The correct method to write a single row is writerow.

4fill in blank

hard

Fill both blanks to open a CSV file and write a header row.

Raspberry Pi

with open('log.csv', [1], newline=[2]) as file:
    writer = csv.writer(file)
    writer.writerow(['date', 'value'])

Drag options to blanks, or click blank then click option'

Using read mode 'r' or setting newline to True.

Open the file in write mode ('w') and set newline to '' to avoid extra blank lines on Windows.

5fill in blank

hard

Fill all three blanks to write multiple rows to a CSV file using a loop.

Raspberry Pi

with open('data.csv', [1], newline=[2]) as file:
    writer = csv.writer(file)
    for [3] in range(3):
        writer.writerow([f'Day {i+1}', i*10])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using append mode instead of write, omitting newline='' causing blank lines, or wrong loop variable.

Open the file in write mode ('w'), set newline to '', and use 'i' as the loop variable.
