Final answer:The 'pysparkcolumn object is not callable' error usually occurs when a PySpark column is incorrectly used as a function call. To fix this, check for syntax errors and ensure proper use of DataFrame operations and column references.Explanation:Whenencounteringthe error'pyspark column object is not callable', it typically indicates an attempt to call a PySpark column object as if it were a function rather than using it as a DataFrame column reference. PySpark columns should be used withDataFrametransformations likeselect,withColumn, orfilter. For example, an error may occur if parentheses are mistakenly used after a column name, such as df.select(col('my_column')()). Instead, it should be df.select(col('my_column')).To resolve this issue, review the code for typos or incorrect syntax. Ensure that column objects are not being called like functions, and proper DataFrame operations are being utilized. Additionally, make sure that when creating or referencing columns, you are using the appropriate functions from PySpark's sql.functions module. If these initial checks do not solve the problem, consulting the PySpark documentation or examples of DataFrame transformations can be helpful.Learn more aboutPySpark Error Resolutionhere:brainly.com/question/31585846#SPJ11...
