可以使用open()函数以二进制读取模式打开文件,并使用read()方法读取文件内容,得到一个bytes对象。下面是读取二进制文件并转换为bytes对象的示例代码: # 从二进制文件中读取数据并转换为bytes对象withopen('binary_file.bin','rb')asf:data=f.read()print(data) 1. 2. 3. 4. 5. 在上面
在Python中,可以通过bytes()函数来实现。 # 创建一个字节对象,包含字符串“Hello, World!”的字节表示byte_object=bytes("Hello, World!",'utf-8') 1. 2. 这行代码做了以下操作: 使用bytes()函数将字符串转换为字节格式,'utf-8'是字符编码格式。 步骤2:使用print函数输出字节对象 创建完字节对象后,我们可...
Python自制模块分享——进制数 这个模块可以在很多进制中计算和转换,支持平衡三进制。 复制下面的代码,然后新建一个Python文件并粘贴,再保存到Python的安装目录中,文件名为进制数,即可。接下来,只需在Python中写“import 进制数”即可使用。 '''以进制的形式表示数,可以计算和转换,支持平衡三进制。'''平衡三负='T...

Any binary values over 127 must be entered into bytes literals using the appropriate escape sequence.As with string literals, bytes literals may also use a r prefix to disable processing of escape sequences. See String and Bytes literals for more about the various forms of bytes literal, ...
