Pyspark arraytype

I would recommend reading the csv using inferSchema = True (For example" myData = spark.read.csv ("myData.csv", header=True, inferSchema=True)) and then manually converting the Timestamp fields from string to date. Oh now I see the problem: you passed in header="true" instead of header=True. You need to pass it as a boolean, but you'll still ....

PySpark, the Python library for Apache Spark, is a powerful tool for data scientists. It allows for distributed data processing, which is crucial when dealing with large datasets. One common task that data scientists often encounter is the need to convert a StringType column to an ArrayType. This blog post will provide a step-by-step guide on how to accomplish this task in PySpark.I have a column of ArrayType in Pyspark. I want to filter only the values in the Array for every Row (I don't want to filter out actual rows!) without using UDF. For instance given this dataset with column A of ArrayType:Currently, pyspark.sql.types.ArrayType of pyspark.sql.types.TimestampType and nested pyspark.sql.types.StructType are currently not supported as output types.
