Changing the Behavior of the type() Function in Python

Python's built-in type() function is extremely useful for determining the data type of an object. However, there may be instances where you want to change the default output to a more concise representation - specifically, to return just the name of the type as a string instead of including additional information. Let’s explore how you can achieve this.

Understanding the Default Behavior of type()

Let’s start by taking a look at how the type() function works out of the box. For instance, if you have a simple string:

The output you get from this code looks like this:

This default output includes the class name, surrounded by angle brackets and a prefix <class special characters, which might not be necessary for all use cases.

The Desired Output

You might prefer a simpler output that only shows the type name. The desired output for the same string could be:

This can enhance readability and improve the presentation of your output, especially when you are displaying data types in a user interface or logging.

The Solution: Using the _name_ Property

To get just the type name as a string, you can use the _name_ property of the type. Below is the updated approach to extract the plain type name:

Step-by-Step Implementation

Declare Your Variable:
First, define your variable as you would normally.

Get the Type Name:
Use the type and _name_ attribute to get the desired output.

This will produce the output:

Why Use __name__?

Simplicity:
It provides a clean, straightforward way to get the name of the type without any extraneous characters.

Clarity:
The resulting string is easier to read, particularly for presentations or logging purposes.

Conclusion

Changing the output of the built-in type() function in Python is a straightforward task. By using the _name_ property, you can easily obtain just the name of the type. This minor adjustment can enhance the overall clarity and usability of your code, particularly in cases where you need a more streamlined display of data types.

Now, go ahead and implement this method in your Python projects to style your type outputs just the way you want them!
