对动态列中的数据组进行计数

import mysql.connector

# 连接到MySQL数据库
cnx = mysql.connector.connect(user='username', password='password',
                              host='localhost', database='database_name')

# 创建游标对象
cursor = cnx.cursor()

# 执行查询语句
query = "SELECT dynamic_column FROM table_name"
cursor.execute(query)

# 统计数据组的数量
group_counts = {}
for row in cursor:
    dynamic_column = row[0]
    group_count = len(dynamic_column)
    if group_count in group_counts:
        group_counts[group_count] += 1
    else:
        group_counts[group_count] = 1

# 打印统计结果
for group_count, count in group_counts.items():
    print("数据组数量为{}的数量为{}".format(group_count, count))

# 关闭游标和数据库连接
cursor.close()
cnx.close()
