How to fix a While Loop only running once : Im trying to calculate how long until India surpasses China in population, my while loop only executes the first iteration though.

I have tried setting a while loop to execute within the loop itself and it just became an infinite loop instead,i have tried indenting print within and outside the loop as well.

    while India<China :
         China += Cgrowth*China
         India += Igrowth*India
         count += 1

    print(count)

My output always ends in 1.
i did the math out and even after one loop the statement is still true, so why is print(count) being ran while the loops conditions are false?
