1. Java有Quartz這個強大的排程套件，Python當然也有=>Advanced Python Scheduler (APScheduler)
2. 簡單的http client (Python3以前是httplib)

import http.client

conn = http.client.HTTPConnection("www.google.com.tw")  
conn.request('GET', '/')  
r1 = conn.getresponse() 
print(r1.status, r1.reason) #正常的話會印出 200 OK
conn.close()

import hashlib
md5 = hashlib.md5()
#官網 Note : Feeding string objects is to update() is not supported, as hashes work on bytes, not on characters.
md5.update(b"This is a book")#因為上述，所以字串前多加一個b
print(md5.digest())  #加密後用二進位表示  
print(md5.hexdigest()) #加密後用十六進位表示  
#第7,9,11合在一起成下列寫法
print(hashlib.new("md5", b"This is a book").hexdigest())
