Let's look at a simple example:

# One of the easiest reptiles small program, just to get to the end of the html source file

Requests Import 
URL1 = "https://live.500.com/" the ISO-8859-1 # 
URL2 = "https://www.baidu.com/" the ISO-8859-1 # 
URL3 = "HTTPS: // Study .163.com / Course, / introduction.htm? courseId # = 1,209,448,892 / courseDetail? the Tab = 1 "# UTF-8 
URL4 =" http://www.cwl.gov.cn/kjxx/ssq/kjgg/ "# ISO -8859-1 
Re = requests.get (URL3) 
IF re.status_code == 200: # If the request succeeds, it returns a status code is 200. 
    # Indicates that the request is successful, you can continue to go below 
    # print (re.text) # may be garbled because the encoding issue 
    # print (re.encoding) # get-8 character encoding or ISO-UTF 8859-1 
    IF Re. encoding == "ISO-8859-1": # If this is coded, it should be the character set gb2312, we must turn about code, otherwise there will be Chinese garbled　　　　　　　　　　　　　　
        html = re.text.encode ( "ISO-8859-1 ") .decode (" GBK ") # encoded first, and then decoding 
    the else: 
        HTML = re.
    Print (HTML) 
the else: # request was unsuccessful. 
    print ( "access fails, try another URL bar!") 

#_________________________________________________________________________________________

re.text # returns the character type 
re.content # returns a byte type, for this type of picture, ah, ah sound, video, etc.

The above example is a get request requests issued library, a post request may be transmitted: 
Re = requests.post (URL3, Data = { "Key": "value"}) with a parameter dictionary to #.
