Python Requests Recreate Post Request with Cookies

So I was looking at my chrome console for a post request that I was making, and there is a 'cookie' value in the header file that has this data:

strTradeLastInventoryContext=730_2; bCompletedTradeOfferTutorial=true; steamMachineAuth76561198052177472=3167F37117************B82C2E; steamMachineAuth76561198189250810=E292770040E************B5F97703126DE48E; rgDiscussionPrefs=%7B%22cTopicRepliesPerPage%******%7D; sessionid=053257f1102e4967e2527ced; steamCountry=US%7C708d3************e569cc75495; steamLogin=76561198052177472%7C%7C4EC6FBDFA0****************12DE568; steamLoginSecure=765611*********************44BEC4E8BDA86264E; webTradeEligibility=%7B%22allowed%22%3A1%2C%22allowed_at_time%22%3A0%2C%22steamguard_required_days%22%3A15%2C%22sales_this_year%22%3A9%2C%22max_sales_per_year%22%3A200%2C%22forms_request***************cooldown_days%22%3A7%7D; strInventoryLastContext=730_2; recentlyVisitedAppHubs=42700%2C2***********930%2C440; timezoneOffset=-14400,0; __utma=268881843.1147920287.1419547163.1431887507.1431890089.151; __utmb=268881843.0.10.1431890089; __utmc=268881843; __utmz=268881843.1431885538.149.94.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=(not%20provided)

I starred out some of the cookie's data so my trade account couldn't be robbed, but you should get the point. How should I go about recreating the cookie? Like should I create a dict with the keys being the values before the '=' in the cookie and the value being what comes after the '=' sign? Sorry if the question is unclear, I'm not sure how to go about doing this. Any help would be great!

Ex. cookie = {strTradeLastInventoryContext: 730_2, ...}

You may want to look at the requests documentation for cookies. You are right in that the cookie value is passed to the get call as a dictionary key/value.

cookies = {'cookie_key': 'somelongstring'}
requests.get(url, cookies=cookies)

There are really two options here.

If you happen to have the exact Cookie header you want to reproduce exactly as one big string (e.g., to have a requests-driven job take over a session you created in a browser, manually or using selenium or whatever), you can just pass that as an arbitrary header named Cookie instead of figuring out how to break it apart just so requests can (hopefully) reassemble the same header you wanted.

If, on the other hand, you need to create parts of it dynamically, then yes, you will want to do what you're doing—pull it apart to build a dict named cookie, then use it with requests.get(url, cookies=cookie), or req.cookies.update(cookie) or similar (if you're using sessions and prepared requests). Then you can easily modify the dict before sending it.

But the easiest way to do that is not to pull the cookie apart manually. I'm pretty sure the WebKit Developer Tools have a way to do that for you directly within Chrome. Or, if not, you can just copy the cookie as a string and then use the http.cookies module (called cookie in Python 2.x), like this:

cookie = http.cookies.BaseCookie(cookie_string)

Also, note that in many cases, you really don't even need to do this. If you can drive the login and navigation directly from requests instead of starting off in Chrome, it should end up with the full set of cookies it needs in each request. You may need to use a Session, but that's as hard as it gets.
