Python Program number $5.$

Write a Python function that calculates $f^{\text{'}}$ and its truncation error using the Three$-$Point Endpoint Formula. Your code should display $($for each value of $h)$ the approximation, the truncation error and the absolute error.

Test your code using $f(x)=\frac{1}{x^2},x_0=1\mathrm{.}2,h=0\mathrm{.}4,h=0\mathrm{.}2,h=0\mathrm{.}1,h=0\mathrm{.}05$
