我在这里做这段代码，我在这里得到错误的代码，元组不能在MySQL中使用？为什么呢？代码中有错误吗？
代码：
def edit():
manage = Toplevel(update)
manage.title('Manage')
#Clearing entry box
e_i_d.delete(0,END)
def edit():
#Establishing connection
con = mysql.connect(host='^^^.^^', user='user',
password='^^^^', database='DB')
# Making SQL command
sql_command = "UPDATE patient_info set `full_name`=%s ,`ph_no`=%s,`emirate_id`=%s,`email_addr`=%s,`gender`=%s,`DOB`=%s,`nationality`=%s,`blood_grp`=%s,`COVID_test`=%s,`emergency_no`=%s ;"
values = e10.get(), e20.get(), e30.get(), e40.get(), g.get(), e_dt.get(), e50.get(),b.get(),co.get() ,e60.get()
c = con.cursor()
#Executing and saving SQL command
c.execute(sql_command, (values,))
c.execute('commit')
con.close()

我猜是这里断了
这意味着
sql_command或values引起问题。您可以编写一个测试来检查values，或者为values添加一个print语句。我坚信values在某个地方有一个python元组，而不应该有一个。我希望这对你有帮助！
