Here's how you can do this.

import csv

header = ['a','b','c']
data = ['1','2','3','4','5','6','7','8','9']

file = csv.writer(open(f"testing.csv", "a",newline=''))
file.writerow(header)

for i in range(0,len(data),3):
    new_list = data[i:i 3]
    file.writerow(new_list)

Here's the screenshot of 'testing.csv':
