convert_to_ascii函数将二进制字符串转换为ASCII。首先将二进制字符串转换为整数,然后使用to_bytes()函数将整数转换为字节串,最后使用decode()函数将字节串解码为ASCII字符串。 主程序部分首先定义了输入的文本input_text,然后调用convert_to_binary函数将文本转换为二进制,并打印出结果。接下来调用convert_to_ascii函数...
(string memory _name) public{ // convert string to bytes first // then convert to bytes8 bytes8 newName=bytes8(bytes(_name)); Names.push(newName); }} 或者你也可以把过去作为论据 function setName(bytes8 _name) public{ Names.push(_name); } 在前端调用时,将字符串转换为字节8,然后将其...

• ASCII: an encoding which handles 128 English characters • Ascii:一种处理128个英语字符的编码方式 • UTF-8: a popular encoding used for Unicode strings which is backwards compatible with ASCII for the first 128 characters. It uses one to four bytes for each character. ...
# 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!' Hello, world! 在这个例子中,我们首先定义一个字符串变量。然后,我们使用构造函数将字符串转换为字节对象,将字符串和编码 () 作为参...

Converting Bytes to Strings: The .decode() Method A bytes object in Python is human-readable only when it contains readable ASCII characters. In most applications, these characters are not sufficient. We can convert a bytes object into a string using the .decode() method: data = bytes([68...
