Hadn't thought this before. But.

>>> a = 2  
>>> a′ = a + 1  
 File "<stdin>", line 1  
 a′ = a + 1  
 ^  
SyntaxError: invalid character '′' (U+2032)

The Unicode Prime (and Double Prime) should be valid parts of an identifier. Maybe a few others that are widely-used.

>>> a² = a ** 2  
 File "<stdin>", line 1  
 a² = a ** 2  
 ^  
SyntaxError: invalid character '²' (U+00B2)

@slott56 Don't think so. Will break ABI compatibility with C and C++ identifiers. Although ABI stability is kind of a foreign word for the Python guys.

How does one type 0-9 superscript...

@mrblissett @slott56 it depends on your OS or terminal emulator, but there’s typically a way to enter any character if you know the Unicode code point (U+00B2).

https://en.wikipedia.org/wiki/Unicode_input

Many times, I just copy-and-paste.

@cohomologyisFUN @slott56
My point is:
** is faster to remember type than any unicode input method.
No lookups, no Alt+ codes, no editor keyboard shortcut, no copying from a map.

Use * twice, be done, and move on!

@mrblissett @slott56 sorry, I was dense and failed to recognize your question as rhetorical 😀🤦🏽‍♂️

I agree, but I think OP’s point was to see which characters are allowed (or not) in identifiers
