python Why doesn’t list have safe “get” method like dictionary?

Is it possible to pass parameters with an HTTP get request? I have found an HTTP post requst (link). In that example the string postData is sent to a webserver. I would like to do the same using get instead. Google found this example pos systems tutorial on HTTP get here. However no parameters are sent to the web server.

• Probably because it just didn’t make much sense for list semantics.
• In a GET request, you pass parameters as part of the query string.
• Now foo and bar are either the 4th and 5th values in the list, or None if there weren’t that many values.

• It makes sense to ask if an entry exists or not.
• If you just wanted to use this with lists created by your own code you could simply subclass list and add the get method.

• Because lists are forward packed the only fail case we need to worry about is running off the end of the list.
• However no parameters are sent to the web server.

In that case you typically also create them before hand filling them up with None or 0, so that in fact any index you will use already exists. Now foo and bar are either the 4th and 5th values in the list, or None if there weren’t that many values. It makes sense to ask if an entry exists or not. It isn’t common to ask if L10 exists but rather if the length of L is 11. Instead of using .get, using like this should be ok for lists.

How to make an HTTP get request with parameters

In a GET request, you pass parameters as part of the query string. If you just wanted to use this with lists created by your own code you could simply subclass list and add the get method. To use this function you just need to create two NameValueCollections holding your parameters and request headers.

Because lists are forward packed the only fail case we need to worry about is running off the end of the list. This approach pads the end of the list with enough defaults to guarantee that index is covered. Probably because it just didn’t make much sense for list semantics. However, you can easily create your own by subclassing. Your usecase is basically only relevant for when doing arrays and matrixes of a fixed length, so that you know how long they are before hand.
