PromptTemplate
(
template
:
str
)
A prompt template for creating prompts with variables.
The PromptTemplate
class allows users to define a template string with
variables represented in curly braces {variable}
. The variable
names cannot contain spaces and must start with a letter or underscore,
followed by letters, digits, or underscore. These variables can be
replaced with specific values using the assemble
method, providing
flexibility in generating dynamic prompts.
Usage:
```
template_str = "Hello, {name}! Today is {day}. How are you?"
prompt_template = PromptTemplate(template_str)
completed_prompt = prompt_template.assemble(name="John", day="Monday")
print(completed_prompt)
```
