Hi,

The lit function is very handy in PySpark as it allows the developers to add a new column in the data frame.

First of all you have to import it in your PySpark program by adding following code in your python file:

from pyspark.sql.functions import lit

After that you use in following way:

df2 = df.withColumn("SomeField",lit("1"))

You can check all the usage of PySpark lit function at following tutorial page:

Hope this helps you.

Thanks
