Python is a widely used, interpreted, object-oriented, and high-level programming language with dynamic semantics, used for general-purpose programming. It is known for its readability, simplicity, and versatility. Here are some of the pros and cons of Python:        **Pros:**        - **Easy to learn:** Python is known for its simple and intuitive syntax, making it easy for beginners to learn. It has a relatively shallow learning curve compared to other programming languages.        - **Versatile:** Python is a general-purpose programming language, meaning it can be used for a wide variety of tasks, including web development, data science, machineUsing in a chain‚Äãfrom langchain.prompts import PromptTemplatetemplate = """Question: {question}Answer: Let's think step by step."""prompt = PromptTemplate.from_template(template)chain = prompt | llmquestion = "Who was the president in the year Justin Beiber was born?"print(chain.invoke({"question": question}))     Justin Bieber was born on March 1, 1994.
