How to get formatted prompt?

[chengyjonathan]

Hi there!

After setting up something like the following:

prompt = PromptTemplate.from_template("Some template")
chain = LLMChain(llm=some_llm, prompt=prompt)

Is there an easy way to get the formatted prompt?

Thank you

I have the same question. What is the answer?

I found the answer in this script(https://linuxhint.com/use-langchain-llmchain-function-python/)

from langchain.prompts import PromptTemplate

from langchain.llms import OpenAI

import os

os.environ["OPENAI_API_KEY"] = "sk- Your-API-KEY”

llm = OpenAI(temperature=0.9)

prompt = PromptTemplate(

  input_variables=["Brand", "Product"],

  template="What would be the name of {Brand} that sells {Product}?",

)

from langchain.chains import LLMChain

chain = LLMChain(llm=llm, prompt=prompt)

print(chain.run({

  'Brand': "Art supplies",

  'Product': "colors"

}))

thanks Omar Farooq!
