如何将我的python代码作为脚本运行

I am new to python so please bear with me. I want to create python code that solves captcha online. I am developing in windows not linux and right now though I have many problems.

我是python的新手所以请耐心等待。我想创建在线解决验证码的python代码。我在windows中开发而不是linux，现在虽然我有很多问题。

1st I cannot understand how will my python file run on a live website. Solve captcha that a website shows.

1我无法理解我的python文件将如何在实时网站上运行。解决网站显示的验证码。

2nd I have managed to develope and get some code but I don't think it works properly or at least the way I want it too. When I ran it withe the cmd nothing happens.

第二，我已经设法开发并获得了一些代码，但我认为它不能正常工作或至少我想要的方式。当我用cmd运行它没有任何反应。

Here is my code:

这是我的代码：

from PIL import Image
import ImageEnhance
from pytesser import *
from urllib import urlretrieve

def get(link):
    urlretrieve(link,'temp.png')

get('http://www.example.com/');
im = Image.open("temp.png")
nx, ny = im.size
im2 = im.resize((int(nx*5), int(ny*5)), Image.BICUBIC)
im2.save("temp2.png")
enh = ImageEnhance.Contrast(im)
enh.enhance(1.3).show("30% more contrast")

imgx = Image.open('temp2.png')
imgx = imgx.convert("RGBA")
pix = imgx.load()
for y in xrange(imgx.size[1]):
    for x in xrange(imgx.size[0]):
        if pix[x, y] != (0, 0, 0, 255):
            pix[x, y] = (255, 255, 255, 255)
imgx.save("bw.gif", "GIF")
original = Image.open('bw.gif')
bg = original.resize((116, 56), Image.NEAREST)
ext = ".tif"
bg.save("input-NEAREST" + ext)
image = Image.open('input-NEAREST.tif')
print image_to_string(image)

Can someone please help me try to fix this code and explain to me how to use it e.x on a website

有人可以帮我尝试修复此代码并向我解释如何在网站上使用它e.x

I cannot understand how will my python file run on a live website.

我无法理解我的python文件将如何在实时网站上运行。

I think I can help you understand. You don't run your python script "on a live website". What you want is to run you python script locally on your machine, but as part of a bigger program that behaves as an automated client designed to interact with the server whose captchas you're cracking.

我想我可以帮助你理解。您不“在实时网站上”运行您的python脚本。你想要的是在你的机器上本地运行你的python脚本，但作为一个更大的程序的一部分，行为作为一个自动客户端，旨在与你的破解验证码的服务器进行交互。

Compare these two programs:

比较这两个程序：

Google Chrome is a human guided web client, and it can interact with any web server.
Google Chrome是一款人性化的网络客户端，可以与任何网络服务器进行互动。
Your script is an automated client, and it can interact only with the web server you design it to.
您的脚本是一个自动客户端，它只能与您设计的Web服务器进行交互。

Here's what I mean by specific design: you design your client to get captcha images from a specific URL for the web server, and to submit data in a format specific to the web server. Like this, for instance:

以下是具体设计的含义：您设计客户端以从Web服务器的特定URL获取验证码图像，并以特定于Web服务器的格式提交数据。像这样，例如：

Loads the website you want with something like httplib performing an HTTP GET.
使用httplib执行HTTP GET之类的东西加载您想要的网站。
Extracts the captcha image and solves it
提取验证码图像并解决它
Submits the form with the solved captcha string and the rest of your desired data, again with an http client like httplib performing an HTTP POST. (A POST is the same thing that the "submit" button does when you fill out a form on a website.)
使用已解决的验证码字符串和其他所需数据提交表单，再次使用httplib等http客户端执行HTTP POST。（当你在网站上填写表格时，POST与“提交”按钮的功能相同。）

Your current script does part of #1 - but it only extracts the image, it doesn't get the rest of the page. And if your preprocessing and image_to_string function work, then #2 is done.

您当前的脚本是＃1的一部分 - 但它只提取图像，它不会获取页面的其余部分。如果你的预处理和image_to_string函数工作，那么＃2就完成了。
