print(f"The size of '{file_path}' is {size} bytes.") except FileNotFoundError: print("The file does not exist.") 在这个示例中,我们首先导入os模块,然后定义一个文件路径。使用os.path.getsize(file_path)获取文件大小,并处理可能的FileNotFoundError异常。 二、检查文件路径的有效性 在使用getsize...
if hasattr(obj, '__slots__'): # can have __slots__ with __dict__size += sum(get_size(getattr(obj, s), seen) for s in obj.__slots__ if hasattr(obj, s))return size除去判断__dict__和__slots__属性的部分（针对类对象），它主要是对字典类型及可迭代对象（除字符串、bytes、bytear...
File object hastellmethod that can be used to get the current cursor location which will be equivalent to the number of bytes cursor has moved. So this method actually returns the size of the file in bytes. # approach 3# using file object# open filefile =open('d:/file.jpg')# get th...
我们可以使用该函数来计算 bytes 对象的大小。 importsys bytes_data=b'Hello, World!'size=sys.getsizeof(bytes_data)print(f'Size of bytes_data:{size}bytes') 1. 2. 3. 4. 5. 输出结果: Size of bytes_data: 37 bytes 1. 需要注意的是,sys.getsizeof() 函数返回的大小包括对象本身占用的内存以...

File Size in Python The python os module has stat() function where we can pass the file name as argument. This function returns a tuple structure that contains the file information. We can then get its st_size property to get the file size in bytes. Here is a simple program to print ...
ast模块可用于将字节码base64str转换为适当的字节测试环(bytes)对象。 Example: import astx = "b'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9TJHHVk5KOtJ4d154qBhNqf9LGB4svlQkPHue2XNQJUtp8ZLe9dqzk8w=='"out = ast.literal_eval(x) Output: >>> outb'gAAAAABicrsec2Ce4oBYs4pzEpEHou1ZkR4IHai76C9...
四、文件中的内容定位f.read() 读取之后,文件指针到达文件的末尾,如果再来一次f.read()将会发现读取的是空内容,如果想再次读取全部内容,必须将定位指针移动到文件开始: f.seek(0) 这个函数的格式如下(单位是bytes): f.seek(offset, from_what) from_what表示开始读取的位置,offset表示从from_what再移动一定量...
