[liketocode]

Gee...Thx ! I'm still begginer so i miss things that are so obvious

def openFile():
    filepath = filedialog.askopenfilename(initialdir="C:\\Test",
                                          title="Open file okay?",
                                          filetypes=(("text files", "*.txt"),
                                          ("all files", "*.*")))
    if len(filepath) == 0:
        return

    file = open(filepath, 'r')
    print(file.read())
    file.close()
