所谓拳不离手，曲不离口

0.000 HBD所谓拳不离手，曲不离口
最近一直忙一些乱七八糟的事情，很久没有写代码了。昨天帮朋友实现一个小功能，用Python实现，发现自己一些最基本的操作都不会了。  (图源 ：[pixabay](https://pixabay.com/)) 比如说Python如何循环操作一个列表中的内容，是用`foreach` 还是`for` 循环，又比如Python中的时间日期怎么操作，比如说如何计算两个时间的差值等等。 好不容易查手册搞定了这些问题，但是在写一段计数代码，程序又出错了，`cnt++`为啥就不对呢？研究了好一阵才发现这种写法是不支持的，改成`cnt+=1`就好啦。 至于涉及到STEEM相关的内容，我又是一通查STEEM的开发资料，以及参考我以前的各种代码，总算不辜负朋友的期望，总算实现了这个小功能。 尽管最终达成了目标，但是对这效率我是不太满意的，其实一点难点都没有，主要时间就浪费在查手册看一些基本的语法和操作了。 由此可见，`拳不离手，曲不离口`又多么重要，才一段时间不接触，就忘掉了怎么弄，以往这些语法什么的东西尽管不能说是滚瓜烂熟，但是至少拿起来就能写啊。  (图源 ：[pixabay](https://pixabay.com/)) 当然，其实还有一大部分因素是自己年纪大了，记忆力不佳。所以年轻人们啊，努力要趁早啊，到我这年纪，吃喝玩乐还行，不服老不行呀。 ---- <center><strong>Vote For Me As Witness</strong> https://steemit.com/~witnesses type in **`oflyhigh`** and click ***`VOTE`*** [](https://steemit.com/~witnesses) [Vote @oflyhigh via Steemconnect](https://steemconnect.com/sign/account-witness-vote?witness=oflyhigh&approve=1) <strong>Thank you!</strong></center>
