#方法一:直接复制bytes类型 b'<str>'b = b'Hello World'print(type(b))print(b) #方法二:转换s ='Hello World'b= bytes(s,encoding='utf-8')print(type(b))print(b)#---bytes to string---s = str(b,encoding='utf-8')print(type(s))print(s)#---执行结果---<class'bytes'>b'Hello ...
# Convert the string to a bytes object bytes_object = bytes(string, 'utf-8') # Print the bytes object print(bytes_object) # Convert the bytes object back to a string decoded_string = bytes_object.decode('utf-8') # Print the decoded string print(decoded_string) 输出: b'Hello, world!
class bytes([source[, encoding[, errors]]]) 返回一个新的“bytes”对象, 是一个不可变序列,包含范围为 0 <= x < 256 的整数。 bytes 是 bytearray 的不可变版本 - 它有其中不改变序列的方法和相同的索引、切片操作。 因此,构造函数的实参和 bytearray() 相同。 创建by...
python bytes to string python bytes 转化成 string 会遇到如下错误: codec can't decode byte 0xff in position 5: illegal multibyte sequence 其实还是编码格式的问题,通过使用: ok_cookies = ok_str.decode('iso-8859-1') 1 2 3 4 5 6 7 ok_str=b'\x00\x01\x00\x00\x00\xff\xff\xff\xff\...
string="Hello, World!"encoding="utf-8"# 假设字符串使用UTF-8编码bytes=string.encode(encoding)print("转换后的字节为:",bytes) 1. 2. 3. 4. 步骤三:完成转换并进行其他操作 完成转换后,你可以根据需要对字节进行其他操作,比如写入文件、发送到网络等。
value = bytes_or_str.decode('utf-8') else: value = bytes_or_str return value # Instance of str print(repr(to_str(b'foo'))) print(repr(to_str('bar'))) >>> 'foo' 'bar' 第二个辅助函数也接受bytes或str实例,但它返回的是bytes: ...
详解python string类型 bytes类型 bytearray类型 一、python3对文本和二进制数据做了区分。文本是Unicode编码,str类型,用于显示。二进制类型是bytes类型,用于存储和传输。bytes是byte的序列,而str是unicode的序列。 str类型: >>> s = u'你好' >>> s '你好' >>> type(s)bytes类型: >>> b = b'abc' >>...
Program : Type Hint, String, Bytes, Hex, Base64 In this program, you are required to learn basic concepts ofPython3. Type hints is a feature to specify the type of a variable, which is useful for write correct codes. In all lab assignments, you arerequiredto write Python 3 code with...
open("lol", "w", "utf-8") file.write(u'\ufeff') file.close() (That seems to give the right answer - a file with bytes EF BB BF.) EDIT: S. Lott's suggestion of using "utf-8-sig" as the encoding is a better one than explicitly writing the BOM yourself, but I'll leave...
