如何在python中停止for循环的迭代？(滑动窗口问题)

# 示例：滑动窗口问题
def find_target(nums, target):
    for i in range(len(nums) - 1):
        for j in range(i + 1, len(nums)):
            if nums[i] + nums[j] == target:
                print(f"Found target at indices {i} and {j}")
                break  # 终止内层循环
        else:
            continue
        break  # 终止外层循环

nums = [2, 7, 11, 15]
target = 9
find_target(nums, target)
