Take data every second

[AxekA13]

How can I take the data every second? For example, now we have

[{'datetime': '2023-06-25;16:35:00', 'open': 0.2957, 'high': 0.2957, 'low': 0.2955, 'close': 0.2955, 'volume': 45111.8}] [{'datetime': '2023-06-25;16:36:00', 'open': 0.2957, 'high': 0.2957, 'low': 0.2954, 'close': 0.2954, 'volume': 46156.4}]

But how can I take this one? [{'datetime': '2023-06-25;16:35:01', 'open': 0.2957, 'high': 0.2957, 'low': 0.2954, 'close': 0.2954, 'volume': 46156.4}] [{'datetime': '2023-06-25;16:35:02', 'open': 0.2957, 'high': 0.2957, 'low': 0.2954, 'close': 0.2954, 'volume': 46156.4}]
