递归迭代嵌套的dict with list，并替换匹配的值

def replace_value(data, target_value, replacement):
    if isinstance(data, dict):
        for key, value in data.items():
            if value == target_value:
                data[key] = replacement
            else:
                replace_value(value, target_value, replacement)
    elif isinstance(data, list):
        for i in range(len(data)):
            if data[i] == target_value:
                data[i] = replacement
            else:
                replace_value(data[i], target_value, replacement)

# 示例数据
data = {
    'key1': 'value1',
    'key2': [
        {'key3': 'value2'},
        {'key4': 'value3'}
    ]
}

# 替换值为'value2'的元素为'replacement'
replace_value(data, 'value2', 'replacement')

print(data)

{
    'key1': 'value1',
    'key2': [
        {'key3': 'replacement'},
        {'key4': 'value3'}
    ]
}
