Intro to Computer Science - Python | Khan Academy - Program design: weights on Mars | Intro to CS - Python | Khan Academy

Code along with a software engineer in this worked example using if-elif-else statements. Apply chained conditionals with if, elf, and else branches to calculate an object's weight on other planets based on the gravitational force.
