[Tutor] How do I create a "loop until" looping structure?

[1 2]

Hi there,
  As shown in the codes below, I want to end the loop until the s is no
greater than -5 but I found there is no "do... loop until..." like C so
what should I do? I will write it in C's style

s,n = 0,1
do:
import math
s=s+(math.log((n+1)/(n+2))/math.log(2))
loop until s < -5
print(s)
