Subject: FW: [Tutor] extract specific column
Date: Wed, 12 Oct 2011 21:59:34 +0200








The thing is, I don't know where to start. I know how to open the attached 
file, but I don't know how to work inside the file. Is this a csv file? Do I 
need to use a split function? In what way should I look at the file? As a 
string? As lines?

Best,
Anna

Hi,





I'm a beginner at python and I'm trying to extract a specific column from a txt 
file ( see attached file). 





In the attached file I want to extract the entire column 



        
        
        
        
        pph2_prob (i.e. column 16). But I want to get all the values from that 
column without the headline  



        
        
        
        
        pph2_prob.

How do I accomplish that? 

Hi Anna,
We're more than happy to help, but we also would love to see what you've done 
so far. What have you tried so far? Can you get the entire column *with* the 
headline?


When you show the effort that you've taken, you'll find people are much more 
inclined to help - very few people here will do your work for you, but most of 
us are perfectly willing to point you in the right direction!
