Question

我是Python的新手，我正在尝试创建一个通过PyMySQL将数据保存到数据库的表单，但是我在连接数据库时遇到了问题。我已经按照示例代码（我的版本在下面）并彻底检查了所有语法和语音标记，但仍然出现以下错误。

File "c:\Users\Nimrod\Nimrod Dropbox\Dropbox\Nimrodsky\Python\Adiabatic Equation\DB connect with PyMySQL.py", line 10, in <module> charset='utf8')
File "C:\ProgramData\Anaconda3\lib\site-packages\pymysql\__init__.py", line 90, in Connect return Connection(*args, **kwargs)
File "C:\ProgramData\Anaconda3\lib\site-packages\pymysql\connections.py", line 706, in __init__ self.connect()
File "C:\ProgramData\Anaconda3\lib\site-packages\pymysql\connections.py", line 922, in connect self.host_info = "socket %s:%d" % (self.host, self.port)
TypeError: %d format: a number is required, not str

import pymysql
import pymysql.cursors

# Connect to the database
connection = pymysql.connect(host='sql8.freesqldatabase.com', 
                            port='3306', 
                            user='********', 
                            password='**********', 
                            db='*********',
                            charset='utf8')


try:
    with connection.cursor() as cursor:
        # Create a new record
        sql = "INSERT INTO `client` (`ID`, `client_name`, `client_address_1`, `client_address_2`, `client_address_3`, `client_postcode`, `occupier_name`, `install_address_1`, `install_address_2`, `install_address_3`, `install_postcode`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s)"
        cursor.execute(sql, ('1', 'Terry Jones', '10 DOwning Street', 'Guildford','Surrey', 'GU1 5HA', 'Paul Smith', 'Wimbledon Hill', 'Wimbledon', 'London', 'SW19 5QT'))

    #connection is not autocommit by default. So you must commit to save
    #your changes.
    connection.commit()

    with connection.cursor() as cursor:
        # Read a single record
        sql = "SELECT `id`, `occupier_name` FROM `client` WHERE `client_name`=%s"
        cursor.execute(sql, ('Terry Jones',))
        result = cursor.fetchone()
        print (result)

finally:
    connection.close

Answer 1

端口必须是整数：port=3306。

％s设置正确，但PyMySQL仍抱怨％d
