Compile(): Consider a situation where we have a piece of Python code in a string and we want to compile it so that we can later run it when needed. The compile method does this task. It takes sourcecode as input and returns a code object which is ready to be executed.
compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1)
Source – It can be a normal string, a byte string, or an AST object
Filename -This is the file from which the code was read. If it wasn’t read from a file, you can give a name yourself.
Mode – Mode can be exec, eval or single.
a. eval – If the sorce is a single expression.
b. exec – It can take a block of a code that has Python statements, class and functions and so on.
c. single – It is used if consists of a single interactive statement
Flags (optional) and dont_inherit (optional) – Default value=0. It takes care that which future statements affect the compilation of the source.
Optimize (optional) – It tells optimization level of compiler. Default value -1.

- If the Python code is in string form or is an AST object, and you want to change it to a code object, then you can use compile() method.
- The code object returned by the compile() method can later be called using methods like: exec() and eval() which will execute dynamically generated Python code.
