Multiline f-strings

多行字符串使用fstring需要注意每行都要加fstring

>>> name = "Eric"
>>> profession = "comedian"
>>> affiliation = "Monty Python"
>>> message = (
...     f"Hi {name}. "
...     f"You are a {profession}. "
...     f"You were in {affiliation}."
... )
>>> message
'Hi Eric. You are a comedian. You were in Monty Python.'

如果使用三个双引号

>>> message = f"""
...     Hi {name}. 
...     You are a {profession}. 
...     You were in {affiliation}.
... """
...
>>> message
'\n    Hi Eric.\n    You are a comedian.\n    You were in Monty Python.\n'
