The level argument is passed to https://github.com/IAMconsortium/pyam/blob/83b75423de26e3a322dcd1ea9c61069d234f4dc8/pyam/utils.py#L417
And the docstring of the function clearly states that it can be an int or a str (like 1+
).
Fine for me to either extend the function or raise an explicit error.
Also, we should add level
to the list of illegal column names in an IamDataFrame. Using an extra-column named level would cause unexpected behavior for the filter
method.
As far as I can work out, "df.filter(level=[1, 2])" always produces nothing, even when "df.filter(level=1)" and "df.filter(level=2)" produce reasonable values. I have been using workarounds so far, but at some point we should probably fix this!
