Getting rows that end with a certain substring in PySpark DataFrame

To get rows that end with a certain substring:


        
        
            
                
                
                    from pyspark.sql import functions as F
df.filter(F.col("name").endswith("x")).show()
                
            
            +----+---+
|name|age|
+----+---+
|Alex| 20|
+----+---+

Here, F.col("name").endswith("x") returns a Column object of booleans where True corresponds to values that end in the letter x:


        
        
            
                
                
                    df.select(F.col("name").endswith("x")).show()
                
            
            +-----------------+
|endswith(name, x)|
+-----------------+
|             true|
|            false|
|            false|
+-----------------+

We then use the PySpark DataFrame's filter(~) method to fetch rows that correspond to True.
