Python多种方法求某个范围内的所有素数
#方法1
def primeNUM(min,max):
if min==1:
print('')
min += 1
for i in range(min, max+1):
for j in range(2, i + 1):
if i % j == 0: #判断i能不能被整除
break #退出for循环
if j == i: #若j等于i,说明i是素数
print(i,end=" ")
print('')
primeNUM(1,200)
#方法2
def test(num):
list = [] #定义一个列表 用于存储计算的数
i = num -1 # 去除本身
while i > 1: # 去除1
if num %i == 0 : #判断是否有余数
list.append(i) # 将所有的能整除i的数加入列表
i -= 1
if len(list) == 0 and num != 1: # 如果列表为空 就是表示除了1和它本身能整除
print(num,end=' ')
def primeNUM2(min,max):
j = min
while j < max:
test(j)
j += 1
print('')
primeNUM2(1,100)
