3.3 Python Array Slicing of String Examples In this section, let’s use the different combinations of three paraments of slice and see how they behave. 3.3.1 Return the entire string without slicing This example doesn’t specify any indexes hence, it returns the entire string as-is without ...
Example 1: Python JSON to dict You can parse a JSON string usingjson.loads()method. The method returns a dictionary. importjson person ='{"name": "Bob", "languages": ["English", "French"]}'person_dict = json.loads(person)# Output: {'name': 'Bob', 'languages': ['English', 'Fr...
args = parser.parse_args() file_path = args.FILE_PATH 时间戳是收集的最常见的文件元数据属性之一。我们可以使用os.stat()方法访问创建、修改和访问时间戳。时间戳以表示自 1970-01-01 以来的秒数的浮点数返回。使用datetime.fromtimestamp()方法,我们将这个值转换为可读格式。
