Course Summary

#100DaysOfCode in Python is your perfect companion to take the 100 days of code challenge and be successful. This course is 1-part video lesson, 2-parts guided projects. You will be amazed at how many Python technologies and libraries you learn on this journey. Join the course and get started.

What's this course about and how is it different?

100 days of code is not just about the commitment. The true power and effectiveness is in having a guide and pursuing the "right-sized" projects. That’s why we have 33 deeply practical projects. Each paired with 20-40 minute lessons at the beginning of the project.

Just a small sampling of the projects you’ll work on include:

• Understanding basic Python data structures
• Searching large text corpuses with regular expressions
• Consume HTTP services including the Twitter and GitHub APIs among others
• Visual data with graphs using plotly
• Convert your Python CLI (command line interface) app to a GUI application
• Program against Excel in Python to automate your spreadsheet data
• Build a text-based game and learn object-oriented programming
• Automate multi-step web processes using selenium
• Test your code with pytest and unit testing
• Create a basic web app with Flask
• Create a JSON-based online game service using Flask too
• And 22 more projects!

View the full course outline.

Who is this course for?

This course is for anyone who wants to immerse themselves in Python for 100 days worth of learning and hands-on projects.

We don’t start from absolute zero in terms of programming but if you are new to Python we have a language appendix and we start somewhat slow. By the end of the course, we get into intermediate-level Python projects.

Course flow and the 33 projects

We have broken the 100 days worth of coding into 33 3-day segments. As you can see, the first day is largely learning the new topics (HTTP APIs, web scraping, databases, etc.). The following two days have some guidance but is much more hands-on than the first day.

100daysofcode-with-python-course's Issues

urlretrieve function

This function can't use anymore since is removed from python.

How can I handle this problem? Are there any function can be replaced with this function?

** Days 4-6

Missing file 94-96days

On the readme there is a link to the build.spec (line 61). The link in broken file not found.

Consider rewording

The first sentence on the following page is hard to read, it tripped me up and I caught myself re-reading it.

https://github.com/talkpython/100daysofcode-with-python-course/blob/master/days/25-27-error-handling/README.md

One of the key differentiators of professional programs and scripts thrown together by beginners is pro app does not crash.

Perhaps it could be re-written like one of the following:

One of the key differentiators of professional programs and scripts thrown together by beginners is that the pro app does not crash.

Missing README for days 04-06

G'day Michael and team,

There is no README file for days 04-06. I managed to navigate to the exercise eventually from the link in the video, but was under the impression that all days would have README instructions.

Cheers,

Conor

Day 55-57 Example - write_post()

Within my write_post() implementation, the call resp.json() in the print() returns a list of the previous (in my case) three published items but not the new post that the write_post() was to create. I ran this the original project code using both uplink version 0.4.0 and uplink version 0.9.1 with the same results. I have double checked the source code with the code posted in github. The console output is provided below. Any assistance is appreciated.

packtpub 'find_element_by_name' doesn't work

Hello, the find_element_by_name as described in the tutorial does not work for this site. Additionally it looks like they've updated their website and don't have the ebook page that is used in the walkthrough. Could this be updated/looked into?

Link for the pytest fixtures article (day 12) is broken

The link to the pytest fixture article in the day 12 section is broken.

It points to https://pybit.es/pytest-fixtures.html, whereas it should point to (thanks Google!) https://pybit.es/articles/pytest-fixtures/.

isn't there a group you created

for the members of "100 days challenge" ?
you know , special group we could share , get advice etc. and not in my twitter ?

The sample json data file in day 40-42 is not in json format

Hi Guys
I was trying to load the 100daysofcode-with-python-course/days/40-42-json-data/code/mount-data.txt using json.load() module and I'm getting the error 'json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes:'.
As per stackoverflow article https://stackoverflow.com/questions/39491420/python-jsonexpecting-property-name-enclosed-in-double-quotes, the format is not correct. Can you confirm pls?

Add section about setting things up

It would be good for any beginner to have lesson about setting a enviromment virtualenv and other things. If this would be good for you, I will be happy to do that.

Day 55-57 results in Type Error for __init__

Hi.

When I execute program.py for the Day 55-57 example I run into the following Type Error:

I tried multiple angles I am familiar with but nothing has worked so far.

Day9: working with dictionaries

Hey there,

Having a hard time following instructions for day 9. Dictionaries are unsorted. So printing out the nth dictionary entry doesn't make sense to me. Since the dictionary is in alphabetical order in data.py, I assumed this means that is the "order" the instructions are referring to. So I generated a new dictionary with the index as the key.

However, the last instruction says to replace the key in the nth position of the dictionary with the value from the nth position in the list. However, that would create a duplicate key in the dictionary and doesn't work.

Please let me know if I'm completely missing something here!

Thanks very much!

Small detail on capturing all capitalized words

In your code you use the regex
r'[A-Z][a-z0-9]+'
as the pattern, but that would not count capitalized one letter words (i.e., I or A), capitalized words with apostrophes (e.g., Don't, Isn't, O'Leary) and it would also miss words (or abbreviations that had one or more capitals (e.g., USA, STOP and McKnight). There are certainly much more complicated ways to write the pattern, but I would suggest the pattern
r'[A-Z][A-Za-z0-9']*'
It is not a big deal, but I thought I would mention it. This might capture unintended strings (e.g., lists with letter counters like '(A)', '(B)', etc.; variables that show up in equations like X + Y; non-word strings like UK postal codes - EC1, W8, etc.), but I am of the school of thought that I would rather have more data than less.

day 2 error

Hello,

I am trying to figure out what went wrong with my code for the day 2 challenge. I am pretty sure the result is correct.
Which for challenge one is 2017. 07.08 and 505 days for challenge 2.

Challenge :

1. We kicked off our 100 Days of Code project on March 30th, 2017. Calculate what date we finished the full 100 days!
2. PyBites was founded on the 19th of December 2016. We're attending our first PyCon together on May 8th, 2018. Can you calculate how many days from PyBites' inception to our first PyCon meet up?

My code :

from datetime import date, timedelta

start_100days = date(2017, 3, 30)
pybites_founded = date(2016, 12, 19)
pycon_date = date(2018, 5, 8)

def get_hundred_days_end_date():
"""Return a string of yyyy-mm-dd"""
end_date=timedelta(days=100)
finish_day = start_100days + end_date

print(str(finish_day))

def get_days_between_pb_start_first_joint_pycon():
"""Return the int number of days"""
in_between_days = pycon_date - pybites_founded
print(str(in_between_days))

get_hundred_days_end_date()
get_days_between_pb_start_first_joint_pycon()

error return :

Itertools traffic light task

Hi, I think there's some missing info in the itertools unit readme. It says to try to complete the task before watching the video, but the only description of the task in the readme is "create a script that simulates traffic lights" - it's not obvious what it is.

Link in day 5 is broken

Hi, started the course a few days ago and I noticed that the link to PyBite 13 that appears in day 5 is broken. I get a 404 error.

Also, I think that the url given in the notebook to retrieve the data is not valid anymore.

Thanks Michael for all that you put out there for people to level up in Python 🙏
I'm a big fan of TalkPythonToMe

Pyperclip does not work correctly under Linux

I had issues with pyperclip. Copying text to the clipboard did not work. Found the solution for my problem on the pypi page of pyperclip:

"... On Linux, this module makes use of the xclip or xsel commands, which should come with the os. Otherwise run “sudo apt-get install xclip” or “sudo apt-get install xsel” (Note: xsel does not always seem to work.)

Otherwise on Linux, you will need the gtk or PyQt4 modules installed."

Everything works fine now, after I have installed xclip.

Day38 - bad data in csv file

Hello,

On Day 38 when loading the Thanksgiving data from the file, there is a error that occurs:

UnicodeDecodeError:

'utf-8' codec can't decode byte 0xed in position 3599: invalid continuation byte

The file gets processed until the record with 'RespondentID':'4335955206' then it errors out.

Also when opening the csv file in PyCharm I get "File was loaded in the wrong encoding: 'UTF-8'"

The error goes away when removing the line with RspondentID: '4335955152'

Packt Publishing website updated

Hi,

the website packtpub.com has been updated, the code in the notebook does not work any more. I found the field for the user name in the code inspector but was not able to find the right element qualifier to address it. The 2nd example with the pybites banner generator did of course not work either because Bob did not reveal his password. Can't you find (or create) a website that is not changed frequently and easily accessible for everyone?

Cheers,
Andreas

The subtitles for the deque and first concept videos (days 4-6) are swapped around.

I followed the collections chapter tonight and found that the subtitles for the deque and first concept videos (days 4-6) are swapped around. I.e. the concept subtitles were shown during the deque video and vice-versa. (BTW - this is my first ever issue raised on GitHub so I hope I've done this right!).

Days 58-60 Twitter

Might need to update the md or video for this set of days.

apps.twitter.com is being sunsetted and moved to https://developer.twitter.com/en/apps

There is also an approval process (maybe there always was, but there is one now)

day 04-06 encoding problem on file open

There are some extended ascii characters in the csv download. It seems jupyter doesn't mind, but if you're doing this on IDLE or some other thing with CPython, it balks on reading the file, starting at character 535. This can be avoided by adding """encoding='utf-8'""" to the open statement.

Possible misleading typo in 22-24 Decorators

In 100daysofcode-with-python-course/days/22-24-decorators/decorators.ipynb under "Second day: a practical exercise" you list the following block of code:

@make_html('p')
@make_html('strong')
def get_text(text):
    pass

As the problem is listed now it implies that make_html decorator should be responsible for printing the test instead of just adding tags. In the linked pybite get_text() is defined as:

def get_text(text):
    print(text)

Is that pass in the jupyter notebook a typo, which instead should be print(text)?

Day05 exercise - SSL: CERTIFICATE_VERIFY_FAILED

100 Days of Code

video 'hello test world'

This video was very disappointing . Your explanation of the command line arguments was extremely superficial. I cannot get it to work. I am starting to regret buying this course. can you point to a better, more detailed explanation of how to run pytest. Thanks.

Issue in the #100DaysOfCode talkpython course Days 28-30 regex

Hi guys
In the recording for 'findall' section, Bob mentions in one of the exercises, '\w+' as one or more characters. Shouldn't that be one or more 'words'?
