In Python, it's common to have objects within objects. To access objects within objects, you can use the dot notation. Let's take a look at an example. Example 1 class Person: def __init__(self, name, age): self.name ... Read More

An object is said to be hashable if it has a hash value that remains the same during its lifetime. It has a __hash__() method and it can be compared to other objects. For this, it needs the __eq__() or __cmp__()method. If hashable objects are equal when compared, then they ... Read More

Using the inspect module, you can retrieve the source code of a Python function, method, class, or module. The following example demonstrates how to retrieve a function's source code: Example import inspect def my_function(x, y): return x + y source_code = inspect.getsource(my_function) print(source_code) ...

In Python, the built-in class attribute __bases__ is used to get the tuple of base classes of a class. When you define a new class in Python, you can specify one or more base classes from which the new class will inherit. The base classes are specified in parentheses after ... Read More

In Python, base overloading methods are the methods that we can override in the derived class to change the behavior of the object. The base overloading methods are pre-defined special methods in Python that can be used to define how operators and built-in functions should work on user-defined classes. By ... Read More

The __module__ attribute is a built-in class attribute in Python that is used to get the name of the module in which a class is defined. This attribute is useful when you want to check the name of the module in which a particular class is defined. Here are some ... Read More

To extract the number and names of the arguments from a function or function[something] to return ("arg1", "arg2"), we use the inspect module. The given code is written as follows using inspect module to find the parameters inside the functions `aMethod` and `foo`. Example import inspect ... Read More

Recursion is a programming technique, in which a function calls itself one or more times in its body. Usually, it is returning the return value of this function call. If a function definition follows recursion, we call this function a recursive function. A recursive function has to be terminated ... Read More

In Python, you can define a method in such a way that there are multiple ways to call it. Depending on the function definition, it can be called with zero, one, two or more parameters. This is known as method overloading. . In the given code, there is a ... Read More

We can define a python function and execute it at runtime by importing the types module and using its function types.FunctionType() as follows This code works at the python prompt as shown. First we import the types module. Then we run the command dynf=…; then we call ... Read More
