cancelling open dialog gives empty string - rwahdan - Jul-01-2021 Hi, I am trying to open a file using the file dialog but what if the user decides to press cancel? a new line is added to my text widget. I don't want that extra line added there, how to achieve that? text_file = filedialog.askopenfilename(initialdir="C:/Documents", title="Open File", filetypes=(("Text Files", "*.txt"),("HTML Files", "*.html"), ("Python Files", "*.py"), ("All Files","*.*"))) if (len(text_file) !=0): my_text.delete("1.0", END) open_status_name = text_file name, file_extension = os.path.splitext(text_file) name = name.split('/')[-1].split('.')[0] root.title(name+file_extension) status_bar.config(text = "File Opened Successfully! ") text_file = open(text_file,"r") stuff = text_file.read() my_text.insert(END, stuff) text_file.close() else:what i need to do in the else statement to delete that extra line because the user cancelled the operation? Thanks RE: cancelling open dialog gives empty string - deanhystad - Jul-01-2021 Prefix your question with what GUI you are using. Better yet, make your example code complete so others can run it. I don't see where you are adding anything to a text widget if text_file is empty. RE: cancelling open dialog gives empty string - steve_shambles - Jul-17-2021 Assuming this code is in a function (it probably should be), then; if text_file = "": returnafter the filedialog line.
