python – 从列表中删除字典

#!/usr/bin/python
import csv


def import_users(location_of_file):
    with open(location_of_file,'r',newline='',encoding='utf-8-sig') as openfile:
       reader = csv.DictReader(openfile)
       for row in reader:
            yield row

def save_csv(data,location):
   with open(location,'w',encoding='utf-8-sig') as file:
       fieldnames = ['EmailAddress','GivenName','Surname','Company','Department']
       writer = csv.DictWriter(file,fieldnames=fieldnames)
       writer.writeheader()
       for item in data:
           writer.writerow(item)



if __name__ == '__main__':
    users = list(import_users('C:TempExample.csv'))
    for user in users:
        if user['EmailAddress'] == '':
            del user
        else:
            pass
    save_csv(users,'C:TempOutput.csv')

但我的结果仍然是没有电子邮件地址的条目.我究竟做错了什么？
