[Tutor] How to pass arguments to struct.pack()?

[prasad rao]

Hello
     I am finding it difficult to pass arguments to struct.pack().
Please some one tell me how to do it.



>>> def structpack(alist):
             import struct
             a='%di'%len(alist)
             print a
             b=[a]
             print alist

             print b

             for x in alist:
                b.append(x)
                arg1=b[0]
                arg2=b[1:]


            return struct.pack.tuple(arg1,arg2)

>>> structpack([112, 114, 97, 115, 97, 100, 97, 32, 114, 97, 111, 32, 110])
13i
[112, 114, 97, 115, 97, 100, 97, 32, 114, 97, 111, 32, 110]
['13i']

Traceback (most recent call last):
  File "<pyshell#87>", line 1, in <module>
    pstruct([112, 114, 97, 115, 97, 100, 97, 32, 114, 97, 111, 32, 110])
  File "<pyshell#86>", line 16, in pstruct
    return struct.pack.tuple(b)
AttributeError: 'builtin_function_or_method' object has no attribute 'tuple'
