my_list[min_index] = temp print(my_list)It works by comparing the characters of each string directly from their ASCII values in Python 2 or their Unicode values in Python 3. Don’t believe me? Try it out yourself:"hello" > "the" # returns false "the" > "hello" # returns trueThe...
By default, thejson.dumps()function in Python escapes non-ASCII characters using Unicode escape sequences (e.g.,\uXXXX). If you want to ensure that the output contains only ASCII characters without Unicode escape sequences, you can use theensure_asciiparameter and set it toTrue. Conclusion ...
对齐方式(有返回值) __center() 居中对齐 __ljust() 左对齐 __rjust() 右对齐 对齐函数使用方法都一样则用ljust举例 1 ljust(self, width, fillchar=' ', /)(自(可省略),宽度,填充字符=‘’,/) Return a left-justified string of length width. 返回长度宽度为左对齐的字符串。 Padding is done ...

由于Unicode收录字符已经超过13万个,每个字符至少需要4个字节来保存。这意味着巨大的内存开销,显然是不可接受的。英文字符用ASCII表示仅需1个字节,而用Unicode表示内存开销却增加4倍! Python作者们肯定不允许这样的事情发生,不信我们先来观察下(getsizeof获取对象内存大小): ...
