如何安全地终止python循环？

while True:
    # 循环代码
    if condition:
        break  # 满足条件时终止循环
    # 循环后的代码

def my_function():
    while True:
        # 循环代码
        if condition:
            return result  # 满足条件时终止循环并返回结果
        # 循环后的代码

my_list = [1, 2, 3, 4, 5]
my_iterator = iter(my_list)

while True:
    try:
        item = next(my_iterator)
        # 循环代码
        if condition:
            raise StopIteration  # 满足条件时抛出StopIteration异常终止循环
        # 循环后的代码
    except StopIteration:
        break
