如何在json中打印列值重复的行？

import json

def print_duplicate_rows(json_data, column_name):
    unique_values = set()
    duplicate_rows = []

    for row in json_data:
        value = row.get(column_name)
        if value in unique_values:
            duplicate_rows.append(row)
        else:
            unique_values.add(value)

    for row in duplicate_rows:
        print(row)

# 示例json数据
json_data = [
    {"id": 1, "name": "John", "age": 25},
    {"id": 2, "name": "Jane", "age": 30},
    {"id": 3, "name": "John", "age": 35},
    {"id": 4, "name": "Mike", "age": 40},
    {"id": 5, "name": "Jane", "age": 45}
]

# 指定列名为"name"
column_name = "name"

# 调用函数打印重复行
print_duplicate_rows(json_data, column_name)
