SyntaxError: Python keyword not valid identifier in numexpr query about skope-rules

[ngoix]

is it because you put = in your feature names?

@osdiego Did you copy and paste from another document. The "-3" is not being read correctly by the query function. Try removing/deleting the minus and replacing it. Let me know if this works.

I see, I think that might be the issue.
But what is causing this issue? Is there any workaround for it?

[ngoix]

the variable names are parsed to build the rules, which causes your bug.
I don't see an easy workaround. You really shouldn't put = in your feature names...

Feature names are strings, so it seems like a limitation to restrict what they can contain (everything else in the scikit-learn world doesn't care about it). Maybe it should be allowed, or at least documented somewhere?

[ngoix]

you are right this should be documented. Feel free to open a PR for that or for fixing the syntax error :)

Guys, I too get the similar error, when I run the below command, if I remove the pipe, it works with only one condition

SyntaxError: Python keyword not valid identifier in numexpr query

Error is --- train_outliers = train.query('age_z > 3 | age_z < ‐3')

This happened to me as well. The problem was that I kept holding down the alt-key when writing the following the pipe symbol. I encounter this frequently, as writing pipe requires me to hold alt.

Happened to me too, do anyone know how to fix?! Thanks xD

@CCNOAI I'm doing something like: (importance >= 0 | importance = -7).
The question is: I need to search like that, is there no way?
