i have created dataframe , have 2 column names derived using labeledpoint object. problem facing whenever trying access dataframe using 'label' or 'features' column names says column object not callable

df.selectexpr("max(label) max_value","min(label) min_value"))

any suggestion of handling such dataframe appreciated

the data types of dataframe follows -
