Mysql连接器在使用python连接器时出现语法错误

因此，我用python制作了一个密码管理器，使用mysql存储数据。当我尝试使用mysql连接器创建表时，出现以下错误：

您的SQL语法有错误；请查看与MySQL服务器版本对应的手册，以获取第1行“”附近要使用的正确语法

我的完整代码是

import mysql.connector as mysql
import tkinter as tk

from simplecrypt import *

def createusr():
    global oo
    global pss
    top1 = tk.Toplevel(root)
    top1.title('Create new user ')

login.place(relx = 0.2, rely = 0.7, relheight = 0.05, relwidth = 0.48)

root.mainloop()

问题在于：

    def newacc():
        check = str("DROP TABLE IF EXISTS" + str(oo.get()))
        table = "CREATE TABLE {0}(SERVICE VARCHAR(100), USERNAME VARCHAR(100),PASSWORD VARCHAR(256))".format(str(oo.get()))
        cursor.execute(table)
        msql.close()

'''

你能帮忙吗？

check=str（“如果存在，请删除表”+str（oo.get（））

在EXISTS关键字后面需要一个空格。

我猜是哪里出了问题

def newacc():
    check = "DROP TABLE IF EXISTS {}".format(oo.get()) 
    table = '''CREATE TABLE `{}`(
        `SERVICE` VARCHAR(100), 
        `USERNAME` VARCHAR(100),
        `PASSWORD` VARCHAR(256))'''.format(oo.get())
    cursor.execute(table)
    msql.close()

请尝试一下，如果有任何错误，请告诉我

干杯

虽然我没有执行变量检查，但我正在执行表。这是什么错误？您确实缺少一个空格：

{0}（服务

应该是

{0}（服务

。如果这还不能解决问题，你应该在格式化后打印出

表

变量，并仔细检查它。@克里斯，实际上我不认为问题出在空格上。我确实注意到当它被指出时，但程序即使在解决空格后也无法工作。@CoolCloud，你能告诉我问题出在哪里吗你？@avisharma试着用反勾号（`）来表示密码，语法实际上是错误的，试着用多行代码在这里生成一个表，

{0}

意味着什么？你实际上在

check

变量中连接了两个字符串。并且试着把它变成

{}

{0}

是有效的python：它引用了

格式中的参数顺序。在这种情况下，它与
{}
相同，因为
格式
@chris oh只有一个参数，我明白了，那么他可能应该尝试使用多行字符串并尝试使用反勾（`）指定列名和表名，因为我相信
密码
是一个MySQL函数。@Cloud--ya，你说的空间不是一个问题是对的。对密码使用反勾号似乎是有可能的！如果不是这样，它必须是
oo.get（）
返回的任何内容。
