How to add suffix and prefix to all columns in python/pyspark dataframe

by

Use list comprehension in python.

from pyspark.sql import functions as F

df = ...

df_new = df.select([F.col(c).alias("`"+c+"`") for c in df.columns])

This method also gives you the option to add custom python logic within the alias() function like: "prefix_"+c+"_suffix" if c in list_of_cols_to_change else c
