This is a silly scraper program I wrote while I was learning Python. It is meant to work on a rpi zero w and pulls data from a very simple website using tabular data. It pulls the current score of my favorite NFL team. If the Bills are winning, it will illuminate a green led, if they're losing a red led and if the score is tied, both lights will be activated. It provides an easy visual to check the status. It should be pretty easy to manipulate the code to your favorite team and GPIO pins of your choosing.

if u can find a more efficient way to put forward these questions since with the model i was using there were some problems with acceping string data so every question is yes or no. The model i used was working but the code is 120 lines due to the unacceptance of string data. 

[Smyan Narang]

also i know that i hv done int input so string input wont work but i tried normal string input earlier and that didnt work so...

i did something similar. I basically created a code to take the highest rates movies from imdb and go into one of my tv channels providers websites and if any of the movies were coming in the database it would print the date and time to tell when the movie will be showing(this was a time when my ott subscriptions were cut so i had to rely on live TV channels)

If that's Python  maybe you should use tkinter or something to make a GUI and use  input boxes, checkboxes and selection lists 

Then store all your questions in a csv file, or a json file or whatever for example 

 

variable name ,  input type  (checkbox for yes/no, true/false , input ) , question text ,  answers , min , max 

 

input type :   'c' = checkbox yes/no  , 't' = text input , 'n' = number input , 'o' = option list / selection list

answers  = for selection list  , enter possible answers  separated by some special character, for example '|'  ex  "Please choose:|Female|Male|I'd rather not say"  and 0 is please choose / nothing selected , 1 is female , 2 is male , 3 is I'd rather not say 

min and max  - minimums  and maximum values allowed  ex for age, say min=1 , max = 100 and report error if number is outside range.  Or min = 1 max = 3 for the selection list above will force user to actually pick something and not leave the selection on the default "Please choose:"

 

So your first few entries above would be something like : 

 

"age" , "n" , "Student age:", "",1,100

"fedu", "c", "Mother is educated","",0,0

"medu" , "c", "Father is educated","",0,0

"traveltime" , "n", "Number of days in a year your ward travels (1..366):","",1,366

"studytime", "n", "Number of hours in a day your ward studies (1..24):", "",1,24

"fjob", "o", "Mother's workplace" , "Please choose:|Healthcare|Financial services|Education (Teacher)|Other", 1,4

"fjob_other", "t", "If Other, please enter mother's job description:", "",0,0

 

Makes it much much easier to add or remove questions, no going in code to add stuff ...  edit questions, correct limits, validate input to some degree, allow user to go back and correct instead of getting bad data... 

 

... so your program can read the csv file line by line and put them in an array and  automatically create the controls (checkbox, selection list etc) on the screen and make some basic validation. Then your program can also use the array to retrieve all the information and dump it to a file in some format you can handle (csv, json, binary dump etc)

Would be super easy to do in PHP or Javascript, to have a FORM tag and populate the form with checkboxes and text inputs and number inputs and selection lists and then when the form is submitted or a button is pressed , the php code or javascript can collect the data and save it as required.

i did use tkinter and made a gui and all the questions were stored in a csv file in the final project but this is the root of the project and wanted to make this part right

I'm very new to web scraping and am finding it's really difficult to understand the layout of web sites and knowing how to consistently pull the correct data when a website updates. I've tinkered with python for about a year and would consider myself to be a beginner-intermediate. Mainly, I'm trying to find useful projects for my rpi's

Take a look at css selectors.

Development tools in browsers (F12 or right click -> inspect) can help a lot to find the data you are looking for. Under the console tab there is a fancy live javascript console where you can type code. For example typing in $$("#content .game_summary") will find all elements with the game_summary class inside the #content div.

 

The same thing using BeautifulSoup would look like this: soup.select('#content .game_summary')

I hope this helps

Something that always drives me nuts is when I'm using an interface, and go to click on some part of the menu, but I do it at roughly the same time the program decides to make some change to the interface, and so I end up clicking on some button, option, etc.  It's always irritating, and depending on what the new item I can click on is, the results can be disastrous.

What I've started doing on the sites I work on is to "pause" certain events when I make changes to the interface for a few hundred milliseconds, to give the user time to recognize that the interface has changed.

The way I accomplish this is to attach an event listener to the document itself during the capturing phase (i.e. where the very first event listeners are called) and have it stop propagation and stop default.  I then use setTimeout to remove the handler after a certain period of time.

 

	function disableEvent(event, time){
	  var h = function(e){
	      e.preventDefault();
	      e.stopPropagation();
	      return false;
	  }
	  var ref = document;
	  ref.addEventListener(event, h, true);

	  setTimeout(function(){
	      ref.removeEventListener(event, h, true);
	  }, time);
	}
    
    //Example using it.  Disable the click event for 800ms
    disableEvent('click', 800);
    

Technically it doesn't fully prevent any action from taking place;  if another event listener was added to the document before this one, which also used capturing, then it could still get executed, however this is extremely unlikely since a) most people don't attach event listeners to the document itself, and b) most people don't event listeners with capturing.

not pretty, but appears to be working. You enter how much filesize you can download per second and how a big a file you are download is and you get an estimate for download time. The prefix of the unit (G, M, etc.) is always in capital and the B (B/b) indicates wether your unit is in bytes or bits.

Initially i wanted to clean up the code after completing, to get back under 100 lines, but i managed to do so without it (good job, i guess?? should have cleaned the code anyway probably). Hope i made no mistake in the unit conversions.

This script creates a Firefox headless browser that will tune into a PeerTube live stream if one is available. By default it checks https://jupiter.tube/ (the peertube instance of the guys at Jupiter Broadcasting). This script is not useful for everyone, but it will help the swarm effect that is really needed for a PeerTube stream.

At the time of this post, it is only 63 lines.

P.S. The repo has instructions to run in docker if anyone is interesting in this little script

Can someone give me an intermediate Python challenge to do?

[undergroundbeef]

I wanted to make something for those times where I have a list of stuff I need to do something with, and I need to keep track of where I am in the list, while also copying the item in the list to use it. This seemed like something I needed a lot in the past, but never actually used it once I made it (probably due to changing job roles).

 

A list of stuff can be entered in the big box (one item per line), click the button and you get the list to work from. Click a row and it will copy it to your clipboard and cross the item off the list. Click something again and it will uncross it off, to show it still needs to be done, but won't copy it again. I have some memory when writing this of it not working in certain situations (when hosted maybe... but I just tried it with a local file, no server, in Safari and Firefox, as well as hosted on a web server and it all seems to work, so maybe I fixed it and forgot). The reload arrow in the upper right takes you back to the input screen.

 

I had to make the braces kind of ugly for the 100 line limit, but it's 100 exactly.

This is a little website I made because my microwave is only 800 watts and most packaged food is tested at 1000 or 1100. This lets me pick the wattage of the directions vs the wattage of my microwave, set the time from the directions, and it tells me how long to cook it. I use this constantly. 94 lines.
