How to show Polars Dataframe in PyCharm

Question

In PyCharm you have the ability to show a Pandas Dataframe with the SciView tool. Is this also possible with Polars or would I have to spam print statements?

(I also opened a PyCharm support ticket)

Answer 1

Polars DataFrames are not yet fully supported in PyCharm.

Answer 2

I've updated the jetbrains issue above with a workaround

using polars api extensions. by adding and importing the class below you can access the pandas equiv view from variable explorer provided you have pyarrow installed to run df.to_pandas()

@pl.api.register_dataframe_namespace("pd") 
class PolarsPd:
    def __init__(self, df: DF):
        self.df = df.to_pandas()

if __name__ == '__main__':
    dfpl = pl.DataFrame({'a': [1, 2, 3]})
