可以使用SQL语句来实现对数据库中的语数英字段的总和进行排序,然后使用pymysql库来连接数据库并执行查询。

首先,确保已经安装了pymysql库:

pip install pymysql

然后,使用以下代码连接数据库并执行排序查询:

import pymysql

# 连接数据库
connection = pymysql.connect(host='localhost', user='root', password='password', db='database_name')
cursor = connection.cursor()

# 执行排序查询
sql = "SELECT student_name, chinese_score, math_score, english_score, (chinese_score + math_score + english_score) as total_score FROM students ORDER BY total_score DESC"
cursor.execute(sql)

# 获取查询结果
results = cursor.fetchall()

# 输出查询结果
for row in results:
    student_name = row[0]
    chinese_score = row[1]
    math_score = row[2]
    english_score = row[3]
    total_score = row[4]
    print(f"Student: {student_name}, Chinese Score: {chinese_score}, Math Score: {math_score}, English Score: {english_score}, Total Score: {total_score}")

# 关闭数据库连接
connection.close()

在上面的代码中,需要将hostuserpassworddb替换为实际的数据库连接信息。然后,执行排序查询语句,将结果存储在results变量中,然后逐行输出查询结果。

请根据实际情况修改代码中的数据库连接信息和查询语句
