from pyspark.sql import SparkSession
from pyspark.sql.functions import col

spark = SparkSession.builder.getOrCreate()

data = [("John", 25), ("Alice", 30), ("Bob", 35)]
df = spark.createDataFrame(data, ["Name", "Age"])
df.show()

+-----+---+
| Name|Age|
+-----+---+
| John| 25|
|Alice| 30|
|  Bob| 35|
+-----+---+

new_df = df.withColumn("NameWithSuffix", col("Name") + "_suffix")
new_df.show()

+-----+---+--------------+
| Name|Age|NameWithSuffix|
+-----+---+--------------+
| John| 25|   John_suffix|
|Alice| 30|  Alice_suffix|
