Question

我正在使用Python 3.6编写数字根程序。通常会找到特定数字的数字根。

这是代码

def digital_root():
  n = input("Enter the number:")
  sum = 0
  integer = int(n)
  if len(n) == 1:
     print("The digital root of " + n + " is: " + n)
  else:
     for x in n:
       sum += int(x)
  return sum

print(digital_root())

当我的输入为38时，输出为11，而应为2。

您必须继续执行该过程，直到获得长度1。可以编写递归函数来做到这一点。

     var express = require('express');
     var app = express();
     var request=require("request");
    const bodyParser = require('body-parser');
    app.use(bodyParser.json());
     app.use(function(req, res, next) {
            res.header("Access-Control-Allow-Origin", "*");
            res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With,    Content-Type, Accept,clientSecret");
            res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,PATCH,DELETE,OPTIONS');

            next();
      });

      app.post("/push/v1/apps/:appID/devices",function(req,response){
                var appID=req.params.appID;
            var options={
                url:"https://pushapp.sampleapp.net/push/v1/apps/"+appID+"/devices",
                headers:{
                    'Content-Type':req.headers["content-type"],
                    'clientSecret':req.headers["clientsecret"]
                },
                body: JSON.stringify(req.body)
            }
               request.post(options,function(err,res,body){
                if(res.statusCode==201){  
                    response.sendStatus(201).json(JSON.parse(body));
                }
                else{
                    response.sendStatus(res.statusCode);
                }

            });

            });

您将需要编写一个循环来进行求和，直到只剩下一个数字为止。

示例：

def digital_root():
    n = input("Enter the number:")
    sum = 0
    integer = int(n)

    calculate = True

    while calculate:
        if len(n) == 1:
            print("The digital root of " + str(integer) + " is: " + n)
            calculate = False
        else:
            sum = 0
            for x in n:
                sum += int(x)
            n = str(sum)

    return sum


print(digital_root())

为什么我的功能没有给我数字的数字根？
