+```python
+from langchain import PromptTemplate
+
+multiple_input_prompt = PromptTemplate(
+    input_variables=["adjective", "content"], 
+    template="Tell me a {adjective} joke about {content}.",
+)
+
+# Format the prompt with only the adjective
+multiple_input_prompt.pformat(adjective="funny")
+
+# Format the prompt with the content
+multiple_input_prompt.format(content="chickens")
+# -> "Tell me a funny joke about chickens."
+```
