How to read line by line for the "data" attribute ? Python

Question

anyone know how do i read the "data" line by line?. My goal is to read the data line by line and send it to somewhere when pressing "send". Currently i'm able to read the data but it doesn't read as line by line.

What i've done

    def mouseHover(event):
        x = lbox.curselection()[0]
        file = lbox.get(x)
        self.s.send(("fdown~" + file).encode("utf-8")) 
        self.s.recv(1024).decode("utf-8")

        self.s.send("OK".encode("utf-8"))
        open(file , 'wb+')  #must have
        global data
        data = (self.s.recv(1024).decode("utf-8") ) 
        sys.stdout.flush()
        self.text.insert(tk.END, data)
    lbox.bind("<<ListboxSelect>>", mouseHover)

One could do something like this:

lines = [entry.strip() for entry in open("filename.txt", "r")]

for line in lines:
    [Do whatever]
