我正在做一個大學項目，從打印兩個給定輸入之間的所有質數開始。后來有人告訴我，它必須與我的課程，網絡管理有關，所以我想在我的腳本末尾添加一個密碼生成器(用于網絡安全)

我把所有的代碼都寫出來了，但是我有一個問題，就是它不能在我打印出來的列表中使用一個隨機素數。它只使用最后一個打印出來的數字，我明白為什么，但是不管怎樣，我能使它使用一個隨機素數，還是我必須把這些數字存儲在某個地方？在#A program to count the prime numbers from a given start to a given end

#importing math function

import math

import os, random, string

#Input the number to start counting from

Starting_number = input("Enter the starting number: ")

#Input the number to end the count on.

Ending_number = input("Enter the number you want to count up to: ")

#if Starting_number is less than 0 it will print out a suitable message.

if Starting_number < 0:

print 'Invalid entry, please enter a positiv number. \nWill count from ',Starting_number, 'to 0 and begin prime number count to',Ending_number, '.'

#If Ending_number is less than or equals to 0 then it will print out a suitable message.

if Ending_number <= 0:

print 'Invalid entry on last input \nPlease enter two positive numbers for the count to work.'

#Starting loop as long as the current count is between Starting_number and Ending_number

for num in range(Starting_number, Ending_number):

#

if all(num%i !=0 for i in range(2,num)):

print num

if num >= 1 and num <= 100:

length = 4

chars = string.ascii_letters + string.digits + '!@#$%^&*()'

random.seed = (os.urandom(1024))

print ''.join(random.choice(chars) for i in range(length))

if num >= 101 and num <= 200:

length = (Ending_number / Starting_number) * 5 + 11

if length >= num:

length = num / 100

chars = string.ascii_letters + string.digits + '!@#$%^&*()'

random.seed = (os.urandom(1024))

print ''.join(random.choice(chars) for i in range(length))
