LangChain - Fundamentals

Given this code snippet, what will be the output?

from langchain import PromptTemplate, LLMChain

prompt = PromptTemplate(template="What is the capital of {country}?")
chain = LLMChain(prompt=prompt)
result = chain.run(country="France")
print(result)

A"Paris"

BAn error because LLM is missing

C"What is the capital of France?"

D"France"

Step-by-Step Solution

Solution:

Step 1: Analyze the code components
The chain is created with a prompt but no LLM (language model) is provided.
Step 2: Understand LangChain requirements
LLMChain needs an LLM to generate answers; missing it causes an error.
Final Answer:
An error because LLM is missing -> Option B
Quick Check:
LLM missing causes error = B [OK]

Quick Trick: LLMChain needs an LLM instance to run [OK]

Common Mistakes:

Assuming chain.run returns prompt text
Expecting output without LLM
Confusing prompt template with output
