取消所有异步任务/不一致的py循环

import asyncio

async def my_coroutine():
    await asyncio.sleep(10)
    print("Coroutine finished")

async def main():
    tasks = [asyncio.create_task(my_coroutine()) for _ in range(5)]
    
    # 假设在某个时刻你需要取消所有任务
    for task in tasks:
        task.cancel()
    
    try:
        await asyncio.gather(*tasks)
    except asyncio.CancelledError:
        print("All tasks were cancelled")

asyncio.run(main())

# 不一致的循环示例
for i in range(5):
    print(i)

while True:
    print("Infinite loop")

# 改进后的代码
def print_numbers():
    for i in range(5):
        print(i)

def infinite_loop():
    while True:
        print("Infinite loop")

print_numbers()
# infinite_loop()  # 注意：这个函数会导致无限循环，慎用

try:
    await asyncio.gather(*tasks, return_exceptions=True)
except asyncio.CancelledError:
    print("Some tasks were cancelled")
