Bug report

Bug description:

In accordance with PEP 701, the following code works:

>>> x = 1 >>> f"___{ ... x ... }___" '___1___' >>> f"___{( ... x ... )}___" '___1___'

But the following fails:

f"__{  x:d }__"

This gives:

 File "<stdin>", line 1 x:d SyntaxError: unterminated f-string literal (detected at line 2) 

Is this intended behaviour? This is not clarified in the PEP.

Similarly,

f"""__{  x:d }__"""

Gives:

Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: Invalid format specifier 'd ' for object of type 'int' 

CPython versions tested on:

3.12

Operating systems tested on:
