VERY EASY SOLUTION **

def funnyString(s): r=s[::-1] x=list(s) a=list(r) for i in range(len(x)): x[i]=ord(x[i]) for j in range(len(a)) : a[j]=ord(a[j])

i=0
j=1
while j<len(x):
    x[i]=abs(x[j]-x[i]) 
    a[i]=abs(a[j]-a[i])
    i=j
    j=j+1

x.pop(j-1)
a.pop(j-1)

if x==a:
    return "Funny"
else:
    return "Not Funny"
