Okay I'm having a few issues with this and I can't seem to get it sorted
out (most likely due to my inexperience with Python).
Here is my Python code:
def fileInput():
data = []
s = raw_input("Please enter the filename to process (enter full path if
not in current directory): ")
(in general, it's not a good idea mixing the user interfase with data
processing - I'd make the filename a parameter for this function. But this
has nothing to do with your main issue.)
fd = open(s, "r")
fd.readline()
line = fd.readlines()
for record in line:
I'd replace the above two lines with:
for record in fd:
record = record.strip()
items = record.split(',')
for i in range(1, 5):
items[i] = float(items[i])
items[5] = int(items[5])
data.append(items)
fd.close()
return items
`return items` or `return data`? Are you only interested on the *last*
line in the file? If so, I'd skip processing all previous lines...
It works perfectly and does exactly what I want it to do. The problem
comes when I try and convert the data I returned from the Python script
and turn it into something useable in C.
I have no idea. The C functions that seem most use deal with Tuples,
when this is a list and I can't see any specific functions for dealing
with lists in the C API. Can anyone give me some pointers in the right
direction at all please? I know the C program has received the data
correctly, I just need to put it in C types.
Uh? You have a complete API for working with list objects, the functions
named PyList_*
See http://docs.python.org/api/listObjects.html
There is also an abstract layer that works both with lists and tuples:
http://docs.python.org/api/sequence.html
If that's not what you are after, please provide more details...
