        writer.writeheader()
        for row in csvReader:
            requete=row[0]
            h=get_result_line(send_requete(browser,requete))

要在csv中添加头，请尝试以下代码。你知道吗

import csv
fieldnames = ["a", "b", "c", "d", "requete", "url_resultat", "url_rang"]
with open('requetetest123.csv', 'w', newline='') as csvFile:
    writer = csv.writer(csvFile, delimiter=';')
    writer.writerow(h for h in fieldnames)
