Python的ctypes 和pyinstaller

这几天在学习python的爬虫， 无意中看到一篇博文 Python爬虫之自制英汉字典 发现里面的ctypes 和pyinstaller 还不了解，这边文章说白了就是你输入英文， python读取你的输入 然后发送一个http请求到有道翻译，然后把翻译的结果打印出来，这里使用了ctypes来设置打印窗口的颜色，使用pyinstaller来打包python程序， 网上关于pyinstaller和ctypes介绍已经很多了

Python打包方法——Pyinstaller

Python使用pyinstaller打包几个小技巧

python ctypes 探究 ---- python 与 c 的交互

Python ctypes 模块

代码如下：

import requests

from bs4 import BeautifulSoup

import random

import ctypes

STD_INPUT_HANDLE = -

STD_OUTPUT_HANDLE = -

STD_ERROR_HANDLE = -

FOREGROUND_DARKBLUE = 0x01  # 暗蓝色

FOREGROUND_DARKGREEN = 0x02  # 暗绿色

FOREGROUND_DARKSKYBLUE = 0x03  # 暗天蓝色

FOREGROUND_DARKRED = 0x04  # 暗红色

FOREGROUND_DARKPINK = 0x05  # 暗粉红色

FOREGROUND_DARKYELLOW = 0x06  # 暗黄色

FOREGROUND_DARKWHITE = 0x07  # 暗白色

FOREGROUND_DARKGRAY = 0x08  # 暗灰色

FOREGROUND_BLUE = 0x09  # 蓝色

FOREGROUND_GREEN = 0x0a  # 绿色

FOREGROUND_SKYBLUE = 0x0b  # 天蓝色

FOREGROUND_RED = 0x0c  # 红色

FOREGROUND_PINK = 0x0d  # 粉红色

FOREGROUND_YELLOW = 0x0e  # 黄色

FOREGROUND_WHITE = 0x0f  # 白色

std_out_handle = ctypes.windll.kernel32.GetStdHandle(STD_OUTPUT_HANDLE)

# 设置文字颜色

def set_cmd_text_color(color, handle=std_out_handle):

    return ctypes.windll.kernel32.SetConsoleTextAttribute(handle, color)

# 重置文字颜色为白色

def reset_color():

    set_cmd_text_color(FOREGROUND_DARKWHITE)

# 以指定颜色输出文字

def cprint(mess, color):

    color_dict = {'暗蓝色': FOREGROUND_DARKBLUE,

                  '暗绿色': FOREGROUND_DARKGREEN,

                  '暗天蓝色': FOREGROUND_DARKSKYBLUE,

                  '暗红色': FOREGROUND_DARKRED,

                  '暗粉红色': FOREGROUND_DARKPINK,

                  '暗黄色': FOREGROUND_DARKYELLOW,

                  '暗白色': FOREGROUND_DARKWHITE,

                  '暗灰色': FOREGROUND_DARKGRAY,

                  '蓝色': FOREGROUND_BLUE,

                  '绿色': FOREGROUND_GREEN,

                  '天蓝色': FOREGROUND_SKYBLUE,

                  '红色': FOREGROUND_RED,

                  '粉红色': FOREGROUND_PINK,

                  '黄色': FOREGROUND_YELLOW,

                  '白色': FOREGROUND_WHITE

                  }

    set_cmd_text_color(color_dict[color])

    print(mess)

    reset_color()

# 颜色列表

color_list = ['暗蓝色','暗绿色','暗天蓝色','暗红色','暗粉红色','暗黄色','暗白色','暗灰色','蓝色','绿色','天蓝色','红色','粉红色','黄色','白色']

# print information of this application

print('#'*)

print('This app is used for translating English word to Chineses!')

print('#'*+'\n')

# get word from Command line

word = input("Enter a word (enter 'q' to exit): ")

# main body

while word != 'q': # 'q' to exit

    try:

        # 利用GET获取输入单词的网页信息

        r = requests.get(url='http://dict.youdao.com/w/%s/#keyfrom=dict2.top' % word)

        # 利用BeautifulSoup将获取到的文本解析成HTML

        soup = BeautifulSoup(r.text, "lxml")

        # 获取字典的标签内容

        s = soup.find(class_='trans-container')('ul')[]('li')

        # 随机选择输出的颜色

        random.shuffle(color_list)

        # 输出字典的具体内容

        for item in s:

            if item.text:

                cprint(item.text, color_list[])

        print('=' *  + '\n')

    except Exception as e:

        print("Sorry, there is a error!\n"+e)

    finally:

        word = input("Enter a word (enter 'q' to exit): ")

打包如下：
