Come sit on the couch
Never mind. I guess I had been trying to make it more difficult than
it is. As a note, I can work on something for 10 hours and not figure
it out. But the second I post to a group, then I immediately figure
it out myself. Strange snake this Python...
Example for anyone else interested:

New to Python. I can solve the problem in perl by using "split()" to
an array. Can't figure it out in Python.
I'm reading variable lines of text. I want to use the first number I
find. The problem is the lines are variable.
Input example:
this is a number: 1
here are some numbers 1 2 3 4

And now for something completely different...
I see a lot of COM stuff with Python for excel...and I quickly made
the same program output to excel. What if the input file were a Word
document? Where is there information about manipulating word
documents, or what could I add to make the same prog

Wow, thank you all. All three work. To output correctly I needed to
add:
output.write("\r\n")
This is really a great help!!
Because of my limited Python knowledge, I will need to try to figure
out exactly how they work for future text manipulation and for my own
knowledge. Could you recommend

What is in `line`? Paul wrot
Thank you both for helping me out. I am still rather new to Python
and so I'm probably trying to reinvent the wheel here.
When I try to do Paul's response, I get
>>>tokens = line.strip().split()
[]
So I am not quite sure how to read line by line.
tokens = input.read().split() gets me all the in

Hi all,
I started Python just a little while ago and I am stuck on something
that is really simple, but I just can't figure out.
Essentially I need to take a text document with some chemical
information in Czech and organize it into another text file. The
information is always EINECS number, CAS
