python之---递归字典None值转‘‘

python的字典将里面的None递归转换成''示例代码

def replace_none_recursive(data):
    if isinstance(data, dict):
        return {k: replace_none_recursive(v) for k, v in data.items()}
    elif isinstance(data, list):
        return [replace_none_recursive(item) for item in data]
    elif data is None:
        return ''
    else:
        return data

nested_dict = {'user': {'name': None, 'info': {'age': 25, 'email': None}}}
result = replace_none_recursive(nested_dict)
