我现在读取了芯片的数据，但是它是二进制流。我想把它print出来，怎么处理呢？
基因芯片吗？affy的cel文件可以用r来读的。
binascii — Convert between binary and ASCII
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.
struct模块可以对二进制数据进行解析和封装的功能，参考：
