求1-1000的因子数

运用单线程编写1-1000的因子数

#导入模块
import threading
#创建一个字典 ，存放数字及因子
dict1={}
list_num=0
max_count=0

#创建show方法
def show():
global list_num #全局变量
global max_count #全局变量
for i in range(1,1001):
list1=[]
count=0
print(‘数字’,i,‘的因子数有:’,’:’,end=" “)
for j in range(1,i+1):
if i % j==0:
list1.append(str(i))
print(j,end=” ")
count+=1
print()
if count>max_count:
max_count=count
dict1[i]=list1
print(‘最多的因子个数:’,max_count)
thread1=threading.Thread(target=show,)
thread1.start()
thread1.join()

运用多线程编写1-1000的因子数

#导入模块
import threading
lock=threading.Lock() #创建锁
list_num=[i for i in range (1,1001)]

def ff():
global list_num #全局变量
while 1: #循环
i=0
lock.acquire() #获取锁
if list_num!=[]:
i=list_num[0]
del list_num[0]

        lock.release()			#释放锁
    else:
        lock.release()
        break
    list1=[]
    print(threading.current_thread().getName()+'输出:',i,"的因子数",':',end=" ")
    for j in range(1,i+1):
        if i%j==0:
            list1.append(str(j))
            print(j,end=" ")
    print()

#多线程
for i in range(1,5):
thread1=threading.Thread(target=ff,name=“线程”+str(i))
thread1.start()
