Question

请使用以下字符串：

/foo/1/bar/2/cat/bob

我需要将其解析为最终为的对象或数组：

foo = 1
bar = 2
cat = bob

Answer 1

＆＃13;

        if 'users input' in (command = to left):
            Left_new = input("How many places would you like to move left")))

        elif 'users input' in (command = right):
            Right_new = input("How many places would you like to move right")))

        elif 'users input' in (= to up):
           up_new = input("How many places would you like to move up")))

        elif 'users input' in (= down ):
            Down_new =input("How many places would you like to move down")))

        else:
            if  ( users input <9) or ( users input > 100 ):
                print("Sorry one of your inputs were invalid...")

＆＃13;

Answer 2

＆＃13;

const str = '/foo/1/bar/2/cat/bob/test/'

const parts = str.split('/')
  .filter(val => val !== '')

const obj = {}

for (let ii = 0; ii < parts.length; ii+=2) {
  const key = parts[ii]
  const value = parts[ii+1]
  obj[key] = !isNaN(value) ? Number(value) : value
}

console.log(obj)

＆＃13;

Answer 3

正则表达式是各种解析的首选工具：

＆＃13;

str = '/foo/1/bar/2/cat/bob'
obj = {};
str.replace(/(\w+)\/(\w+)/g, (...m) => obj[m[1]] = m[2]);
console.log(obj);

＆＃13;

Answer 4

只为了它的乐趣，

let str = "/foo/1/bar/2/cat/bob",
    arr = str.split("/"),
    obj = {};
arr.shift();
while (arr.length) obj[arr.shift()] = arr.shift();
