Typically, you would use either a list or a dict to simulate something like that: # list g = [1, 2, 4, 8, 16] print g[3] # dictionary h = {} h[0] = 1 h[1] = 2 h[2] = 4 h[3] = 8 h[4] = 16 print h[3] The difference is that a list needs elements starting at index 0 and without any gaps, while a dictionary can contain "holes". Please refer to any beginners' Python tutorial for info on these types. Concerning the other formulas you posted, those ended up as completely illegible here for the complete lack of formatting. Explaining things in plain English along with the mathematics would be a good idea, IMHO. Good luck!
