Prompt templates in Prompt Engineering / GenAI - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a prompt template in generative AI?

A prompt template is a pre-made text structure that guides the AI to generate specific types of responses by filling in placeholders with user input or variables.

beginner

Why use prompt templates instead of writing prompts from scratch every time?

Prompt templates save time, ensure consistency, and help get better, more predictable AI outputs by standardizing how prompts are structured.

beginner

How do placeholders work in prompt templates?

Placeholders are special markers in the template that get replaced with actual input values when the prompt is used, allowing dynamic and flexible prompt creation.

beginner

Give an example of a simple prompt template for generating a story about a given animal.

Example: "Write a short story about a {animal} who goes on an adventure." Here, {animal} is the placeholder to be replaced with any animal name.

beginner

What is one key benefit of using prompt templates in AI applications?

They improve the quality and relevance of AI responses by providing clear, structured instructions that the AI can follow easily.

What does a placeholder in a prompt template do?

A Deletes unwanted words

B Generates random text

C Marks where user input will be inserted

D Changes the AI model

Placeholders mark where specific input values will be inserted into the prompt template.

Why are prompt templates useful?

A They make AI responses slower

B They help create consistent and clear prompts

C They remove the need for AI models

D They limit AI creativity

Prompt templates help create consistent and clear prompts, improving AI output quality.

Which of these is an example of a prompt template?

A "Tell me a joke about {topic}."

B "Random text without structure."

C "AI model version 3.0"

D "Delete all data"

A prompt template includes placeholders like {topic} to be replaced with user input.

What happens when you use a prompt template?

A The prompt is deleted

B The AI ignores the template

C The AI model changes automatically

D Placeholders get replaced with actual values

Using a prompt template replaces placeholders with actual input values before sending to the AI.

Which is NOT a benefit of prompt templates?

A Making AI responses unpredictable

B Ensuring consistent output

C Saving time

D Helping beginners write prompts

Prompt templates help make AI responses more predictable, not less.

Explain what a prompt template is and how it helps when working with generative AI.

Think about how a fill-in-the-blank sentence guides AI responses.

Describe how you would create a prompt template for asking the AI to write a poem about any topic.

Start with a sentence that includes a blank spot for the topic.

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
