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.

    Hello Phil, yes 
     from PyQt5.QtGui import * from PyQt5.QtWidgets import * from PyQt5.QtCore import * from .apr import Ui_Form import os class appr(QWidget, Ui_Form): def __init__(self, parent=None): super(appr, self).__init__(parent) self.setupUi(self) self.center() self.traitement() self.action() def traitement(self): self.textLicence.setVisible(False) self.text = open("Licence.txt","r") self.text.read() self.textLicence.setPlainText(self.text) def action(self): self.licence.clicked.connect(self.showLicence) def showLicence(self): self.textLicence.setVisible(True) self.lab3.setVisible(False) def center(self): qr = self.frameGeometry() cp = QDesktopWidget().availableGeometry().center() qr.moveCenter(cp) self.move(qr.topLeft())


    and the main file outside of this folder.

    Thank you very much for getting back to me, Phil.

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

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

          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, 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.

              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")

                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")

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

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

                          we are on and which version of Python ...
