(Time Dilation) in Python

You have probably heard of a famous application of Einstein's Special Theory of Relativity, known as the Twin Paradox. An astronaut traveling in a spaceship at near-lightspeed will age slower than "usual", and will return to Earth younger than his/her twin, by an amount known as the Lorenz factor. This phenomenon has been verified using atomic clocks in orbit; the clock traveling at high speed reports a different time than an identical clock left on Earth. Mind-boggling. Find the appropriate formula to apply. Your Python program should:

Input the distance to a traveler's favorite star (the destination)

Input the traveler's planned speed

Calculate how long the trip will take from the traveler's perspective (i.e. how much will the traveler age?)

Note: you must use a function to perform the calculations
