This will probably do it:

    from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler
    
    class MyHandler(BaseHTTPRequestHandler):
        def do_GET(self):
            self.send_response(200)
            self.send_header(&#39;Content-type&#39;, &#39;text/html&#39;)
            self.end_headers()
            self.wfile.write(&#39;&lt;html&gt;&lt;body&gt;&lt;p&gt;OK&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;&#39;)
        def log_message(self, format, *args):
            return
    
    httpd = HTTPServer((&#39;&#39;, 8001), MyHandler)
    httpd.serve_forever()


How do I install the bcmath module on a server? I tried

I have created a database for my android app which contains static data and does not require update/delete functionality thus when the app starts, I want to check if the db exists and if not then execute my dbAdapter class. I know its a simple if statement but I was just wondering the most efficient way to query whether the db exists. 

Cheers

I am writing a simple http server as part of my project. Below is a skeleton of my script:

    from BaseHTTPServer import HTTPServer, BaseHTTPRequestHandler

    class MyHanlder(BaseHTTPRequestHandler):
        def do_GET(self):
            self.send_response(200)
            self.send_header(&#39;Content-type&#39;, &#39;text/html&#39;)
            self.end_headers()
            self.wfile.write(&#39;&lt;html&gt;&lt;body&gt;&lt;p&gt;OK&lt;/p&gt;&lt;/body&gt;&lt;/html&gt;&#39;)

    httpd = HTTPServer((&#39;&#39;, 8001), MyHanlder)
    httpd.serve_forever()

My question: how do I suppress the stderr log output my script produces every time a client connects to my server? 

I have looked at the HTTPServer class up to its parent, but was unable to find any flag or function call to achieve this. I also looked at the BaseHTTPRequestHandler class, but could not find a clue. I am sure there must be a way. If you do, please share with me and others; I appreciate your effort.

How can I check if any of the strings in an array exists in another string?

Like:

    a = [&#39;a&#39;, &#39;b&#39;, &#39;c&#39;]
    str = &quot;a123&quot;
    if a in str:
      print &quot;some of the strings found in str&quot;
    else:
      print &quot;no strings found in str&quot;

That code doesn&#39;t work, it&#39;s just to show what I want to achieve.

What is an efficient way to repeat a string to a certain length? Eg: `repeat(&#39;abc&#39;, 7) -&gt; &#39;abcabca&#39;`

Here is my current code:

    def repeat(string, length):
        cur, old = 1, string
        while len(string) &lt; length:
            string += old[cur-1]
            cur = (cur+1)%len(old)
        return string

Is there a better (more pythonic) way to do this? Maybe using list comprehension?

If I have an array like

    a = np.array([2, 3, -1, -4, 3])

I want to set all the negative elements to zero: `[2, 3, 0, 0, 3]`. How to do it with numpy without an explicit for? I need to use the modified `a` in a computation, for example

    c = a * b

where `b` is another array with the same length of the original `a`

Conclusion
==========

    import numpy as np
    from time import time

    a = np.random.uniform(-1, 1, 20000000)
    t = time(); b = np.where(a&gt;0, a, 0); print (&quot;1. &quot;, time() - t)
    a = np.random.uniform(-1, 1, 20000000)
    t = time(); b = a.clip(min=0); print (&quot;2. &quot;, time() - t)
    a = np.random.uniform(-1, 1, 20000000)
    t = time(); a[a &lt; 0] = 0; print (&quot;3. &quot;, time() - t)
    a = np.random.uniform(-1, 1, 20000000)
    t = time(); a[np.where(a&lt;0)] = 0; print (&quot;4. &quot;, time() - t)
    a = np.random.uniform(-1, 1, 20000000)
    t = time(); b = [max(x, 0) for x in a]; print (&quot;5. &quot;, time() - t)

Is there a way to, for example, print `Hello World!` every n seconds?
For example, the program would go through whatever code I had, then once it had been 5 seconds (with `time.sleep()`) it would execute that code. I would be using this to update a file though, not print Hello World.

For example:

    startrepeat(&quot;print(&#39;Hello World&#39;)&quot;, .01) # Repeats print(&#39;Hello World&#39;) ever .01 seconds

    for i in range(5):
        print(i)

    &gt;&gt; Hello World!
    &gt;&gt; 0
    &gt;&gt; 1
    &gt;&gt; 2
    &gt;&gt; Hello World!
    &gt;&gt; 3
    &gt;&gt; Hello World!
    &gt;&gt; 4

I want to be able to set a single cookie, and read that single cookie with each request made to the nodejs server instance. Can it be done in a few lines of code, without the need to pull in a third party lib?

    var http = require(&#39;http&#39;);
    
    http.createServer(function (request, response) {
      response.writeHead(200, {&#39;Content-Type&#39;: &#39;text/plain&#39;});
      response.end(&#39;Hello World\n&#39;);
    }).listen(8124);
    
    console.log(&#39;Server running at http://127.0.0.1:8124/&#39;);

Just trying to take the above code directly from nodejs.org, and work a cookie into it.

Is there a way to create a very basic HTTP server (supporting only GET/POST) in Java using just the Java SE API, without writing code to manually parse HTTP requests and manually format HTTP responses? The Java SE API nicely encapsulates the HTTP client functionality in `HttpURLConnection`, but is there an analog for HTTP server functionality?

Just to be clear, the problem I have with a lot of `ServerSocket` examples I&#39;ve seen online is that they do their own request parsing/response formatting and error handling, which is tedious, error-prone, and not likely to be comprehensive, and I&#39;m trying to avoid it for those reasons.

What is the Python 3 equivalent of `python -m SimpleHTTPServer`?


What is the Python 3 equivalent of &quot;python -m SimpleHTTPServer&quot;

Python&#39;s [http.server](https://docs.python.org/3/library/http.server.html) (or SimpleHTTPServer for Python 2) is a great way of serve the contents of the current directory from the command line:

    python -m http.server

However, as far as web servers go, it&#39;s very slooooow...

It behaves as though it&#39;s single threaded, and occasionally causes timeout errors when loading JavaScript AMD modules using RequireJS. It can take five to ten seconds to load a simple page with no images.

What&#39;s a faster alternative that is just as convenient?

I&#39;m using the npm package &quot;http-server&quot; (https://www.npmjs.com/package/http-server) to set up a simple webserver, but I cannot get it to use SSL. My command in package.json is

    http-server -p 8000 -o -S

with a cert.pem and key.pem in my root directory (for now). The &quot;-o&quot; option opens a browser to the default page, but the page is served using HTTP and not even accessible through HTTPS. I don&#39;t get any errors or warnings. I&#39;ve also tried adding the &quot;-C&quot; and &quot;-K&quot; options without luck. Has any one had any success with this package?

In the `do_POST()` method of `BaseHTTPRequestHandler` I can access the headers of the POST request simply via the property `self.headers`. But I can&#39;t find a similar property for accessing the body of the message. How do I then go about doing that?


How to extract HTTP message body in BaseHTTPRequestHandler.do_POST()?

I am trying to make a BaseHTTPServer program. I prefer to use Python 3.3 or 3.2 for it. I find the doc hard to understand regarding what to import but tried changing the import from:

    from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer

to:

    from http.server import BaseHTTPRequestHandler,HTTPServer

and then the import works and the program start and awaits a GET request. BUT when the request arrives an exception is raised:

    File &quot;C:\Python33\lib\socket.py&quot;, line 317, in write return self._sock.send(b)
    TypeError: &#39;str&#39; does not support the buffer interface

Question: Is there a version of BaseHTTPServer or http.server that works out of the box with Python3.x or am I doing something wrong?

This is &quot;my&quot; program that I try running in Python 3.3 and 3.2:

    #!/usr/bin/python
    # from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer
    from http.server import BaseHTTPRequestHandler,HTTPServer
    
    PORT_NUMBER = 8080
    
    # This class will handle any incoming request from
    # a browser 
    class myHandler(BaseHTTPRequestHandler):
    
        # Handler for the GET requests
        def do_GET(self):
            print   (&#39;Get request received&#39;)
            self.send_response(200)
            self.send_header(&#39;Content-type&#39;,&#39;text/html&#39;)
            self.end_headers()
            # Send the html message
            self.wfile.write(&quot;Hello World !&quot;)
            return

    try:
    	# Create a web server and define the handler to manage the
    	# incoming request
     	server = HTTPServer((&#39;&#39;, PORT_NUMBER), myHandler)
    	print (&#39;Started httpserver on port &#39; , PORT_NUMBER)
    
    	# Wait forever for incoming http requests
    	server.serve_forever()

    except KeyboardInterrupt:
    	print (&#39;^C received, shutting down the web server&#39;)
    	server.socket.close()

The Program work partly in Python2.7 but gives this exception after 2-8 requests:

    error: [Errno 10054] An existing connection was forcibly closed by the remote host
