What is the 'while True' loop?

The 'while True' loop is a type of loop in Python that runs indefinitely until a certain condition is met. It is often used in situations where you want to keep running a piece of code until you explicitly tell it to stop.

The syntax of the 'while True' loop is as follows:


while True:
    # code block

As you can see, the loop condition is simply the boolean value True. This means that the loop will keep running until it is explicitly broken out of.

How does it work?

The 'while True' loop works by continuously checking the condition (which is always True) and running the code block inside the loop. The loop will keep running until it encounters a break statement or until the program is terminated.

Here's an example of how the 'while True' loop can be used:


while True:
    user_input = input("Enter a number: ")
    if user_input == "quit":
        break
    else:
        print("You entered: ", user_input)

In this example, the loop will keep running until the user enters the word "quit". When this happens, the loop is broken out of and the program exits.

Conclusion

The 'while True' loop is a powerful tool that can be used in many different situations. It allows you to keep running a piece of code indefinitely until a certain condition is met. By understanding how it works, you can use it to write more efficient and effective Python code.
