Initial Code:

class A:
    def __init__(self):
        self.x = 0

    @staticmethod
    def parse(json: str) -> A:
        print('Executed')
        return A()

a = A()
a.parse('')

Problem (when run in Python):

Traceback (most recent call last):
File "c:\dev\test\python\t.py", line 1, in
class A:
File "c:\dev\test\python\t.py", line 6, in A
def parse(json: str) -> A:
NameError: name 'A' is not defined

Solution:

class A:
    pass

class A:
    def __init__(self):
        self.x = 0

    @staticmethod
    def parse(json: str) -> A:
        print('Executed')
        return A()

a = A()
a.parse('')

This solution solves the problem in Python, but create many others in PyCharm.

Still I think that it is a problem with Python - that only include a class name in available classes after parses the entire code of the class, instead of when the line with the class definition was found - I think that PyCharm would suppor it.

Problem with this solution in PyCharm:

Appear the messages in problems saying:

Redeclared 'A' defined above without usage

And sometimes:

Unresolved attribute reference 'x' for class 'A'

And there are no way to remove these messages.

It occurs because PyCharm uses the stub defined, instead of the full class defined after, to find properties and methods for the class, and, because it, PyCharm will point that method 'parse' is not defined and property 'x' is an unresolved attribute reference.

PyCharm would take the last class definition instead of the first one (the stub) as reference to find their properties and methods.

In Readme.md, in the Plugin/Code Analysis part, the DeepBugs plugin link open an Error 404 page.

Your JRE: 11.0.10+8-b1145.96 amd64 (JetBrains s.r.o.)
E:\PYCHARM\PyCharm Community Edition 2020.3.4\jbr

This repository misses the license file.
The severity of that varies from project to project, but my goal here is to attract some attention.

If it's not a problem, this issue can be closed.

I'm leaving it here just in case: https://help.github.com/articles/adding-a-license-to-a-repository/.

Thanks.

Hello jetbrain community, I am a software practitioner. I now hope that the pycharm software can add a function that I cannot name. I can only briefly explain its functional indicators. I am a pyqt developer and user myself. I often use pyqt to build some small tools that I use. But I hope that pyqt can play a role in pycharm. Just like django, pycharm can automatically create a project directory and the like. My simplest idea now is to add it to a new project, and pycharm can natively support such libraries and tool integration. Similar to qt creater. There may be some copyright issues, but I have no way of knowing, and I have no other way to gain access to the development community. I can only raise my own pull to ask questions. I think I can also support it in pycharm.

Please fix this:

I'm using the Pycharm Professional edition. I days ago, I remained file clicked on file then right clicked a mouse

>> Refactore >> Rename

Now, I can't rename files using the same way. Is there any other way to rename a file?

I usually use 1 pycharm window for one project.

I need to shut down the computer every day.

Is there any way to restore all closed windows when I continue the work the next day?

I am using window10.

Pycharm Github Tutorial ..... (2017/09/26, Chris Mahn)

It is taking a long time. Do you know how I can solve this issue?
When I updated my pycharm then I got this issue.
