Hello, I have a trouble and I don't know how to solve it. I am working with molecules and each molecule has a number of atoms. I obtain each atom spliting the molecule.
Ok. It is fine and I have no problem with it. The problem is when I have to work with these atoms. These atoms usually are only a letter but, sometimes it can also contain one o more numbers. If they contein a number I have to manipulate them separately. If the number was allways the same I know how to identify them, for example, 1: atom = 'C1' if '1' in atom: print 'kk' But, how can I do to identify in '1' all possibilities from 1-9, I tried: if '[1-9]', \d,... Any comments, please?
