[Python] [25] [experimental demo includes exercises]

Original title:

A sequence Score: 2 / 1,3 / 2,5 / 3,8 / 5,13 / 8,21 / 13 ... and this calculated front 20 of the series.

#   has a sequence Score: 2 / 1,3 / 2,5 / 3,8 / 5,13 / 8 21/13 ... and this is determined before the series of 20. 

m = [1,2 ] 
n- = [2,3 ] 
S = 0
 for I in Range (20 is ):
     IF (len (m) <+ I. 1 ): 
        m.append (m [I -1] + m [ 2-I ]) 
        n.append (n-[I -1] n-+ [I-2 ]) 
    
    S = S n-+ [I] / m [I] 

Print ( " ########### ## " , S, " \ the n- ",m,"\n",n)

o = [1,2]
t = 0
for i in range(0,20):
    if i >=1:
        o.append(o[i-1]+o[i])
    t = t + o[i+1]/o[i]

print("t",t)
