Problem Description

When i’m using Pylance as Python Language Server it won’t show me references for use of the methods.

I’m passing the TestClass1 Object to the TestClass2 Object.

If i’m going to the classes1.py file and hit ‘Find all References’ i am just getting the reference inside that file (which is the definition of the method).

Faulty references to the method in classes1.py

src/folder1/classes1.py:

class TestClass1():
    def __init__(self, word):
        self.word = word
        
    def print(self):
        print(f"Word: {self.word}")

src/folder2/classes2.py:

class TestClass2:
    def __init__(self, printer):
        self.printer = printer

    def testprint(self):
        self.printer.print()
        

main.py:

from src.folder2.classes2 import TestClass2

printer = TestClass1("Hello World")
def main():
    test = TestClass2(printer)
    test.testprint()

if __name__ == "__main__":
    main()

All filepaths are relative to the project folder.

When i’m switching to Jedi Language Server it works perfectly fine. But Jedi on the other hand is not really usable because i get an bug when trying to rename symbols. In every file that it refactored the code to the new symbol name it just adds new lines in between the code.

Expected Result from Pylance

I played with some settings but whichever setting i manipulate, nothing has worked.

{
    "python.languageServer": "Pylance",
    "python.analysis.autoImportCompletions": true,
    "python.analysis.typeCheckingMode": "basic"
}
