File reading issue in Python

Solved
Erwan2212 -  
Hello everyone,

I coded an application in Python a few days ago, and I have a problem that seems silly but I can't solve it and I'm coming to you for help. The issue is that Python cannot find the file named 'Licence.txt'; the strangest thing is that it is in the same directory, and I don't know why.

Here is my code: 

self.textLicence.setVisible(False)
 self.text = open("Licence.txt","r")
 self.text.read()
 self.textLicence.setPlainText(self.text)

and here is the error message: 
File "/home/erwan/Desktop/Projet/Class/appr_main.py", line 17, in traitement
 self.text = open("Licence.txt","r")
FileNotFoundError: [Errno 2] No such file or directory: '/Licence.txt'


If anyone has an idea, it would be greatly appreciated.
Thank you in advance.

    The ideal when asking a question is to immediately indicate which operating system

    we are on and which version of Python ...

      Ah OK you are on Linux, you should have said that right away

      I am on Windows ....

        Yes, I've done everything, but it only brings me failures. I'm on Lubuntu 20.04. Don't you have any other idea?

          Whoa!

          Try using the actual full path:

          C:\\Users\\erwan\\Desktop\\Project\\Class\\Licence.txt

          if Erwan is indeed your username on your computer.

          For me, it looks like this:

            Yes, everything is normal, but I don't know why Python can't find my file.
            I tried like this but still nothing 
            self.text = open("~/Desktop/Project/Class/Licence.txt","r")

              And your file is named Licence.txt with a capital L?

              And is it in the same directory as appr_main.py?

              And what if you used the full path to see:

              self.text = open("C:\\Phil\\Licence.txt","r")
              1. Erwan2212 Author
                Yes, that's all there is,
                it's the code just above in appr_main.py
                I'm lost Phil, I can't solve it up to now.

                  I don't know ...

                  What I mean is that your program is not just the definition of a class,

                  but there's more to it than that, right?

                  The program has to start somewhere; you must create an object from the class and then use it ...

                  What's in appr_main.py?

                    Yes, the Ui_form is the interface class via qtdesigner and should I post that too?

                      ok, but the code is not complete, there is only the definition of a class ...
