Answer 1

Step 1: split the list of 115 emails into 12 lists containing 10 emails (the last one will contain only 5).

Step 2: Iterate through the list of list and write it into csv.

def chunks(l, n):
    """Splits a list into n number of lists inside a list."""
    n = max(1, n)
    return [l[i:i+n] for i in range(0, len(l), n)]

email_list = chunks(list_of_115_emails, 10) #returns a list of list,
i = 1
for emails in email_list:
    with open(f'network_csv_{i}.csv', 'w') as f:
        writer = csv.writer(f)
        for email in emails:
            writer.writerow([email])
    i += 1
