You will need to show the Python source code and the corresponding output. Let us implement a lexical analyzer $($also known as a scanner$),$ which is the first phase of a compiler in Python. You must scan for $($a$)$ keywords in Python $($b$)$ identifiers

$($c$)$operators and $($d$)$ separators. Please translate the C code below to Python.
