Hello all,
There's an issue with the written code that causes it to not work with the newest plotly version. It took me a couple hours to find an explanation, but it seems like the best thing is to just downgrade plotly. Here's a link to a page with a more thorough description.
https://www.reddit.com/r/learnpython/comments/10cnbrd/pcc_2nd_edition_plotly_unicodeencodeerror/
If you're using windows and the command prompt terminal, the code to downgrade plotly to the cited version is:
python -m pip install --user plotly==5.1.0
Best to you all,
Hi Eric!
I hope you and your family are well!
I tried to execute makemigrations for Entry model described on page 518 (Second Edition) and Django return an error:
TypeError: init() missing 1 required positional argument: 'on_delete'
I discoverd on Stackoverflow that since Django 2.0 the ForeignKey field requires two positional arguments and I made the modification below, after this makemigrations works fine!
topic = models.ForeignKey(Topic, on_delete=models.CASCADE)
Best Regards!

So happy that i completed PCC 2E , great journey, learned a lot, just found this error while trying to logout on chapter20, b/c we are making a get request to users/logout which is invalid one , can be solved with a form and change method to post.. happy to raise a merge request on your replay...
Code from python_repos.py:
import requests
# Make an API call and store the response.
url = 'https://api.github.com/search/repositories?=language:python&sort=stars'
# headers = {'Accept': 'application/vnd.github.v3+json'}
r = requests.get(url)
print(f"Status code: {r.status_code}")
# Store API response as a variable.
response_dict = r.json()
# Process results.
print(response_dict.keys())
Response when making the call:
Status code: 422
dict_keys(['message', 'errors', 'documentation_url'])
Any thoughts about potential fixes on this?
Hey Eric, Thanks for such an awesome and worthwhile resource. I was hoping if you could add information that the image size (in pixels) of the alien ship should be taken care of beforehand. Could be confusing for many beginners like me. Thanks again and best wishes!
In the book this is wrong when settings the DEBUG string.
note: Issue for Windows users.
heroku config:set DEBUG='FALSE'
Example:
heroku config:set DEBUG=FALSE
heroku config:set DEBUGQUOTES='FALSE'

I am receiving a ValueError when I click the "Add Entry" button after adding an entry to a topic. Below is the information that is coming back regarding the error.
I am a beginner but I believe that this has something to do with line 53 in views.py which reads:
return redirect(request, 'learning_logs:topic', topic_id='topic_id')
For some reason I don't think it likes the "topic_id=topic_id" portion of the arguments.
I have retyped everything and copied code from the repositories to ensure that I have entered everything correctly.
Any help would be appreciated.

Hi Eric,
I'm building the game with MacOS.
In ship.py
, page 242, chapter 12 is stated to:
# Update rect object from self.x. self.rect.x = self.x
self.rect.x = self.x
Although if I do write this in my codebase, I'm not able to move the ship.
I've already checked for relevant updates but the issue is not solved by using the summoned pygame version.
Thanks!

I've been working on this project for sometime following a tutorial so this is the link to the website: https://stephen-crm.herokuapp.com/ so when it comes to the user uploading his/her profile its not working can you please help me
Each new game starts as fast as the end of the last game.
Hi
I am tracking chapter 12 of Python Crash Course Ed 2 and hit an issue trying to install pygame under Python3.
Appreciate any insight into how i can get past this so I can continue with Project 1.

Hi Eric,
I came across an error when running the test_name_function.py. While I've figured it out, I feel it would be good to tell you this in case for the updating of the book. Btw, I'm a fresh learner on Python and I really like your book!
Here is the case:
import unittest
from name_function import get_formatted_name
class NameTestCase(unittest.TestCase):
"""Tests for 'name_function.py'."""
def test_first_last_name(self):
"""Do names like 'Janis Joplin' work?"""
formatted_name = get_formatted_name('janis', 'joplin')
self.assertEqual(formatted_name, 'Janis Joplin')
if __name__ == '__main__':
unittest.main()
The traceback shows that there is an error like this:
AttributeError: module 'main' has no attribute
So I googled it and I got the solution from the Medium and the StackOverflow
import unittest
from name_function import get_formatted_name
class NameTestCase(unittest.TestCase):
"""Tests for 'name_function.py'."""
def test_first_last_name(self):
"""Do names like 'Janis Joplin' work?"""
formatted_name = get_formatted_name('janis', 'joplin')
self.assertEqual(formatted_name, 'Janis Joplin')
if __name__ == '__main__':
unittest.main(argv=['first-arg-is-ignored'], exit=False)
Thank you!
While the game is displaying the Play button, the user can create a bullet by pressing the spacebar, even before clicking on the Play button.
You can reproduce this bug by cloning https://github.com/ehmatthes/pcc_2e.git, switching to the \chapter_14\scoring folder, then running the game from there.
Hi ๐
pcc_2e/chapter_13/building_alien_fleet/alien_invasion.py
Lines 102 to 109 in 078318e
I think the following line:
alien.rect.y = alien.rect.height + 2 * alien.rect.height * row_number
could be simplified into:
alien.rect.y = alien_height + 2 * alien_height * row_number
because we already have declared alien_height
variable a few lines earlier (and it's not used):
alien_width, alien_height = alien.rect.size
I'm not sure what I may be missing, I'm on page 424 on second edition and have my urls.py (both root and users), login.html, and base.html files all modified/created as in the book and this repo, but when I refresh the web page and click on the login link, I see the login button only, with no text boxes for username or password, so you cannot enter in credentials. Am I missing something here?
Python version 3.8.6
Django version 3.1.2
After completing the section 'Allowing Users to Enter Data (p410-414)', when I attempt to add a new topic using the field, I get an attribute error from the new_topic page.
'TopicForm' object has no attribute 'is_vaild'
I restarted the server but same issue. I've reviewed my code but can't find the bug. I did some research on the Django is_valid() attribute for ModelForm, but didn't see anything that would cause this issue. I'm running macOS Big Sur, terminal with bash, python v 3.7 and Django v 2.2. I'm not sure exactly which files to look at at this point, but here are the ones I'm guessing you want to look at.
I ran through all my code and couldn't find the problem. I actually started over from the beginning, when I got to this point, I had the same issue.

urlpatterns = [

path('', views.index, name='index'),
# Page that shoes all topics.
path('topics/', views.topics, name='topics'),
# Detail page for a single topic.
path('topics/<int:topic_id>/', views.topic, name='topic'),
# Page for adding a new topic
path('new_topic/', views.new_topic, name='new_topic'),
]

return render(request, 'learning_logs/topics.html', context)
def topic(request, topic_id):

topic = Topic.objects.get(id=topic_id)
entries = topic.entry_set.order_by('-date_added')
context = {'topic' : topic, 'entries': entries}
return render(request, 'learning_logs/topic.html', context)
def new_topic(request):
"""Add a new topic."""
if request.method != 'POST':
# No data submitted; create a blank form
form = TopicForm()
else:
# POST data submitted; process data.
form = TopicForm(data=request.POST)
if form.is_vaild():
form.save()
return redirect('learning_logs:topics')
# Display a blank or invalid form.
context = {'form': form}
return render(request, 'learning_logs/new_topic.html', context)

I am facing this issue in the Alien Invasion project. It is the ship.py project.
import pygame
class Ship:
def __init__(self, screen):
self.screen = screen
# load ship and get its rect
self.image = pygame.image.load('images/ship.bmp')
self.rect = self.image.get_rect()
self.screen_rect = screen.get_rect()
# start each new ship at the bottom center of the screen
self.rect.centerx = self.screen.centerx
self.rect.bottom = self.screen.bottom
def blitme(self):
# draw the ship at its current location
self.screen.blit(self.image, self.rect)
But it shows this error
AttributeError: 'pygame.Surface' object has no attribute 'centerx'
Hi,
First of all I love this book, this is my first time learning to program in any language and I'm having so much fun.
I am currently working on API's and got to the final assignment, while working on the hackernews API I ran into two issues.
The first had a pretty clear cause; while calling for the topstories and listing them I got a KeyError for 'descendants'-key. This was caused by items of the type 'job' (example), which doesn't have that key. I was able to overcome this issue by putting in a try-except statement.
For the second issue I got I was not able to find an answer so far; when the items are printed my titles are returned as tuples. The raw data doesn't have any brackets nor did I add them anywhere.
final code:
from operator import itemgetter
import requests
# Make an API call and store the response.
url = 'https://hacker-news.firebaseio.com/v0/topstories.json'
r = requests.get(url)
print(f"Status Code: {r.status_code}")
# Process information about each submission.
submission_ids = r.json()
submission_dicts = []
for submission_id in submission_ids[:10]:
# Make a separate API call for each submission.
url = f'https://hacker-news.firebaseio.com/v0/item/{submission_id}.json'
r = requests.get(url)
print(f"id: {submission_id}\tStatus Code: {r.status_code}")
response_dict = r.json()
# Build a dictionary for each article.
submission_dict = {}
submission_dict['title'] = response_dict['title'],
submission_dict['hn_link'] = f"http://news.ycombinator.com/item?id={submission_id}"
try:
submission_dict['comments'] = response_dict['descendants']
except KeyError:
submission_dict['comments'] = 0
submission_dicts.append(submission_dict)
submission_dicts = sorted(submission_dicts, key=itemgetter('comments'),
reverse=True)
for submission_dict in submission_dicts:
print(f"\nTitle: {submission_dict['title']}")
print(f"Discussion link: {submission_dict['hn_link']}")
print(f"Comments: {submission_dict['comments']}")
example output:
Title: ('How to Think for Yourself',)
Discussion link: http://news.ycombinator.com/item?id=25227651
Comments: 612
The only thing I've changed compared to the code in the book is the way the submission_dict is constructed. This was to make it more readable with the try-except statement.
Hope someone can help me clarify the cause of this issue, thanks in advance!
