Prompt Templates let you dynamically build prompts from user input and other information, keeping your LLM inputs reusable and consistent.
python
from langchain.prompts import PromptTemplate
prompt_template = PromptTemplate.from_template(
"Tell me a short joke about {subject}."
)
# Create a prompt by formatting the template
prompt = prompt_template.format(subject="a cat")
print(prompt)
# This prompt can now be sent to an LLM.You should see
Tell me a short joke about a cat.
