客户系统升级，要求用户密码符合一定的规则，即：包含大小写字母、数字、符号，长度不小于8,于是先用python写了个简单的测试程序：

#encoding=utf-8#-------------------------------------------------------------------------------# Name:        模块1# Purpose:## Author:      Administrator## Created:     10-06-2014# Copyright:   (c) Administrator 2014# Licence:     <your licence>#-------------------------------------------------------------------------------import redef checklen(pwd):    return len(pwd)>=8def checkContainUpper(pwd):    pattern = re.compile('[A-Z]+')    match = pattern.findall(pwd)    if match:        return True    else:        return Falsedef checkContainNum(pwd):    pattern = re.compile('[0-9]+')    match = pattern.findall(pwd)    if match:        return True    else:        return Falsedef checkContainLower(pwd):    pattern = re.compile('[a-z]+')    match = pattern.findall(pwd)    if match:        return True    else:       return Falsedef checkSymbol(pwd):    pattern = re.compile('([^a-z0-9A-Z])+')    match = pattern.findall(pwd)    if match:        return True    else:        return Falsedef checkPassWord(pwd):    #判断密码长度是否合法    lenOK=checklen(pwd)    #判断是否包含大写字母    upperOK=checkContainUpper(pwd)    #判断是否包含小写字母    lowerOK=checkContainLower(pwd)    #判断是否包含数字    numOK=checkContainNum(pwd)    #判断是否包含符号    symbolOK=checkSymbol(pwd)    PRint(lenOK)    print(upperOK)    print(lowerOK)    print(numOK)    print(symbolOK)    return (lenOK and upperOK and lowerOK and numOK and symbolOK)def main():    if checkPassword('Helloworld#123'):        print('检测通过')    else:        print('检测未通过')if __name__ == '__main__':    main()
