Question

我试图为rand range语句添加一个用户输入，并在列表中添加它将要排序的总数，我已尽力解决这个问题，但似乎没有任何工作正常。

import time
import random
def create_random_values():
    totalsortnum = (eval("Please enter the amount of numbers you wish to sort: "))

    rng1 = (eval("Please enter the maximum number range: "))
    randomList=[]
    for i in range (totalsortnum):
        randomList.append(random.randrange(1,rng1))
    return randomList, totalsortnum, rng1


def main():
    numList = create_random_values()
    print()
    print("Here is a random list of 20 numbers between 1 and 1000:")
    print(numList)

    pause = input("Hit <Enter> to start sorting")

    timeInitial = time.time()
    l = len(numList)
    for lastitem in range(l-1,0,-1):
        sorted = True
        for i in range(lastitem):
            if numList[i] > numList[i+1]:
                numList[i],numList[i+1] = numList[i+1],numList[i]
                sorted = False
            #print(numList)
            #pause = input("Hit <Enter> to start sorting")      
        if sorted == True:
            break
    timeFinal = time.time()
    print(numList)

    print("the selection sort of",len(numList),"items took:")
    print(timeFinal - timeInitial,"seconds.")

您的代码存在一些问题：

在create_random_values()内部，您尝试使用eval()进行用户输入 eval()不是您想要的功能，您需要input()。

main() numList内部的(randomList, totalsortnum, rng1)变量是一个3元组，randomList，我认为你只想引用import time import random def create_random_values(): totalsortnum = int(input("Please enter the amount of numbers you wish to sort: ")) rng1 = int(input("Please enter the maximum number range: ")) randomList=[] for i in range (totalsortnum): randomList.append(random.randrange(1,rng1)) return randomList, totalsortnum, rng1 def main(): numList, totalsortnum, rng1 = create_random_values() print() print("Here is a random list of {0} numbers between 1 and {1}:".format(totalsortnum, rng1)) print(numList) pause = input("Hit <Enter> to start sorting") timeInitial = time.time() l = len(numList) for lastitem in range(l-1,0,-1): sorted = True for i in range(lastitem): if numList[i] > numList[i+1]: numList[i],numList[i+1] = numList[i+1],numList[i] sorted = False print(numList) #pause = input("Hit <Enter> to start sorting") if sorted == True: break timeFinal = time.time() print(numList) print("the selection sort of",len(numList),"items took:") print(timeFinal - timeInitial,"seconds.")。

这应该适合你：

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class PlayerController : MonoBehaviour {

    public float speed = 12f, jumpHeight = 30f;
    Rigidbody2D playerBody;
    Transform playerTrans, tagGround;
    bool isGrounded = false;
    public LayerMask playerMask;
    public float maxJumps = 2;
    public float jumpsLeft = 2;



    // Use this for initialization
    void Start ()
    {
        playerBody = this.GetComponent<Rigidbody2D>();
        playerTrans = this.transform;
        tagGround = GameObject.Find(this.name + "/tag_Ground").transform;

    }

    // Update is called once per frame
    public void FixedUpdate ()
    {
        isGrounded = Physics2D.Linecast(playerTrans.position, tagGround.position, playerMask);
        Move();
        Jump();
        DoubleJump();

    }

    private void Move()
    {
        float move = Input.GetAxisRaw("Horizontal") * speed;
        playerBody.velocity = new Vector2(move, playerBody.velocity.y);
    }

    private void Jump()

    {
        if (isGrounded)
        {


            if (Input.GetButtonDown("Jump"))
            {
                playerBody.velocity = new Vector2(playerBody.velocity.x, jumpHeight);


            }


        }

    }
    private void DoubleJump()
    {
        if (Input.GetButtonDown("Jump") && jumpsLeft > 0)
        {
            Jump();
            jumpsLeft--;
        }

        if (isGrounded)
        {
            jumpsLeft = maxJumps;
        }
    }
}

变量在冒泡排序程序中的rand range语句中不起作用
