#58192 — How to get final URL after redirection

I have a link that will redirect to any-other link and i have to work with that final link.
For example if i have a link "www.bit.ly/2V6CFi" that will redirect to "www.google.com".
Here i want that i take "www.bit.ly/2V6CFi" and find the final redirect link and append "#q=python" to that link and produce an output that is "www.google.com/#q=python".

For bitly links you need to use their API:
http://dev.bitly.com/links.html#v3_expand

There is a python module for interacting with it:
https://github.com/bitly/bitly-api-python

I was only giving an example as bitly, actually i need to proceed with "http://www.mysmartprice.com/out/sendtostore.php?id=107120529&top_category=electronics&store=amazon&mspid=51889&category=computer&rk=30" this is the link that landed at "www.amazong.com" and i want write code that take this link and append something to the final landing link that is "www.amazon.com"

When asking a question, it really helps to ask the question you want to ask, not some other question which you think is similar :-)  Details matter.

The "normal" way a redirect is done is to return a 301 (or 302) status code, and include a Location: line in the HTTP response headers.  If that was the case, you would just do a GET on the url with a library like requests and examine the status code and headers in the response object you got back.

This URL, however, doesn't do that.  What it does do is include:

<meta http-equiv="Refresh"  content="0; url=http://amazon.in/gp/offer-listing/B00AF856T2/?/ref=as_li_tf_tl?ie=UTF8&camp=3626&creative=24790&creativeASIN=9380349300&linkCode=as2&tag=mysm-21">

in the body, which does kind of the same thing, but in a horrible way.  I suspect they do this provide a hook for the google analytics tracking code in the window.onload handler.  Unless you wanted to include a full HTML and javascript execution environment in your application, you're pretty much toast here.

You might look at the requests module:
http://www.python-requests.org/en/latest/api/

It has an 'allow_redirects' parameter that looks like you can set to
get the final url.  Haven't tried it

I can't imagine this does anything other than the 30x processing described above (which won't work in the OP's case because that's not the mechanism used).
