In Python, the "not equal" operator is used to compare two values and determine whether they are not equal to each other. It is represented by the symbol !=. The result of the comparison is a Boolean value: True if the values are not equal, and False if the values are equal. ...

在我们这个技术驱动的社会中,小工具和硬件只是硬币更明显的一面。在这一章中,我们将讨论编程的基础知识。我们还将看看数字系统的可见部分:硬件。 到底什么是编程? 基本上,编程是告诉数字设备,比如你的个人电脑,做什么的行为。我们键入由编程语言定义的命令列表,以便发生有用或有趣的事件。正确编程的计算机运行着世界...

,双字符运算符包括:<=, >=, ==, != 。若本轮扫描的第一个字符为B型单字符运算符时,先查看下一个字符是否是“=”,如果是,则返回这两个字符代表的token,如果否,则返回这个字符代表的 token 。例如,如果扫描到“>”,则查看下一个字符是否是 “=” ,是则返回 T_GREATEEQUAL,否则返回T_GREATTHAN。
But Python sees two different sequences of code points, and considers them not equal. The solution is to use Unicode normalization, provided by the unicodedata.normalize function. The first argument to that function is one of four strings: 'NFC', 'NFD', 'NFKC', and 'NFKD'. Let’s start...
