安装好python后的牛刀小试
问题1: 在应用python 模块 chardet 运行程序时,若出现ImportError: No module named
chardet问题2: UE没有python高亮着色
问题3:UserAgent获取
问题4:python程序出现乱码解决
代码片段 1
# coding:utf-8
# '''
# 贴吧代码拉取
# '''
import urllib2
import sys
import chardet
def load_page(url):
'''
根据url 加载页面
'''
user_agent="Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36"
headers = {"User-Agent": user_agent}
requ = urllib2.Request(url,headers = headers)
response = urllib2.urlopen(requ)
html = response.read()
return html
代码片段 2
def tieba (url,page_begin,page_end):
'''

'''
f = open('nihao.txt','w')
for i in range(page_begin,page_end+1):
pn = 50 * ( i - 1)
myUrl = url + str(pn)
print myUrl
html = load_page(myUrl)
f.write("==========第%d页=========" %(i))
f.write(html)
if i == page_end+1 :
f.close()
url = raw_input("请输入贴吧地址:")
page_begin = int(raw_input("请输入起始页码:"))
page_end = int(raw_input("请输入终止页码:"))
tieba (url,page_begin,page_end)
运行程序后发现,拉取的信息是乱码的。
解决方案:
更改代码片段 1
# coding:utf-8
# '''
# 贴吧代码拉取
# '''
import urllib2
import sys
import chardet
def load_page(url):
'''
根据url 加载页面
'''
user_agent="Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.87 Safari/537.36"
headers = {"User-Agent": user_agent}
requ = urllib2.Request(url,headers = headers)
response = urllib2.urlopen(requ)
html = response.read()
typeEncode = sys.getfilesystemencoding()
infoencode = chardet.detect(html).get('encoding','utf-8')
info = html.decode(infoencode,'ignore').encode(typeEncode)
return info
添加代码
typeEncode = sys.getfilesystemencoding()
infoencode = chardet.detect(html).get(‘encoding’,’utf-8’)
info = html.decode(infoencode,’ignore’).encode(typeEncode)

在编写这段代码出现的问题小结:
问题1: 在应用python 模块 chardet 运行程序时,若出现
Traceback (most recent call last):
File “tieba.py”, line 8, in
import chardet
ImportError: No module named chardet
解决方案:window下的python
由于下载的python并没有chardet模块导致的。
这个时候需要下载 chardet下载方式,点击chardet即可下载
下载后 解压缩 ,提取 chardet目录所有文件
将其所有内容copy放入\Python27\Lib\site-packages 新建chardet文件夹下
问题2: UE没有python高亮着色
解决方案:
下载对应的python着色 Python 2.6 & 3.0 (python26.uew)
http://www.ultraedit.com/downloads/extras/wordfiles.html
下载后将python26.uew 放到UE的workfile文件夹下,
workfile文件夹目录获取:
UE 选项卡 –>选择高级–>配置–>查找输入框输入 || 语法着色–>文档的完整目录名称就是 workfile的 path了,让后将下载的uew文件copy进去,重启UE,发现py文件的内容着色了,自动匹配查看方式。
问题3:UserAgent获取
<html>
<body>
<script type="text/javascript">
document.write("UserAgent: "
)
document.write(navigator.userAgent + "")
script>
body>
html>
