I don't follow what you mean by 'How do I report that the “3D Val” is
not present for that particular
record “8866W2310089.txt”?'
The obvious answer would be (assuming the filename is currently set to
“8866W2310089.txt”):
print('3D Val not present in %s' % filename)
I wonder if your actual question is:
1) How do I detect that it is not present? - check for a line starting
with '3D' while reading the file.
2) How do I mark it is not being present in my data structure? -
depends what kind of data structure you are using. A common idiom
would be to simply use the value None as a place-holder for situations
where the value is not supplied.
3) Something else...
