师从‘百测’besttest 今日牛老师布置了一个作业,生成一个随机密码,且要包含大写字母.小写字母.数字和特殊字符,且不能重复. 想着先生成密码,然后用各字符去检查是否存在,使用for嵌套循环. import string l = [','123!@#qweA'] i = 0 n = 3 while i < n: # 从a-zA-Z0-9特殊字符中生成指定数量的随机字符 #pwd = ''.join(random.sample(string.ascii_letters + string.dig
方法一: public static int indexOf (字符串/字符,int从第几位开始,int共查几位) string tests = "1absjjkcbfka2rsbcfak2bfka1"; //测试字符串 int i = tests.IndexOf("2b",5,tests.Length-5); //查找从第五字符向后查找“2b” textBox2.Text = i.ToString(); int i = tests.IndexO
//超过长度的字符截取指定长度,超出部分以...显示 function subString(str, len) { var newLength = 0; var newStr = ""; var chineseRegex = /[^\x00-\xff]/g; var singleChar = ""; var strLength = str.replace(chineseRegex, "**").length; if (strLength >
格式化字符串长度 方法 function formatWidth(str, width){ str += '' if(str.length<width) '+str, width) else return str } 测试代码 a = console.log(a,formatWidth(a,)) a = console.log(a,formatWidth(a,)) a = console.log(a,formatWidth(a,)) 运行结果 获取格式化时间字符串 方法 function tim
