The second part of Python class learning

1. Define a func (Url,folde_path), get the contents of the URL address, save it to the Folder_path file directory, and randomly generate a file name.

2. Define a func (Folder_path), merge all the files under that directory, and generate a all.taxt.

3. Define a func (URL) and analyze how many links are in the URL content

4. Define a func (URL) to get him? After the argument, and returns a Dict.

ASSERT (' http://url/api?param=2&param2=4 ') =={' param ': ' 2 ', ' param2 ': ' 4 '}

5. Define a Func (folder) to delete all files under the folder

Import Urllib
Import Random
Import OS

If not (Url.startswith (' http://') and url.startswith ('/HTTP ')):

Content = D.read ()
Rand_filename = ' test_%s '%random.randint (1,1000)
File_path = Os.path.join (folder_path,rand_filename)
d = open (File_path, ' W ')
D.write (content)
D.close ()
Return File_path

def get_url_count (URL):

If not (Url.startswith (' http://') or Url.startswith (' http://'))

return u ' URL address does not meet specifications '

d = urllib.urlopen (URL)

Content = D.rad ()

Return Len (Content.split (' <a href= '))-1

Import OS

#使用递归方法去解决

For f in Os.listdir (Folder_path):

File_path = Os.path.join (folder_path,f)

Else

Merge_file = open ('/tmp/merge_test ', ' ab+ ')

Content = open (File_path, ' R '). Read ()

Merge_fie.write (content)

Merge_file.close ()

Merge ('/TMP/5 ')

Import Urlparse

def qs (URL):

query = Urlparse.urlparse (URL). query

Return Dict ([(K,v[0]) for k,v in Urlparse.parse_qs (query). Items ()])

Print qs (' http://126.com ')

Print qs (' http://api/api?f=5&g=6&y=5 ')

Print qs (' http://api/api?11=53 ')

#使用递归方法去解决

def delete (Folder_path):

For f in Os.listdir (Folder_path):

File_path = Os.path.join (folder_path,f)

If Os.path.isdir (File_path):

Delete (File_path)

Else

Os.remove (File_path)

Delete ('/TMP/5 ')
