Magic number一般是指硬写到代码里的整数常量，数值是编程者自己指定的，其他人不知道数值有什么具体意义...
MAGIC_NUMBER = (3425).to_bytes(2, 'little') + b'\r\n' _RAW_MAGIC_NUMBER = int.from_bytes(MAGIC_NUMBER, 'little') # For import.c HEX_MAGIC_NUMBER = hex(_RAW_MAGIC_NUMBER) print(HEX_MAGIC_NUMBER) ps:3425就是Python 3.9a2的Magic Number,执行后可以得到0xa0d0d61,则对应二进制码是61...
无论是magic string还是magic number,统称为magic value,即,魔法值。 它们在代码中突然出现,直接使用,没有说明,无从追溯。 这对代码的可读性,可维护性都带来了负面效应。 拿个简单的例子来说,在python中,我们有时会使用zipfile来处理压缩文件,比如这样:z_file.writestr(z_name, data, zipfile.ZIP_DEFLATED) ...
Magic Number是4字节的二进制数据,我们找到对应的十进制数据后,通过以下代码得到相应的二进制数据 MAGIC_NUMBER = (3413).to_bytes(2,'little') +b'\r\n'_RAW_MAGIC_NUMBER =int.from_bytes(MAGIC_NUMBER,'little')# For import.c 3413就是Python 3.8b4的Magic Number,执行后可以得到0x0A0D0D55,则对应...
Clusters in systems as diverse as metal atoms, virus proteins, noble gases, and nucleons have properties that depend sensitively on the number of constituent particles. Certain numbers are termed ‘magic’ because they grant the system with closed shells and exceptional stability. To this point, ...
