Solution 1: Use the str() Function to Convert it into a String To resolve this “TypeError”, the “str()” function is utilized to convert the integer into strings. This is because the “re.sub()” method only accepts the string as an argument. The example code shown below will show...
1. Convert Bytes to String Using the decode() Method The most straightforward way to convert bytes to a string is using thedecode()method on the byte object (or the byte string). This method requires specifying the character encoding used. Note: Strings do not have an associated binary enco...
