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. 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)
```
