[issue30858] Keyword can't be an expression?

Lysandros Nikolaou added the comment: I like the current error message. What bugs me a little is the position of the caret, which I think is a bit misleading. Guido, Pablo, should we move the caret to point at the `=` sign or whatever comes after it? I think I prefer the former. --

Irit Katriel added the comment: I get this now on 3.10: >>> print(end1 + end2 + end3 + end4 + end5 + end6 + end=' ') File "", line 1 print(end1 + end2 + end3 + end4 + end5 + end6 + end=' ') ^ SyntaxError: expression cannot contain assignment, perhaps you meant "=="?

[issue30858] Keyword can't be an expression?

Vedran Čačić added the comment: Nick, thanks for validating my pain. :-| In the meantime, I found out Python already knows more finely what kind of expression something is, and uses that knowledge in the error messages. Look: >>> a + b = 4 SyntaxError: can't assign to operator

[issue30858] Keyword can't be an expression?

Nick Coghlan added the comment: The current error message is also outright incorrect, since simple names *are* valid expressions - the actual problem being reported is that binary expressions (veky's case) and strings (my case) *aren't* identifiers. --

[issue30858] Keyword can't be an expression?

Nick Coghlan added the comment: I just ran into this, and found the existing error message *incredibly* confusing. My immediate reaction was "There's no keyword in that line, what are you complaining about?". An error message that said "Keyword argument name must be an identifier" would

Raymond Hettinger added the comment: FWIW, I prefer the current error message and my students don't seem to have issues with it. No matter what wording we put in, someone will always find a way to misread it, in part because the "end6 + end=' '" example isn't a simple mistake, it reflects

[issue30858] Keyword can't be an expression?

R. David Murray added the comment: If I saw your message, I would think "what is a 'simple name'?". There's no glossary entry for that, nor is it a concept used elsewhere in the documentation as far as I remember. One could instead use "single identifier", but the problem with both of

[issue30858] Keyword can't be an expression?

Vedran Čačić added the comment: I agree it's more _correct_. But it's also more confusing. As far as I can tell, when writing error messages, we tend to minimize confusion, not maximize correctness. Of course, it would be great to have both. Your "keyword argument name" seems pretty good.

[issue30858] Keyword can't be an expression?

R. David Murray added the comment: I think the current error message is more informative than your suggestion, myself. However, the message could say "keyword argument name" instead of just "keyword", which I think would be quite a bit clearer. I seem to remember another discussion where I

[issue30858] Keyword can't be an expression?

New submission from Vedran Čačić: Look at this (from https://www.quora.com/Is-end1-a-keyword-in-Python-3-6-1): print(end1 + end2 + end3 + end4 + end5 + end6 + end=' ') ^ SyntaxError: keyword can't be an expression Wouldn't it be better if the message said "keyword for an argument must
