What is the usage of “while true” in Python?

In Python, `while True` is used to create an infinite loop. An infinite loop is a loop that does not have a clear termination condition, so it will keep executing until it encounters a break statement or the program is manually interrupted.

Here is an example using a while True loop:

while True:
    # 执行一些操作
    # 如果满足某个条件，则使用 break 语句来退出循环
    if condition:
        break

In this example, the loop will continue to execute until a certain condition is met before it exits. You can perform some operations within the loop and use a break statement to stop the loop as needed.

It is important to note that when using infinite loops, ensure there is a condition within the loop that can break it, otherwise the program will continue running indefinitely, causing a deadlock.
