python 将"26/05/2023" 转成 "2023-05-26" 格式的时间
时间: 2023-07-08 10:10:17 浏览: 79
可以使用Python的datetime模块来实现这个转换,具体的代码如下:
```python
from datetime import datetime
date_str = "26/05/2023"
date = datetime.strptime(date_str, "%d/%m/%Y").strftime("%Y-%m-%d")
print(date)
```
这里首先使用`strptime()`方法将字符串类型的时间转换成datetime类型的时间,并且指定了输入字符串的格式为"%d/%m/%Y"。然后再使用`strftime()`方法将datetime类型的时间转换成字符串类型的时间,并且指定输出的格式为"%Y-%m-%d"。最后打印输出即可得到转换后的时间字符串"2023-05-26"。

你的数据列表中的时间格式是字符串,我们需要将其转换为datetime格式才能比较大小。可以使用datetime.strptime()函数进行转换。然后,我们可以使用比较运算符(<和>)来筛选出符合条件的时间。
下面是代码示例:
```python
from datetime import datetime
data = ['2023-05-10 20:37:49', '2023-05-10 20:37:50', '2023-05-10 20:37:51', '2023-05-10 20:37:52', '2023-05-10 20:37:53', '2023-05-10 20:37:54', '2023-05-10 20:37:55', '2023-05-10 20:37:56', '2023-05-10 20:37:57', '2023-05-10 20:37:58', '2023-05-10 20:37:59', '2023-05-10 20:38:00', '2023-05-10 20:38:01', '2023-05-10 20:38:02', '2023-05-10 20:38:03', '2023-05-10 20:38:04', '2023-05-10 20:38:05', '2023-05-10 20:38:06', '2023-05-10 20:38:07', '2023-05-10 20:38:08', '2023-05-10 20:38:09', '2023-05-10 20:38:10', '2023-05-10 20:38:11', '2023-05-10 20:38:12', '2023-05-10 20:38:13', '2023-05-10 20:38:14', '2023-05-10 20:38:15', '2023-05-10 20:38:16', '2023-05-10 20:38:17', '2023-05-10 20:38:18', '2023-05-10 20:38:19', '2023-05-10 20:38:20', '2023-05-10 20:38:21', '2023-05-10 20:38:22', '2023-05-10 20:38:23', '2023-05-10 20:38:24', '2023-05-10 20:38:25', '2023-05-10 20:38:26', '2023-05-10 20:38:27', '2023-05-10 20:38:28', '2023-05-10 20:59:25', '2023-05-10 20:59:26', '2023-05-10 20:59:27', '2023-05-10 20:59:28', '2023-05-10 20:59:29', '2023-05-10 20:59:30', '2023-05-10 20:59:31', '2023-05-10 20:59:32', '2023-05-10 20:59:33', '2023-05-10 20:59:34', '2023-05-10 20:59:35', '2023-05-10 20:59:36', '2023-05-10 20:59:37', '2023-05-10 20:59:38', '2023-05-10 20:59:39', '2023-05-10 20:59:40', '2023-05-10 20:59:41', '2023-05-10 20:59:42', '2023-05-10 20:59:43', '2023-05-10 20:59:44', '2023-05-10 20:59:45', '2023-05-10 20:59:46', '2023-05-10 20:59:47', '2023-05-10 20:59:48', '2023-05-10 20:59:49', '2023-05-10 20:59:50', '2023-05-10 20:59:51', '2023-05-10 20:59:52', '2023-05-10 20:59:53', '2023-05-10 20:59:54', '2023-05-10 20:59:55', '2023-05-10 20:59:56', '2023-05-10 20:59:57', '2023-05-10 20:59:58', '2023-05-10 20:59:59', '2023-05-10 21:00:00']
# 将字符串转换为datetime格式
data = [datetime.strptime(d, '%Y-%m-%d %H:%M:%S') for d in data]
# 设置起止时间
start_time = datetime.strptime('2023-05-09 18:04:13', '%Y-%m-%d %H:%M:%S')
end_time = datetime.strptime('2023-05-09 23:47:24', '%Y-%m-%d %H:%M:%S')

输出结果为:
