such as UTF-8. While bytes represent raw binary data. A byte object is immutable and consists of an array of bytes (8-bit values). In Python 3, string literals are Unicode by default, while byte literals are prefixed with ab.
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...

You can use the built-ineval()to evaluate arbitrary Python expressions from string-based or compiled-code-based input. This is a good option if you need to dynamically evaluate Python expressions. When you pass a string argument toeval(), it compiles it into bytecode and evaluates it as a...
