For the 'CSV and JSON in Python' workshop: Not what I expected to print

'''Python import csv

with open('teachers.csv', 'a') as csvfile: fieldnames = ['first_name', 'last_name', 'topic'] teachwriter = csv.DictWriter(csvfile, fieldnames=fieldnames)

teachwriter.writeheader()
teachwriter.writerow({
    'first_name': 'Kevin',
    'last_name': 'Lewis',
    'topic': 'Python'
})
teachwriter.writerow({
    'first_name': 'Alena',
    'last_name': 'Holligan',
    'topic': 'PHP'
})

'''
