binascii.b2a_hex(data) binascii.hexlify(data) Return the hexadecimal representation of the binary data. Every byte of data is converted into the corresponding 2-digit hex representation. The resulting string is therefore twice as long as the length of data.
binascii.a2b_hex(hexstr) binascii.unhexlify(hexstr) Return the binary data represented by the hexadecimal string hexstr. This function is the inverse of b2a_hex(). hexstr must contain an even number of hexadecimal digits (which can be upper or lower case), otherwise a TypeError is raised.

之前模仿java的Bytebuffer写的一个读取/写入 字节数组的类,希望对你有帮助

struct模块中的pack和unpack函数.
基因芯片吗？affy的cel文件可以用r来读的。
struct模块可以对二进制数据进行解析和封装的功能，参考：
