If I'm not mistaken your idea is referencing two columns: first column is your acid name and the later is your surface area.
Later you want to connect the surface area if you name the acid name.
If that what you want another question arises... is your acid name is unique.
If it is you can make dictionary types.
A csb
B dsk
C dsk
you can create
mydic = []
mydic['A'] = 'csb'
mydic['B'] = 'dsk'
mydic['C'] = 'dsk'
you have to transform the file into a list and after that start building the dictionary variable.
After this dictionary variable is filled. you can get the surface area by typing the acid name such as:
print mydic['A'] # will result 'csb'

Hi, just joined. I've got a question that I'm guessing there's a ridiculously easy answer to, but I'm having trouble (no excuses, I'm just dumb!)...
My problem is I want to make a string object into a reference to another object. To be more specific, I'm reading through a text file of amino acids. The first item on each line is the amino acid name, and a later item is its exposed surface area. For each amino acid, I want to add up the surface area as I go through the text file. So what I'm doing is, for each line, assigning the reference 'residue' to the amino acid name. I'd like to then make the string referred to by 'residue' (eg, 'CYS' or 'TRP') a reference to an object that I will subsquently increment by the surface area value.
Thanks for any help. Perhaps I just need to be pointed to a relevent thread or given the correct words to search for in the archives or manual.
