[hexarobi]

What is the current behavior?

An error when running under Python 3.14

AttributeError: 'super' object has no attribute '_expr_id' and no __dict__ for setting new attributes
https://github.com/snowflakedb/snowpark-python/blob/main/src/snowflake/snowpark/_internal/analyzer/expression.py#L162

What is the desired behavior?

Successful run under Python 3.14

How would this improve snowflake-snowpark-python?

Enables snowpark usage with most current and performant Python.

Hi @hexarobi ,

Thanks for raising the issue, the support with python 3.14 for snowflake-snowpark-python is not yet added.
Once its added, it will work.
