fireld列表中的未知列-mysql python连接器插入

在这段代码中，我得到以下错误：

    c.execute('show tables')
    for i in c:
        print(i)
    t=input('enter exact table name')
    n=0
    c.execute('show columns from {}'.format(t))
    records=c.fetchall()
    print(records)
    for i in records:
        n=n+1
    a=1
    data=''
    while a!=0:
        for i in range(n):
            v=input("enter data")
            if i==n-1:
                data=data+v
            else:
                data=data+v+','
        print(data)
        print('insert into {} values{}'.format(t,data))
        c.execute('insert into {} values({})'.format(t,data))

有谁能帮我避免这个错误吗 我还确保只有一个表，这就是我正在插入的表

这是我得到的输出，包括输入值：

数据周围缺少引号

所以MySQL认为subru不是一个名字。相反，他认为这是一个列名

>>>('hellopython',)
>>>enter exact table namehellopython
>>>[('student', b'varchar(30)', 'YES', '', None, ''), ('rollno', b'varchar(30)', 'YES', '', None,'')]
>>>enter datasubru
>>>enter data29
>>>(subru,29)
>>>insert into hellopython values(subru,29)

你能解释一下你在这里想要实现什么，你的预期产出是什么吗？

if i==n-1:
    data=data+"'"+v+ "'"
else:
    data=data+"'"+v+ "'"+','
print(data)
print('insert into {} values{}'.format(t,data))
c.execute('insert into {} values({})'.format(t,data))
