A Docstring in Python is a string used for adding comments or summarizing a piece of code in Python.

The main difference between Javadoc and Docstring is that docstring is available during runtime as well.

Whereas, Javadoc is removed from the Bytecode and it is not present in .class file.

We can even use Docstring comments at run time as an interactive help manual.

In Python, we have to specify docstring as the first statement of a code object, just after the def or class statement.

The docstring for a code object can be accessed from the ‘doc‘ attribute of that object.
