Python Code Introspection for Software Development

Code introspection is the ability to examine and analyze code at runtime. In Python, this is made possible through several built-in functions and modules. By leveraging introspection, developers can improve their code's readability and maintainability, as well as diagnose issues and optimize performance.

dir()

The dir() function returns a list of attributes and methods of an object. It is a useful function for exploring the attributes and methods of an object, especially if you are working with a new module or library. For example, to see all the attributes and methods of a module, you can call dir() on it:

import pandas as pd
print(dir(pd))

This will print a list of all the attributes and methods of the pandas module.

type()

The type() function returns the type of an object. It is useful for determining the type of an unknown object or variable. For example, to determine the type of a variable, you can call type() on it:

x = 42
print(type(x))

This will print int.
