Utility Function in Python

Let’s see what the importance of  Utility Functions in Python is. we will understand it with some easy and effective examples to help us understand the topic more briefly.

Utility Function in Python

A utility function in Python is a small, self-contained piece of code that performs a given specific task. It makes the given task easy to understand and work on it. This particular code is
respectively used across various parts of the code. They take parameters and return values, like other functions. It is an important part of software development and maintenance. some of the utility functions often used in many programs are formatting data, calculating the length of a string… It is also used in manipulation functions and mathematical calculations like strip(), replace() and sum(), max() respectively.

some common characteristics of utility functions:

1. Specific Purpose: They perform a specific task, like formatting a string or data, or calculating any mathematical operation…
2. Reusability: They can be called from multiple places in the code.
3. Encapsulation: They encapsulate a specific piece of functionality, which makes the main code easier to read.Here’s a simple example of a utility function in Python:

   def format_name(first_name, last_name):
       return f"{first_name.strip().title()} {last_name.strip().title()}"
   full_name = format_name(" john ", "DOE")
   print(full_name)  
   full_name = format_name("Ridhi","Ardeshna")
   print(full_name)
   

   In this example, ‘format_name’ is a utility function that ensures the names are properly called. As you see we can call this function whenever and wherever we need to format the name in the code.

   Output: 
   John Doe 
   Ridhi Ardeshna
