This will try to convert any dataframe/series-like object into the Narwhals respective DataFrame/Series, while leaving the other parameters as they are. Similarly, if the output of the function is a Narwhals DataFrame or Series, it will be converted back to the original dataframe/series type, while if the output is another type it will be left as is. By setting `pass_through=False`, then every input and every output will be required to be a dataframe/series-like object. Arguments: func: Function to wrap in a `from_native`-`to_native` block. pass_through: Determine what happens if the object can't be converted to Narwhals - `False`: raise an error - `True` (default): pass object through as-is eager_only: Whether to only allow eager objects - `False` (default): don't require `native_object` to be eager - `True`: only convert to Narwhals if `native_object` is eager series_only: Whether to only allow Series - `False` (default): don't require `native_object` to be a Series - `True`: only convert to Narwhals if `native_object` is a Series allow_series: Whether to allow Series (default is only Dataframe / Lazyframe) - `False` or `None`: don't convert to Narwhals if `native_object` is a Series - `True` (default): allow `native_object` to be a Series Returns: Decorated function. Examples: Instead of writing >>> import narwhals as nw >>> def agnostic_group_by_sum(df): ... df = nw.from_native(df, pass_through=True) ... df = df.group_by("a").agg(nw.col("b").sum()) ... return nw.to_native(df) you can just write >>> @nw.narwhalify ... def agnostic_group_by_sum(df): ... return df.group_by("a").agg(nw.col("b").sum()) rrrBcHtdfd }|S)NargsrkwargsrBc2 fd|D} fd|D}fdg||RD}t|dkrd}t| |i|}t | S)Nc 8g|]}t|Srre)rargr|rzr>r{s rG zBnarwhalify..decorator..wrapper..NsI   !-) +!-    rJc @i|]\}}|t|Srr)rnamevaluer|rzr>r{s rG zBnarwhalify..decorator..wrapper..YsO    D%k!-) +!-    rJcJh|]}t|ddx S)rN)getattr)rvbs rGrzAnarwhalify..decorator..wrapper..dsG $:DAAAArJrz_Found multiple backends.
