Question

convert this code to Python and make sure you use chained map and filter as well.

https://book.pythontips.com/en/latest/map_filter.html

CODE BELOW IS IN JAVASCRIPT

let people = [
{name: "Amy", pounds_weight: 152, inches_height: 63},
{name: "Joe", pounds_weight: 120, inches_height: 64},
{name: "Tom", pounds_weight: 210, inches_height: 78},
{name: "Jim", pounds_weight: 180, inches_height: 68},
{name: "Jen", pounds_weight: 120, inches_height: 62},
{name: "Ann", pounds_weight: 252, inches_height: 63},
{name: "Ben", pounds_weight: 240, inches_height: 72},
];

//functions to convert pounds to kg and inches to meters
let poundstokg = (pounds)=> pounds * 0.453592;
let inchestometers = (inches)=> inches * 0.0254;

//add bmi function
let addbmi = (person) => {
person["bmi"] = poundstokg(person["pounds_weight"])/(inchestometers(person["inches_height"]) * inchestometers(person["inches_height"]));
return person;
}
//checks if the person is overweight
let isOverweight = (person) => (person["bmi"] >= 25.0 && person["bmi"] < 30);
//checks if the person is obese
let isObese = (person) => (person["bmi"] >= 30);
// array of overweight and obese people
let overweight_people = people.map(addbmi).filter(isOverweight);
let obese_people = people.map(addbmi).filter(isObese);

console.log(overweight_people);
console.log(obese_people);
