Exercise Modify this script to improve its readability and to not repeat common math operations. Add two new variables named half_wheelbase and half_track. Use the corresponding mathematical calculation to set these variables equal to half the value of the wheelbase and the track variables accordingly. Replace the repeating mathematical operations in the translation commands with the use of these two variables.
