code:

import sqlite3

def getstrings():
    return input().strip().split()
def getint():
    return int(input())
def getints():
    return list(map(int, input().strip().split()))
n = int(input())
# conn = sqlite3.connect('./test.sqlite')
conn = sqlite3.connect(':memory:')
cur = conn.cursor()
for i in range(n):
    table_name = input().strip()
    x, y = getints()
    headers = getstrings()
    cur.execute(f"CREATE TABLE {table_name} ({','.join([head + ' TEXT' for head in headers])})")
    conn.commit()
    for j in range(x-1):
        cur.execute(f"INSERT INTO {table_name} VALUES ({','.join(['?' for _ in range(y)])})", getstrings())
        conn.commit()
m = getint()
for i in range(m):
    sql = input().strip()
    first, second = sql.split('=')
    second = f"'{second}'"
    sql = first + '=' + second
    cur.execute(sql)
    for row in cur.fetchall():
        print(' '.join(map(str, row)))

这个代码能够通过题目中的所有样例，但为什么后面的测试点运行异常？
