example2:

import csv

Second_AE_Cost=[]
Second_AE_Cost.append({'emp_name': 1,  'birth_month': 10})
Second_AE_Cost.append({'emp_name': 2,  'birth_month': 20})
Second_AE_Cost.append({'emp_name': 3,  'birth_month': 30})

with open('employee_file3.csv', mode='w', newline="") as csv_file:
    fieldnames = ['emp_name', 'birth_month']
    writer = csv.DictWriter(csv_file, fieldnames=fieldnames)

    writer.writerows(Second_AE_Cost)

with open('employee_file3.csv') as csvfile:
        reader = csv.DictReader(csvfile)
        for row in reader:
            print(row['emp_name'], row['birth_month'])
