题目如下
解决思路如下：
找一个本子，把算法思路画下来。可以写的杂乱，后续把思路和流程图画清楚即可。
具体代码实现：
import random
def get_input(): #获取密钥串的长度，获取密钥串中特殊字符的个数，获取密钥串中数字的个数，并返回
pswdlength=input("What's the minimum length")
speclength=input("How many special characters?")
numblength=input("How many numbers?")
return pswdlength,speclength,numblength
def randomspecial():#返回随机特殊字符
lista=('~',"!","@","#","$","%","&","*","(",")","_","+","-","=")
i=random.randint(0,len(lista)-1)
return lista[i]
def randomcharacter():#返回随机字母
listb=("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z")
j=random.randint(0,len(listb)-1)
return listb[j]
def producelist(pswdlength,speclength,numblength): #产生一个列表
list = {}
pswdlength = int(pswdlength)
speclength = int(speclength)
numblength = int(numblength)
leftlength = pswdlength - speclength- numblength
for i in range(0,pswdlength):
if speclength>0:
list[i]=randomspecial()
speclength = speclength - 1
elif numblength>0:
list[i]=random.randint(0,9)
numblength = numblength - 1
elif leftlength>0:
list[i]=randomcharacter()
leftlength = leftlength - 1
#print("字符串长度是{0}".format(len(list))) #debug 用
return list
def randomlizelist(list): #交换算法，遍历key,随机和字典里面其它的key下的value进行交换。
listlength = len(list)
for i in range(0,listlength-1):
j = random.randint(0,listlength-1)
temp = list[i]
list[i] = list[j]
list[j] = temp
return list
if __name__ == '__main__':
pswdlength,speclength,numblength = get_input()
list=producelist(pswdlength,speclength,numblength)
list=randomlizelist(list)
print("Your password is ",end="")
for i in range(0,len(list)):
print(list[i],end="")
#debug 用 print("")#debug 用
#debug 用 print(list)#debug 用
效果图：
