def find_matching_color(existing_colors):

# Prints "What color goes well with blue, purple and white?"
print(find_matching_color(['blue', 'purple', 'white']))

{'prompt': RunnableLambda(find_matching_color)}
| PromptTemplate.from_template('{prompt}')
| model
)
runnable.invoke(['blue', 'purple', 'white'])

Prompting Utilities
join()
Formats a list of items as a natural language list.
Syntax:
join(items: Iterable, conjunction: str) -> str

pluralize()
Selects the singular or plural form of a word based on the number of items.
Syntax:
pluralize(singular: str, plural: str, items: Iterable) -> str

truncate()
Truncates a string to a maximum length. If the text is longer than the maximum
length, all characters after the maximum length are replaced with the suffix.
Syntax:
truncate(
text: str, max_length: int, mode=TruncateMode.CHARACTER, suffix="..."
) -> str
