need help with python.

can modify/ refer from the code below

import numpy as np; from pylab import *;
import scipy.optimize
hdata=[3.24, 2.68, 2.35, 1.87, 2.57,2.77]
tdata=[0.81, 0.74, 0.69, 0.61, 0.72, 0.75];
error_in_t=np.ones(6)*0.1

def t(h,g):
return (2*h/g)**0.5

results=scipy.optimize.curve_fit(t,hdata,tdata,sigma=error_in_t,absolute_sigma=True)

gbest=results[0][0];
var=results[1][0][0];
se=var**0.5

Q1 Measuring gravity by dropping a ball in a vacuum
In an experiment, a ball was dropped through a vertial distnace from rest. The vertical distance tranversed and the corresponding time interval
measured at these distances were 3.24, 2.68, 2.35, 1.87, 2.57,2.77 meters, with the corresponding time intervals 0.81, 0.74, 0.69, 0.61, 0.72,
0.75 seconds. The time intervals are measured with an error bar of 0.1 second. Determine the best-fit value of g by fitting the data points
against the formula h = gt² by taking into accont the error in time the time interval. Be reminded that the argument 'sigma' and
'absolut_sigma=True' in scipy.optimize.curve_fit() are associated with the error bar in h (not At).
Hint : You have to calculate Ah for each pair of h;, t;.
