How to solve list complex issue in python?
Have the function testfunction(num) take the num parameter being passed and perform the following steps. First take all the single digits of the input number (which will always be a positive integer greater than 1) and add each of them into a list. Then take the input number and multiply it by any one of its own integers, then take this new number and append each of the digits onto the original list. Continue this process until an adjacent pair of the same number appears in the list. Your program should return the least number of multiplications it took to find an adjacent pair of duplicate numbers. For example: if num is 134 then first append each of the integers into a list: [1, 3, 4]. Now if we take 134 and multiply it by 3 (which is one of its own integers), we get 402. Now if we append each of these new integers to the list, we get: [1, 3, 4, 4, 0, 2]. We found an adjacent pair of duplicate numbers, namely 4 and 4. So for this input your program should return 1 because it only took 1 multiplication to find this pair. Another example: if … -

Cannot import ThreadSensitiveContext from asgiref.sync, Upgrading django to 4.0

how do I consume django api from react frontend
I'm new to React, I've written a Django API endpoint to perform some kind of sync. I want this API to be called from a React page, on clicking a TextLink - say Sync Now, how I should go about doing it? Based on the response from the API(200 or 400/500), I want to display Sync failed, on successful sync, I want to show Sync Now again, but with another text Last Sync Time: DateTime(for this I've added a key in my Django model), how can I use this as well. Also, I've a followup, say instead of Sync Now and Synced we have another state Syncing, which is there until a success or failure is returned, Is polling from the server is a good option, or is there any other way. I know of websockets but not sure which can be used efficiently. I've been stuck here from 3 days with no real progress. Anything will help. Thanks in advance. -

How to protect your API from abuse - DRF & React
I'm really struggling to wrap my head around the concept of protecting ones API end point. How do you do you protect it from abuse if it's exposed with React? I understand if a user were to login then be issued them with a token etc. I get that. But let's say have a front end that does not require someone to be logged in? They simply filling out a form with their details and it gets passed via you API then gets stored in the DB. Whats stopping someone just abusing your API? They could just write a script and attack you end point with spammy data? I just can't understand how this is protected? -

Django - Return a list of months that a query of Post objects spans to front-end in local time
So I have kind of a weird and interesting problem. Lets say I want to be able to group posts on an application like Facebook by months in local time to whoever sent the request. Let's say I have a Post table in Django with the standard created, body and author fields. Where created is the date and time it is created. Let's say I want to find all posts by a user so that query would look like Post.objects.filter(author=<some name>). I want to be able to send back to the requester for these posts the dates they span. The reason this is slightly tricky is because Django stores in UTC and has no notion of user's time zone unless given. My initial idea would be make a url that's something like /post/<str:author>/<str:timezone> then somehow convert created date for all queried Post to that time zone and figure out the months. The timezone is needed to cover the edge case that someone posts on the last day of the month. Depending on the time zone that could be the current month in UTC or the next. How would I find all the months in the requestors timezone that Post span … -
