在了解字符串如何创建有一个非常关键概念,我们查看Include/cpython/unicodeobject.h源文件时,CPython内部定义了一个叫PyUnicode_Kind的枚举类型,PyUnicode_New函数在实例化一个字符串对象时,会使用PyUnicode_Kind的枚举值设定字符串对象内部类state.kind的值,该字段将告知CPython的其他内部代码如何解读C底层的char指针指...

Since the binary number has 7 digits, we can add leading zeros to form a full byte (8 bits) of binary notation: 01000001 This is the binary representation of the ASCII code for the letter 'A'. Why do we need to convert ASCII to binary?
