我一直在网上搜索一段时间,似乎找不到任何东西.我基本上学习了几种语言,我只是想用不同的语言重新创建一个程序.

def read_one_file():
    f = open('C:\Python27\inventory.dat', 'r')
    invid = f.readline()
    stock = f.readline()
    published = f.readline()
    price = f.readline()
    invtype = f.readline()
    title = f.readline()
    author = f.readline()
    return invid, stock, published, price, invtype, title, author

read_one_file()

print "Update Number In Stock"
print "----------------------"
print "Item ID: ", invid

基本上我是在尝试读取文件,将数据吸收到变量中然后将这些变量传递给main(类？).当我归还它们时,它们仍然无法打印.当我在read_one_file之外初始化它们时,它们仍然没有返回正确的东西.

我正在尝试学习几种语言,因此我在不同语言上也会遇到同样的问题.这是我的代码:

def read_one_file():
    with open('C:\Python27\inventory.dat', 'r') as f:
        invid = f.readline().strip()
        invtype = f.readline().strip()
        price = f.readline().strip()
        stock = f.readline().strip()
        title = f.readline().strip()
        author = f.readline().strip()
        published = f.readline().strip()

        return invid, invtype, price, stock, title, author, published


def write_one_file(holdId, holdType, holdPrice, holdStock, holdTitle, holdAuthor, holdPublished):
    with open('C:\Python27\inventory.dat', 'w') as f:
        invid = holdId
        price = holdPrice
        newstock = holdStock
        published = holdPublished
        f.write("Item Id: %s\n" %invid)
        f.write("Item Type: %s\n" %holdType)
        f.write("Item Price: %s\n" %price)
        f.write("Number In Stock: %s\n" %newstock)
        f.write("Title: …

这是我的代码的开头:

 public partial class Form1 : Form
{
    static Random random = new Random();
    int prevnum;
    int currentnum;

    public int GenerateRandomNumber()
    {
        return random.Next(1, 1000);
    }
    public Form1()
    {
        int randomNumber = random.Next(1, 1000);
        InitializeComponent();

    }

    private void enterButton_Click(object sender, EventArgs e)
    {
        currentnum = Convert.ToInt32(guessBox.Text);

        if (randomNumber < currentnum)
        {
            warmOrColdLabel.Text = "Too High";

            if (currentnum > prevnum)
            {
                guessBox.BackColor = Color.Blue;
                prevnum = currentnum;
            }
            else
            {
                guessBox.BackColor = Color.Red;
                prevnum = currentnum;
            }
        }
        if (randomNumber > …
