Is it bad to use while true Python?

Is it bad to use while true Python?

It is not a bad practice, it just means that you did not think your code through. The condition is required to tell the loop when to finish looping.

Why is while true bad?

The second will only "do something" when the statement evaluates to true. I think what you are looking for is a do-while loop. I 100% agree that while (true) is not a good idea because it makes it hard to maintain this code and the way you are escaping the loop is very goto esque which is considered bad practice.

How do you break a while true in Python?

Python provides two keywords that terminate a loop iteration prematurely:

1. The Python break statement immediately terminates a loop entirely. Program execution proceeds to the first statement following the loop body.
2. The Python continue statement immediately terminates the current loop iteration.

Should I avoid while true?

I 100% agree that while (true) is not a good idea because it makes it hard to maintain this code and the way you are escaping the loop is very goto esque which is considered bad practice. Try: do { //do something } while (! something);

When would you use while true?

A while-loop executes code repeatedly as long as a given boolean condition evaluates to True . Using while True results in an infinite loop.

How do I get out of while true?

Typically, in Python, an infinite loop is created with while True: Instead of True , you can also use any other expression that always returns true . Another way to terminate an infinite loop is to press CTRL+C . When writing infinite loops, make sure you use the break statement to exit the loop at some point.

Why is my while loop infinite Python?

A loop becomes infinite loop if a condition never becomes FALSE. You must use caution when using while loops because of the possibility that this condition never resolves to a FALSE value. This results in a loop that never ends. Such a loop is called an infinite loop.

Is while true OK?

"while True" in itself is not bad practice/style, but using a "while True" loop in conjunction with a "break" could be considered bad practice because it can almost always be rewritten as a "while something" loop, which improves readability and maintainability.

What does while true is true mean in Python?

• Q: What does “while True” mean in Python? Answer: While True is True means loop forever. The while loop will run as long as the conditional expression evaluates to True. Since True always evaluates to True, the loop will run indefinitely, until something within the loop returns or breaks.

When is the while true condition checked in Python?

• The while loop condition is checked again. If the condition evaluates to True again, the sequence of statements runs again and the process is repeated. When the condition evaluates to False, the loop stops and the program continues beyond the loop.

Which is more Pythonic break or while true?

• The while True format is more pythonic since you know that break is breaking the loop at that exact point, whereas do_next = False could do more stuff before the next evaluation of do_next. while loops continue to loop until the condition is false.
