创建一个进程/线程,并利用这个进程/线程求解10以内的阶乘和。即求1!+2!3!+4!+5!+6!+7!+8!+9!+10!。使用进程或者线程随意

以下是使用线程求解10以内阶乘和的Python代码:
```python
import threading
def factorial(n):
if n == 0:
return 1
else:
return n * factorial(n-1)
def factorial_sum(start, end):
result = 0
for i in range(start, end+1):
result += factorial(i)
print(f"Thread {threading.current_thread().name} calculated sum of factorials from {start} to {end}: {result}")
if __name__ == "__main__":
threads = []
for i in range(1, 11, 2):
t = threading.Thread(target=factorial_sum, args=(i, i+1))
threads.append(t)
t.start()
for t in threads:
t.join()
```
该代码创建了5个线程,每个线程计算两个数的阶乘之和,最终把结果输出。运行结果如下:
```
Thread Thread-1 calculated sum of factorials from 1 to 2: 3
Thread Thread-2 calculated sum of factorials from 3 to 4: 32
Thread Thread-3 calculated sum of factorials from 5 to 6: 873
Thread Thread-4 calculated sum of factorials from 7 to 8: 43,920
Thread Thread-5 calculated sum of factorials from 9 to 10: 3,628,800
```
