Javascript迄今为止添加了前导零
我已创建此脚本来以dd / mm / yyyy的格式提前10天计算日期: var MyDate = new Date(); var MyDateString = new Date(); MyDate.setDate(MyDate.getDate()+10); MyDateString = MyDate.getDate() + '/' + (MyDate.getMonth()+1) + '/' + MyDate.getFullYear(); 通过将这些规则添加到脚本中,我需要使日期显示在日和月部分上的前导零。我似乎无法正常工作。 if (MyDate.getMonth < 10)getMonth = '0' + getMonth; 和 if (MyDate.getDate <10)get.Date = '0' + getDate; 如果有人可以告诉我将这些内容插入脚本的位置,我将非常感激。

为什么Python 3允许“ 00”作为0的文字,却不允许“ 01”作为1的文字?
为什么Python 3允许“ 00”作为原义的0,却不允许“ 01”作为原义的1?有充分的理由吗?这种矛盾使我感到困惑。(我们正在谈论的是Python 3,它故意打破了向后兼容性以实现诸如一致性之类的目标。) 例如: >>> from datetime import time >>> time(16, 00) datetime.time(16, 0) >>> time(16, 01) File "<stdin>", line 1 time(16, 01) ^ SyntaxError: invalid token >>>

如何删除字符串中的前导和尾随零?蟒蛇
我有几个像这样的字母数字字符串 listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', '000alphanumeric'] 除去尾随零的理想输出为: listOfNum = ['000231512-n','1209123100000-n','alphanumeric', '000alphanumeric'] 前导尾随零的期望输出为: listOfNum = ['231512-n','1209123100000-n00000','alphanumeric0000', 'alphanumeric'] 除去前导零和尾随零的期望输出为: listOfNum = ['231512-n','1209123100000-n', 'alphanumeric', 'alphanumeric'] 目前,我已经按照以下方式进行操作,如果有的话,请提出一种更好的方法: listOfNum = ['000231512-n','1209123100000-n00000','alphanumeric0000', \ '000alphanumeric'] trailingremoved = [] leadingremoved = [] bothremoved = [] # Remove trailing for i in listOfNum: while i[-1] == "0": i = i[:-1] …
