elementary tuple question. (sorry)

[Steven W. Orr]

I have a tuple that I got from struct.unpack. Now I want to pass the data
from the returned tuple to struct.pack

>>fmt

'l 10l 11i h 4h c 47c 0l'

>>>struct.pack(fmt, tup)

Traceback (most recent call last):
File "<stdin>", line 1, in ?
struct.error: required argument is not an integer

What's the idiom to pass the data in tup?

TIA

Try

mystring = struct.pack(fmt, *tup)

import struct

fmt = "l l"
result = struct.pack(fmt, 12, 4)

t = (12, 4)
result = struct.pack(fmt, *t)
---------

The * unpacks the tuple.

there's an unpack().

>>struct.unpack(fmt,result)
