Question

我在SQLite中使用sqlite3和DB浏览器。我的代码：

def createuser(user,password,dbname):
    sql_insert = "INSERT INTO login VALUES 
('{user}','{password}')".format(user=user, password=password)
    print sql_insert
    conn = sqlite3.connect(dbname)
    c = conn.cursor()
    c.execute(sql_insert)
    # Save (commit) the changes
    conn.commit()

但是我收到数据库被锁定的错误。我不知道该怎么办，因为它昨天正在工作。当我在数据库浏览器中执行SQL代码以显示表“登录”中的值时，这些值就是这些值所在的位置，有时我会在此程序中输入值，有时它们不会出现。吨。这有点来自下面发布的较长代码，但错误消息仅涉及此功能。

import sqlite3
DEBUG = True
# sets up database


def setup():
    conn = sqlite3.connect('Practice.db')
    c = conn.cursor()
    c.execute('''CREATE TABLE login
     (Username text, Password text )''')
    conn.commit()


# main function
def main(dbname, user, password, hummus):
    conn = sqlite3.connect('Practice.db')
    c = conn.cursor()
    if hummus == "newuser":
        print "Creating user {user}".format(user=user)
        createuser(user, password, dbname)
    else:
        print "Not running"
        pass


    # Create table
    # c.execute('''CREATE TABLE login
      #   (Username text, Password text )''')

    # Insert a row of data
    # c.execute("INSERT INTO username VALUES 
    # ('raw_input()','BUY','RHAT',100,35.14)")

# creates new user in table 'username'


# creates new user in table 'username'
def createuser(user,password,dbname):
    sql_insert = "INSERT INTO login VALUES 
('{user}','{password}')".format(user=user, password=password)
    print sql_insert
    conn = sqlite3.connect(dbname)
    c = conn.cursor()
    c.execute(sql_insert)
    # Save (commit) the changes
    conn.commit()

    # We can also close the connection if we are done with it.
    # Just be sure any changes have been committed or they will be 
lost.
    conn.close()


if __name__ == '__main__':
    #setup()
    #exit()
    if DEBUG:
        db = 'Practice.db'
        user = 'tim'
        password = 'massimo'
        pass_check = True
        main(db, user, password, 'newuser')

    else:
        db = 'Practice.db'
        user = raw_input('Enter username ')
        password = raw_input('Enter password ')
        pass_check = raw_input('verify password ')
        if not password == pass_check:
            print ('Passwords do not match. ')

        main(db, user, password, 'newuser')
        #conn = sqlite3.connect(dbname)
        #conn.commit()
        #elif perform == ("login",'Login'):







        #main(db, user, password, action)

编辑

因为我是从本地主机运行的，所以问题是我在尝试添加数据库的同时打开了数据库。 SQLite的DB Browser阻止了这一点。

SQL数据库被锁定了吗？
