These placeholders can be replaced with specific values using the assemble method, providing flexibility in generating dynamic prompts.

Example 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)
```
