I have two Dataframes - graph and search with the same schema Schema for graph: SCHEMA = { START_RANGE: pl.Int64, END_RANGE: pl.Int64, } Schema for search: SCHEMA = { START: pl.Int64, END: pl.Int64, } I want to search the graph dataframe. For every row in search dataframe, I want to find all the rows in the graph dataframe where the START_RANGE and END_RANGE values are strictly within the range of the search dataframe. How to achieve this using polars only? Example - graph = pl.DataFrame( { "START_RANGE": [1, 10, 20, 30], "END_RANGE": [5, 15, 25, 35], }, ) search = pl.DataFrame( { "START": [2, 11, 7], "END": [5, 14, 12], }, ) # Expected output [2,5] is in range [1,5] -> Where 2>=1 and 5<=5 [11,14] is in range [10,15] -> Where 11>=10 and 14<=15 [7,12] is not in any range output = pl.DataFrame( { "START_RANGE": [1, 10], "END_RANGE": [5, 15], }, ) Continue reading...
