假定某系统密码设定规则如下:
(1). [a-z]之间至少有1个字母 【判断条件提示:j >= 'a' and j <= 'z',以下类似】
(2). [A-Z]之间至少有1个字母
(3). [0-9]之间至少有1个数字
(4). [@#$%&]中至少有2个字符
(5).密码的最短长度:7
(6).密码的最大长度:13
(7).密码不能包含空格
请编程实现下述问题:程序接受键盘输入的多个逗号分隔的密码,并根据上述密码设定规则对所有密码进行检测,将符合条件的密码以字符串形式打印,每个密码用逗号分隔。
例:
如果以下密码作为程序的输入:ABd1#234@1,a F1#@12,2w&a3E,2We3345,dHuD&u12=e, ABd1234@1,则程序的输出应该是:符合密码设定标准的结果为:ABd1#234@1,2w&a3E
代码如下,望采纳,谢谢!
def check_password(password):
# fill your codes after this line
s=[0,0,0,0]
for c in password:
if c >= '0' and c <= '9':
s[0]=1
if c >= 'A' and c <= 'Z':
s[1]=1
if c >= 'a' and c <= 'z':
s[2]=1
if c in '@#$%&':
s[3]+=1
if c == ' ':
return False
if sum(s) >= 5 and s[3] >= 2 and len(password) >= 7 and len(password) <= 13:
return True
else:
return False
# end of your codes
# do not modify
if __name__ == "__main__":
passwords = input().split(',')
oks=[]
for password in passwords:
if check_password(password):
oks.append(password)
print("符号密码设定标准的结果为:",','.join(oks))
提供参考代码:
import re
print('请输入密码:')
password=input().split(',')
value=[]
for p in password:
if len(p)<6 or len(p)>12:
continue
if not re.search('[a-z]',p):
continue
elif not re.search('[0-9]',p):
continue
elif not re.search('[A-Z]',p):
continue
elif not re.search('[@#$]',p):
continue
else:
pass
value.append(p)
print(','.join(value))
经过整理调试,得到了相应的代码,过程不易,希望能够对你有帮助!
