In this example, Python runs a character-by-character comparison as usual. If it runs out of characters, then the shorter string is less than the longer one. This also means that the empty string is the smallest possible string.Comparison of Lists and TuplesIn your Python journey, you can...

Python输出格式化 格式化字符串语法 1.format 1.1 Format String Syntax 格式字符串语法 str.format() 方法和 Formatter 类共享相同的格式字符串语法(尽管在 Formatter 的情况下,子类可以定义自己的格式字符串语法)。 语法与格式化字符
Strings can be indexed (subscripted), with the first character having index 0. There is no separate character type; a character is simply a string of size one:字符串可以被索引（下标），其中第一个字符具有索引0。没有单独的字符类型；字符只是字符串大小的字符串：>>> word = 'Python'>>> word[...
While UTF-8 is supported (in string literals, for instance), Python’s variable names use a more limited character set. For example, you can’t use emojis while naming your variables. That’s a good restriction!Now, say that you need to double-check your implementation and want to see ...
