By usingpandas.DataFrame.T.drop_duplicates().Tyou can drop/remove/delete duplicate columns with the same name or a different name. This method removes all columns of the same name beside the first occurrence of the column and also removes columns that have the same data with a different colu...
Duplicate rows could be remove or drop from Spark SQL DataFrame using distinct() and dropDuplicates() functions, distinct() can be used to remove rows
For stacking two DataFrames with the same columns on top of each other — concatenating vertically, in other words — Pandas makes short work of the task. The example below shows how to concatenate DataFrame objects vertically with the default parameters. Input: import pandas as pd data1 = {...

Hi I need linq query to delete the duplicate records from the datatable that contains specific words in that datacolumn. Kindly give me the solution for
df=spark.createDataFrame(data=data,schema=columns) print(df.collect()) Note:collect() action collects all rows from all workers to PySpark Driver, hence, if your data is huge and doesn’t fit in Driver memory it returns an Outofmemory error hence, be careful when you are using collect....
