The filter_out function in metadata_utils.py was using a list of tuples
to evaluate conditions. Python eagerly evaluates all tuple elements when
constructing the list, causing "input in value" to be evaluated even
when the operator is "=". When input and value are floats (after numeric
conversion), this causes TypeError: "argument of type 'float' is not
iterable".
This change replaces the tuple list with if-elif chain, ensuring only
the matching condition is evaluated.
### What problem does this PR solve?
Fixes#12285
When using comparison operators like `=`, `>`, `<` with numeric
metadata, the `filter_out` function throws `TypeError("argument of type
'float' is not iterable")`. This is because Python eagerly evaluates all
tuple elements when constructing a list, causing `input in value` to be
evaluated even when the operator is `=`.
