Unable to add column to a DF: NameError: name 'lit' is not defined

Hello,

I am accessing a hive table through spark from jupyter.
I have created a DF and its showing the data of table in DF.

Now I want to add a column to the df.
I’m trying the following code but its throwing error.

df2 = df.withColumn(“Marks”, lit(‘test’))
df2.show()


NameError Traceback (most recent call last)
in
----> 1 df2 = df.withColumn(“marks”, lit(‘test’))
2 df2.show()

NameError: name ‘lit’ is not defined

Please help.

What is lit? Have you defined a function?
