ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() with dating the fossil question

I tried to wrote a piece of code when given the percent of carbon is still C 14, which is 35% and to calculate when the fossil formed. I assume it is between half life and twice the half life, therefore the range I offered: However, I received an error msg

t=np.arange(5730,5730*2,1)    while t in range(5730,5730*2):      if 0.5**(t/5700)>0.35:          t+=1      else:          break          print(t)
