python - 比较python中的日期

我正在尝试比较 python 中的日期。谁能告诉我为什么这行不通。

 cursor = conn.cursor()

 tech = raw_input("Please enter your id number: ")

 cursor.execute("Select cust_id from client where tech_id = %s" % tech)
 rows = cursor.fetchall()
 day_num = datetime.datetime.today().weekday()


 dte = datetime.datetime.today()
 week = datetime.timedelta(days=5)
 service_inc = datetime.timedelta(days=14)
 friday = dte + datetime.timedelta(days=5)
 work = []
 for row in rows:
     client = row[0];
     cursor.execute("Select last_serviced from client where " \
     "cust_id= %s" % client)
     ser_date = cursor.fetchone()
     ser_date = ser_date[0] + service_inc
     if dte <= ser_date <= friday:
         work.append(client)

我不断收到的错误是无法将 datetime.datetime 与 datetime.date 进行比较。提前感谢您的帮助。

最佳答案

看起来像是类型错误。
