talkpython / mastering-pycharm-course Goto Github PK

I'm as confident as I can be that I followed the instructions here word-for-word, but I just could not get any autocomplete/intellisense functionality going on in the last step where it's supposed to happen in the .py file.

I've got the virtual env set up with requirements installed. That virtual env is the project interpreter. I've got the data source added. I've typed (not pasted) the string in...nothing

I regard this as low priority

I have downloaded the 4-refactoring for Your turn: Refactoring.
I am getting following when I run it.

Welcome to the talk python info downloader.

Working with total of 25 episodes

Process finished with exit code 1

The Python version I have in the virtual environment is 3.8.2 and I have version 2020.1.1 Professional Edition on an iMac with macOS Catalina.

When I try to do the first part of the Large module smell exercise I get the following error:

The steps I'm trying to do is:

• Select the following two lines

Episode = namedtuple('Episode', 'title link pubdate show_id')
episode_data = {}

• Right-click
• Select 'Refactor / Move'
• Change the filename to service.py
• Click 'Refactor'

I'm not sure if I'm doing it the wrong way or if it might have something do do with my OS and/or version of PyCharm.

I'm running version 2018.2 on Xubuntu 16.04.

This isn't necessarily a mistake in your book, but PyCharm currently has a bug that isn't getting a lot of attention. the bug prevents anyone from following through the chapter as written. JetBrains is aware of it, here's the following post I found regarding it that provides a link to their YouTrack page of the bug https://intellij-support.jetbrains.com/hc/en-us/community/posts/360005076019-PyCharm-Pyramid-Project-with-Chameleon-Templates-Selected

Hopefully you can provide a work around for the time being?

Error in LIST
Please do help

The instruction below is not working, as you can see on the attached image.

"Notice that wake_up should have some warning about it not existing. Put your cursor on wake_up, press alt-enter, and choose "Add method wake_up to Wizard class"."

Now that PyCharm has more direct support for Jupyter, consider adding a short section on this directly.

It's a minor issue. But since I have both courses in my bundle, and that "Mastering" has been superseded by "Effective", it makes one wonder if the the sources were updated but not appropriately linked in the "Effective PyCharm" page

List all the tool windows mentioned in chapter 12 and sorted them
based on the order they appear.

Is PyCharm Professional Edition required for the data science "Your Turn: lab? If so, you might want to list that at the top of the "Your Turn" lab. Thanks!

The course may have mentioned this prerequisite, but I think PyCharm Professional Edition is required for the Data Science Lab. I spent some time trying to figure out how to turn on Data Science Mode, and couldn't find it in the new project wizard.

Then I stumbled upon this:
https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000682290-PyCharm-EAP-where-s-the-scientific-mode-

and this:
https://www.jetbrains.com/pycharm/features/editions_comparison_matrix.html

I could be wrong, but it looks like you need Professional Edition for this lab.

Thanks,
Andrew

Class Wizard in 2-the editor folder is missing an the .attack() function. This is causing an unresolved reference in the program.py file (note, this was probably a miss, but could be added to instructions on how to resolve)

We want the app version in the header!

Hello, hope everyone is doing well,
I'm new to python and I'm coding out my project but can't get the widgets to match each other vertically, I've used columnspan but still, any help?

Not sure if it's just me, but after reformatting and removing imports the hero.attack ended up on line 58 of instead of the line 57 stated on lines 44 and 48 of the bad_wizard readme. ;)
I'm using pycharm pro 2018.1.3 and running Linux Mint 18.3

I have been struggling with the ModuleNotFoundError: No module named 'requests' error for a while now. I am running Python 3.8 on a Windows 10 platform. I downloaded the python-jumpstart-course-demos files using the GitHub Desktop app. This error is affecting everything I am attempting to do with Python in PyCharm. I believe that it may be a path issue. Usually when I import a library this error appears.

In the instructions views.py is mentioned. With the current version of tooling and framework it seems default.py is the place this should be added. at least that works.

Just a quick comment re the Cython extensions under Linux in Part 7.

I'm currently running 2018.2 and at least from that version you no longer need to manually cut-paste the instructions for how to install the Cython extensions for debugging.

There's the normal 'install something' link being displayed and you just click that and PyCharm sorts it all for you.

Nothing major, just a minor change in behaviour that may or may not be useful to add if you update the content at some stage in the future.

Cheers, Mike

In your-turn | 05-databases | readme should line 32 be changed from

There should be 5 tracks that match.

to

There should be 4 tracks that match.?

We actually don't use pandas. https://github.com/talkpython/mastering-pycharm-course/blob/master/your-turn/11-scientific-computing/readme.md#use-pycharms-data-science-mode

Hi Mike,

service.py is empty. I guess it's an accident?
mastering-pycharm-course/your-turn/4-refactoring/smelly_podcast/service.py

@mikeckennedy , There's a discrepancy between the instructions and the behavior of PyCharm.
The README has an example using Google style docstrings:
https://github.com/talkpython/mastering-pycharm-course/blame/main/your-turn/02-the-editor/readme.md#L63

but Pycharm uses regular style by default. Some students may find this confusing.

My copy of PyCharm (Professional 2020.02 on macOS Catalina) does not see the virtual environment on first opening a project. I am running Python version 3.8.5, installed in /usr/local/bin by HomeBrew.

I followed the instructions under Your Turn - Configure a complex project.
Step 01 shows the Project in PyCharm
Step 02 shows when I run the program PyCharm uses /usr/local/bin/python3.8
Step 03 shows the project interpreter screen

So, you may want to add to the video a section on what to do if the virtual environment is not the default interpreter:
Step 04 - click the gear icon and choose Add...
Step 05 - the Existing environment choice should show the virtual environment already filled in. Select Existing environment and click OK
Step 06 - running the program now uses the correct Python from the virtual environment

I'm a Python noob so I may just be confused, but the latest podcast resulting from expected_final_version is 1 less than the latest podcast resulting from the smelly_podcast. I don't think was intended. You can fix this by adding "+1" at the end of line 19 on the program.py file under expected_final_version. Not sure this is the sexy Python way of fixing it.

Also, when I follow the instructions:

Next up, we have "GET LATEST SHOW ID". We want a method that will return that value. So highlight just max(episode_data.keys()) in the line:

latest_show_id = max(episode_data.keys())

Choose extract method again. Notice that this time, PyCharm found another usage (duplicate code!) we can replace that with this method call too (automatically).

Refactoring to Method doesn't find another usage for duplicate code.

For the instructions:

Finally, notice the remaining section label "DISPLAY RESULTS".

Highlight that and extract it to display_results().

Rerun your program (again, and again). It's still working right? OK then, carry on.

I end up with a display_results() method with "latest_show_id" and "oldest_show_id" as parameters.

The comment for this issue. Just for a screenshot in the book.

I tried to duplicate the code of the podcast example and run it, and got no output.
When I looked into it I saw that ElementTree.fromstring did not work well, and the items that findall created were all empty.

It mentions:
sys.path.extend(['/Users/mkennedy/Desktop/pak'])

Perhaps should mention users directory where he/she should point to...

This line: "Create a folder next to views.py called fake_data.py. Copy this method into that file:" (emphasis added) would probably me more accurate if it said:

"Create a file next to views.py"

In the file searcher app, users have run into this error:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position 304: invalid start byte

The problem here is there is a binary file that is being fed to the read text file option (open(file, 'r')). Here is the fix:

def search_file(filename, search_text):
    
    # NOTE: We haven't discussed error handling yet, but we
    # cover it shortly. However, some folks have been running
    # into errors where this is passed a binary file and crashes.
    # This try/except block catches the error and returns no matches.
    try:

        # matches = []
        with open(filename, 'r', encoding='utf-8') as fin:

            line_num = 0
            for line in fin:
                line_num += 1
                if line.lower().find(search_text) >= 0:
                    m = SearchResult(line=line_num, file=filename, text=line)
                    # matches.append(m)
                    yield m

            # return matches
    except UnicodeDecodeError:
        print("NOTICE: Binary file {} skipped.".format(filename))
