python - 如何替换字典值中的字符串

Question

我的 parent 字典在下面

d = 
[{"code":1, "description":"This is only one %s", "name":"Hello"},
"code":2, "description":"This %s has one more %s", "name":"World"}]

我的输入 {'code':1, 'details':['A']}预计出 {"description":"This is only one A", "name":"Hello"}我的输入 {'code':2, 'details':['A','B']}预计出 {"description":"This A has one more B", "name":"World"}

有%s在说明中

它必须替换为 details 中的值 key

Answer 1

如果您通过您的 values作为对象元组，您可以使用 %s和字符串格式。

d=[{"code":1, "description":"This is only one %s", "name":"Hello"},
{"code":2, "description":"This %s has one more %s", "name":"World"}]

def replace(code, values):
    for row in d:
        if row.get('code', None) == code:
            return {
                'description': row['description'] % (values),
                'name': row['name'],
            }
    return 'Code not Found'

>>> replace(1, ('A'))
{'description': 'This is only one A', 'name': 'Hello'}
>>> replace(2, ('A', 'B'))
{'description': 'This A has one more B', 'name': 'World'}
>>>
