(2,"Bhallar","20","M",3000),
(3,"Prabhu","10","M",4000),
(4,"Sandhya","10","F",2000),
(5,"Vaibhav","40","M",3500),
(6,"Amrita","50","F",2500)]
schema = ["empid","empname","deptid","gender","salary"]
empDF = spark.createDataFrame(data, schema)
#create department
dept = [("Finance",10),
("Marketing",20),
("Sales",30),
("IT",40)
]
deptschema = ["deptname","deptid"]
deptDF = spark.createDataFrame(dept, deptschema)
display(empDF)
display(deptDF)
