Answer:

   To reuse question formats and save time -> Option B

4. Quick Check:

   Prompt templates = reuse formats [OK]

Hint: Templates reuse question formats to save time [OK]

Common Mistakes:

• Confusing prompt templates with model training
• Thinking templates store data
• Assuming templates improve hardware

2. Which of the following is the correct way to create a prompt template in Python using curly braces?

easy

A. template = "What is the capital of {}?".format('France')

B. template = "What is the capital of []?".format('France')

C. template = "What is the capital of {}?".replace('France')

D. template = "What is the capital of ()?".format('France')

Solution

1. Step 1: Identify correct placeholder syntax

   Curly braces {} are used as placeholders in Python strings for the format() method.

2. Step 2: Check method usage

   Only template = "What is the capital of {}?".format('France') uses curly braces with format() correctly; others use wrong brackets or methods.

3. Final Answer:

   template = "What is the capital of {}?".format('France') -> Option A

4. Quick Check:

   Curly braces + format() = correct syntax [OK]

Hint: Use curly braces {} with format() for templates [OK]

Common Mistakes:

• Using square or round brackets instead of curly braces
• Using replace() instead of format()
• Forgetting to call format()

3. What will be the output of the following code?

template = "Hello, {}! Today is {}."
filled = template.format('Alice', 'Monday')
print(filled)

medium

A. Hello, Alice! Today is {}.

B. Hello, {}! Today is {}.

C. Error: format() missing arguments

D. Hello, Alice! Today is Monday.

Solution

1. Step 1: Understand the template string

   The string has two placeholders {} to be replaced by format() arguments.

2. Step 2: Apply format() with two arguments

   Arguments 'Alice' and 'Monday' replace the placeholders in order.

3. Final Answer:

   Hello, Alice! Today is Monday. -> Option D

4. Quick Check:

   format() fills placeholders in order [OK]

Hint: format() fills {} placeholders in order [OK]

Common Mistakes:

• Printing template without calling format()
• Using fewer arguments than placeholders
• Confusing placeholder order

4. Identify the error in this prompt template code:

template = "What is your favorite color, {name}?"
filled = template.format()
print(filled)

medium

A. print() function is missing parentheses

B. Incorrect placeholder syntax, should use []

C. Missing argument for placeholder 'name' in format()

D. format() cannot be used with strings

Solution

1. Step 1: Check placeholder usage

   The template has a named placeholder {name} that requires a matching argument in format().

2. Step 2: Analyze format() call

   format() is called without any arguments, so the placeholder cannot be replaced, causing an error.

3. Final Answer:

   Missing argument for placeholder 'name' in format() -> Option C

4. Quick Check:

   Named placeholders need matching format() arguments [OK]

Hint: Named placeholders require matching format() arguments [OK]

Common Mistakes:

• Using wrong brackets for placeholders
• Thinking format() can't be used with strings
• Forgetting to pass arguments to format()

5. You want to create a prompt template that asks for a user's name and age, but only include the age part if the age is provided (not None). Which template and code snippet correctly achieves this?

hard

A. template = "Hello, {name}!{age_part}"
age_part = f" You are {age} years old." if age is not None else ""
filled = template.format(name=name, age_part=age_part)

B. template = "Hello, {name}! You are {age} years old."
filled = template.format(name=name, age=age if age else '')

C. template = "Hello, {name}! You are {age} years old."
filled = template.format(name=name)

D. template = "Hello, {name}!{age_part}"
age_part = " You are {age} years old." if age else ""
filled = template.format(name=name, age_part=age_part)

Solution

1. Step 1: Understand conditional inclusion

   We want to add the age part only if age is not None, so we prepare age_part accordingly.

2. Step 2: Check template and format usage

   template = "Hello, {name}!{age_part}" age_part = f" You are {age} years old." if age is not None else "" filled = template.format(name=name, age_part=age_part) correctly creates age_part with age value if not None, else empty string, then formats template with both parts.

3. Final Answer:

   template = "Hello, {name}!{age_part}" age_part = f" You are {age} years old." if age is not None else "" filled = template.format(name=name, age_part=age_part) -> Option A

4. Quick Check:

   Use conditional string parts with format() [OK]

Hint: Use conditional strings for optional template parts [OK]

Common Mistakes:

• Passing None directly causing 'None' string output
• Not defining age_part before format()
• Forgetting to handle missing age gracefully
