Tkinter function print in GUI

Question

I have done a program with 2 apis that show forecast and city info of diffrent citys that the user choose. But now I need help cause Im stuck on how to get my make_request, make_requests and city_data to print the info in the GUI! I think I need a Label but I dont know how to do it, any tips/help would be great! Thanks:

from tkinter import *
import requests
import json

    class Application(Frame):

        def __init__(self, master=None):
            Frame.__init__(self, master)
            self.root = master
            self.pack()
            self.create_widgets()


        def create_widgets(self):
            self.var = StringVar()
            self.countryImage = Label(self, textvariable=self.var, text=self.var.get)
            self.countryImage.pack(side="top")

            self.var.set("The Tripinator" '\n' "Welcome to Tripinator!" '\n' "To get forecast, enter a country and city then press forecast." '\n'"To get tips, JUST enter city then choose beetween Eat / Drink / Party / Shop / Outdoor!")
            self.var.get()

            self.enterCountry = StringVar()
            self.inputCountry = Entry(self, textvariable=self.enterCountry)
            self.inputCountry.pack(side="left")

            self.enterCountry.set("Enter Country")
            self.enterCountry.get()
            self.inputCountry.focus_set()

            self.v = StringVar()
            self.e = Entry(self, textvariable=self.v)
            self.e.pack(side="left")

            self.v.set("Enter City")
            self.v.get()
            self.e.focus_set()

            self.preCategory = StringVar()
            self.enterCategory = Entry(self, textvariable=self.preCategory)
            self.enterCategory.pack(side="left")

            self.preCategory.set("Eat/Drink/Party/Shop/Outdoor")

            self.enterDay = Entry(self, textvariable=self.preDay)
            self.enterDay.pack(side="left")

            self.preDay.set("Enter day")
            self.preDay.get()
            self.enterDay.focus_set()

            self.preTime = StringVar()
            self.enterTime = Entry(self, textvariable=self.preTime)
            self.enterTime.pack(side="left")

            self.preTime.set("morning/midday/evening/night/latenight")
            self.preTime.get()

            self.QUIT = Button(self, text="QUIT", command=self.root.destroy)
            self.QUIT.pack(side="left")

    rot = Tk()

    rot.title("The Tripinator")

    app = Application(master=rot)
    app.mainloop()

What do you mean by you "don't know how to do it"? What is it you don't understand? Did you create the code that creates the Entry widgets? Labels are only slightly different then Entry widgets; if you can create one you should be able to create the other. — Bryan Oakley

I can create a Label but I dont know how to make the requested apis to get printed in the gui. Dont know what to call on cause every time I do a label and call on make_requests nothing happens — user3057339

You have Label even with StringVar in your code and you don't know how to use it ? Strange. — furas

If you just want to simulate printing to the console, you should use a text widget. The text widget is the right choice for showing multi-line data. Instead of calling print, you call insert:

def create_widgets(self):
    ...
    self.out = Text(self)
    ...

def make_request(self):
    r = requests.get(...)
    data = r.json()
    self.out.insert("end", data)
    ...

If you want to show just a few pieces of data, you can use label widgets, and change what appears in them using the config method. For example:

def create_widgets(self):
    ...
    self.label1 = Label(self, ...)
    self.label2 = Label(self, ...)

def make_request(self):
    ...
    self.label1.configure(text=something)
    self.label2.configure(text=something_else)

Example - I use existing label with title to set information from request

def make_request(self):
    r = requests.get("http://api.wunderground.com/api/61418d709872f773/forecast/q/" + self.enterCountry.get() +"/" + self.v.get() +".json")
    data = r.json()
    for day in data['forecast']['simpleforecast']['forecastday']:
        self.var.set( day['date']['weekday'] + ":" + "\n" + "Conditions: " + day['conditions'] + "\n" + "High: " + day['high']['celsius'] + "C " + "Low: " + day['low']['celsius'] + "C" )
    return data
