我写了一个python脚本来创建一个整数的二进制文件.
import struct
pos = [7623, 3015, 3231, 3829]
inh = open('test.bin', 'wb')
for e in pos:
inh.write(struct.pack('i', e))
inh.close()

它工作得很好,然后我尝试使用下面的代码读取'test.bin'文件.
import struct
inh = open('test.bin', 'rb')
for rec in inh:
pos = struct.unpack('i', rec)
print pos
inh.close()

但它失败并显示错误消息:
Traceback (most recent call last):
File "readbinary.py", line 10, in <module>
pos = struct.unpack('i', rec)
File "/usr/lib/python2.5/struct.py", line 87, in unpack
return o.unpack(s)
struct.error: unpack requires a string argument of length 4

我想知道如何使用这些文件阅读struct.unpack.
非常感谢,Vipin
