How to read html from a url in python 3

PythonHtmlUrl

Python Problem Overview


I looked at previous similar questions and got only more confused.

In python 3.4, I want to read an html page as a string, given the url.

In perl I do this with LWP::Simple, using get().

A matplotlib 1.3.1 example says: import urllib; u1=urllib.urlretrieve(url). python3 can't find urlretrieve.

I tried u1 = urllib.request.urlopen(url), which appears to get an HTTPResponse object, but I can't print it or get a length on it or index it.

u1.body doesn't exist. I can't find a description of the HTTPResponse in python3.

Is there an attribute in the HTTPResponse object which will give me the raw bytes of the html page?

(Irrelevant stuff from other questions include urllib2, which doesn't exist in my python, csv parsers, etc.)

Edit:

I found something in a prior question which partially (mostly) does the job:

u2 = urllib.request.urlopen('http://finance.yahoo.com/q?s=aapl&ql=1')

for lines in u2.readlines():
    print (lines)

I say 'partially' because I don't want to read separate lines, but just one big string.

I could just concatenate the lines, but every line printed has a character 'b' prepended to it.

Where does that come from?

Again, I suppose I could delete the first character before concatenating, but that does get to be a kloodge.

Python Solutions


Solution 1 - Python

Note that Python3 does not read the html code as a string but as a bytearray, so you need to convert it to one with decode.

import urllib.request

fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()

mystr = mybytes.decode("utf8")
fp.close()

print(mystr)

Solution 2 - Python

Try the 'requests' module, it's much simpler.

#pip install requests for installation

import requests

url = 'https://www.google.com/'
r = requests.get(url)
r.text

Solution 3 - Python

urllib.request.urlopen(url).read() should return you the raw HTML page as a string.

Solution 4 - Python

import requests

url = requests.get("http://yahoo.com")
htmltext = url.text
print(htmltext)

This will work similar to urllib.urlopen.

Solution 5 - Python

Reading an html page with urllib is fairly simple to do. Since you want to read it as a single string I will show you.

Import urllib.request:

#!/usr/bin/python3.5

import urllib.request

Prepare our request

request = urllib.request.Request('http://www.w3schools.com')

Always use a "try/except" when requesting a web page as things can easily go wrong. urlopen() requests the page.

try:
	response = urllib.request.urlopen(request)
except:
	print("something wrong")
	

Type is a great function that will tell us what 'type' a variable is. Here, response is a http.response object.

print(type(response))

The read function for our response object will store the html as bytes to our variable. Again type() will verify this.

htmlBytes = response.read()

print(type(htmlBytes))

Now we use the decode function for our bytes variable to get a single string.

htmlStr = htmlBytes.decode("utf8")

print(type(htmlStr))

If you do want to split up this string into separate lines, you can do so with the split() function. In this form we can easily iterate through to print out the entire page or do any other processing.

htmlSplit = htmlStr.split('\n')

print(type(htmlSplit))

for line in htmlSplit:
	print(line)

Hopefully this provides a little more detailed of an answer. Python documentation and tutorials are great, I would use that as a reference because it will answer most questions you might have.

Solution 6 - Python

For python 2

import urllib
some_url = 'https://docs.python.org/2/library/urllib.html'
filehandle = urllib.urlopen(some_url)
print filehandle.read()
