While loops are a fundamental programming construct that allows us to automate repetitive tasks, making programs more efficient and effective, a while loop in Python allows you to repeatedly execute a code block if a certain condition is true. In the real world, loops are used in a wide range of applications

Data processing and analysis: Loops can be used to read and process large amounts of data, allowing businesses and organizations to extract insights and make informed decisions.
Scientific research: loops can run simulations, analyze data, and model complex systems, enabling scientists to gain new insights into a wide range of phenomena.
Automation and control systems: Loops can control machines and processes, allowing for precise and accurate control of industrial and manufacturing processes.
Gaming and entertainment: loops are commonly used in game development to create game logic, animation, and AI routines that make games more engaging and challenging.
Education and training: while loops are used in educational software and training programs to simulate real-world scenarios and allow learners to practice and develop their skills.

While loops are an essential programming construct that helps to automate repetitive tasks and make programs more efficient, effective, and powerful, they are used in a wide range of applications in the real world, from scientific research to entertainment. They are a vital tool for anyone who wants to develop their programming skills.

Here is an example using while in Python:

prompt = "Please enter your age: "
print("Enter 'quit' to exit\n")

while True:
    age = input(prompt)
    if age == "quit":
        break
    age = int(age)
    if age < 3:
        print("Your Ticket is free!")
    elif age <= 12 :
        print("Your ticket cost $10")
    else:
        print("your Ticket cost $15")

Copy this code using "Copy" button above and paste it in your Python ide
Run the code, enter the age get the output..

I hope you have found this useful. I have added the dependent library and version information in the following section.

I found this code snippet by searching "Using while loop in python" in kandi. you can try any use case.

In this solution we have used the following versions. Be mindful to change when working with other versions.

This solution is created using Python version 3.7.15

Using this solution we can able to run the file using while loop in python with simple Steps. This process also facilities an easy to use, hassle free method to create a hands-on working version of code which would help us to run the file using while Loop in Python.
