Year of Programming Challenge!
Hello all, there was a post over at r/learnprogramming, it was a thread about people wanting to code everyday for this year. the community outgrew the groupme chat, and grew into a slack channel where we are sitting at 300+ members, and have 60 people forked the github repository. I thought it was a super cool idea and wanted to share it with people over here who wanted to sharpen their python programming skills!
A github organization was created where challenges can be posted and people can submit pull-requests and get their work merged with the organizations master repository. this is amazing as it will help keep our skills sharp, and start to build a github reputation thatll look good to recruiters.

Trying to make my own version of django-admin startproject. Have I created a monster?
I'm currently learning Django, specifically how to create a new project. I was taught to use the command
django-admin startproject {project name}
in bash and then modify some of the files it created. I thought that modifying the same files in the same way every time I made a new Django project was inefficient, so I wrote a shell script that would create the files for me, already modified to how they needed to be.
It seemed like a good idea at the time, but now I'm getting a whole bunch of errors I don't understand. Have I created a monster I can no longer control? Any help is appreciated.
Here is my shell script:
new_django.sh
# Activate Django Virtual Envirnoment
source ~/Desktop/PYTHON/myEnvironments/djangoEnv/bin/activate
# Get names of project and app
echo "Enter project name:"
read project_name
echo "Enter application name:"

Major issue with templates, not updating
I have no idea how this happened, but whenever I update my templates/views/etc it updates as expected. However if you keep refreshing any page on the site it shows an old template randomly. Say if you refresh the site 6 times half the times it will show an old template. If you go to a new page and keep refreshing it, it will 404 as if it doesn't exist.
It's almost like there are two instances going on - if you keep refreshing it goes back and forth.

[AF] Storing class object across requests?
Hi all, I'm learning Flask by attempting to build a Blackjack game.
Currently, I have a few views defined as well some of the game logic in a file/module called `game.py`.
What I'm currently doing:
The user visits the `trygame.html` page where the game can be played without the user having to register/sign in. For the future, I intend to create a full fledged game that includes leaderboards and game setting options.
What I am having issues with:
Right now, I am simply attempting to deal a new card from a `Shoe` (representing a dealer's shoe) object. This works. HOWEVER: Everytime I hit "Deal card" the object appears to reinitialize itself. Obviously, I want to avoid this until the `Shoe` is empty.
An excerpt of my `game.py` file:
class Blackjack(object):
def __init__(self):
pass
NO_OF_DECKS = 1
SUITS = ['clubs', 'spades', 'diamonds', 'hearts']
RANKS = ['A', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K']
VALUES = {'A': 1, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8,
'9': 9, '10': 10, 'J': 10, 'Q': 10, 'K': 10}
class Shoe(Blackjack):
""" Creates a new shoe object from which cards are dealt
to the player and the dealer.
Input arguments:
decks :: the number of decks the player wishes to play with.
"""
def __init__(self, decks=1):
self.cards_in_shoe = {}
self.total_cards = decks * 52
for i in Blackjack.SUITS:
self.cards_in_shoe[i] = Blackjack.RANKS * decks
def get_random_card(self):
random_suit = random.choice(self.cards_in_shoe.keys())
cards_in_suit = self.cards_in_shoe[random_suit]
random_card = random.choice(cards_in_suit)
cards_in_suit.remove(random_card)
# deleting suit if cards exhausted.
if len(self.cards_in_shoe[random_suit]) == 0:
del self.cards_in_shoe[random_suit]
return (random_suit, random_card)
def remaining_cards_in_shoe(self):
""" Returns the total number of cards remaining to be
drawn for both player and dealer.
"""
return sum(len(v) for v in self.cards_in_shoe.itervalues())
Using the terminal/command line, everything works.
Here is my current `trygame` view: (not working)
@app.route('/trygame', methods=['GET', 'POST'])
def trygame():
shoe = game.Shoe()
card = shoe.get_random_card()
remaining_cards = shoe.remaining_cards_in_shoe()
return render_template('trygame.html',
card=card,
remaining_cards=remaining_cards)
Now, I understand that every time we render the page, we initialize a new `Shoe` object, which is obviously incorrect.
So now I'm thinking what is the proper way of dealing with this. Is it current_app? Is it session? Is it something else?
I'm strongly tending towards session, so I'm thinking something like this:
@app.route('/trygame', methods=['GET', 'POST'])
def trygame():
# I believe this is the way to go, but it won't work
print session
if request.method == 'POST':
card = session['shoe'].get_random_card()
remaining_cards= session['shoe'].remaining_cards_in_shoe()
return render_template('trygame.html',
card=card,
remaining_cards=remaining_cards)
session['shoe'] = game.Shoe()
card = session['shoe'].get_random_card()
remaining_cards = session['shoe'].remaining_cards_in_shoe()
return render_template('trygame.html',
card=card,
remaining_cards=remaining_cards)
Unfortunately however, I am unable to store the object in the session variable, as it's not JSON encodable. And if I

force it to JSON, then I obviously cannot call methods on it, as they don't exist.
Long story short, how do I get this to work correctly? Also, if session is the way to go here, how do I keep the user from seeing the content of available cards in shoe, as well as the dealers hand value (something I will have to deal with in the future..)
Thank you so much in advance.

[AF] Is it possible to display data from a list and provide a download link?
I have created a Flask app that creates a list and returns the list to an HTML page. I would also like to make the list downloadable as a CSV file.
So far I understand how to do these tasks as separate functions.
Is there a way to combine these functions into one so that a list is created only once, displaying the data on an HTML template, and also providing a download link?
Please view the basic examples below:

Django app store/repository (django newbie)
I did a `pip search django` which returned >4000 modules, which is kinda useless for me. As a newbie I'm stuck with 2 issues:
* Browsing for applications -> Does Django have something akin to Docker's http://store.docker.com? A related question: Which 3rd party Django apps should an aspiring developer be aware of?
* Integration -> Any supporting tooling for this? Or is it "just" a matter of `git clone AppX` and manually editing config files?

Django+React
I'm a beginner-intermediate web developer.
As a personal project, I want to create a todo app for an imaginary company with the following features:
1. user can create, edit or delete a task (similar to the one shown in https://www.youtube.com/watch?v=IR6smI_YJDE&t=1791s)
2. each task can be marked "unstarted", "in progress" or "completed"
3. tasks can be sorted/filtered chronologically or in terms of their progress
4. users have to login to the system. There are 2 access levels: the employers can only view the tasks, whereas the boss can view and edit the tasks
I figured the frontend of 1-2 can be done with React, whereas the backend of 1-2, as well as 4 can be done with Django. (3 can be done with only JavaScript I guess) I have been learning bits and pieces of web development on my own, and I have no idea if this is the best practice? Is there another way to implement the features? Is it worth the effort integrating Django with React?
