Hi @Shafiul Alam​ ,

who gave those names to columns? 🙂

you can rename you columns, replace spaces / special characters, for example:

%python
import re
list_of_columns = df_corr_feats_spark.colums
renamed_list_of_columns = [ re.sub(r'[^0-9a-zA-Z]+', "_", col) for col in list_of_columns]
df_corr_feats_spark.toDF(*new_column_name_list)

thanks,

Pat
