The Image will not Show in a Loop, Why not? - image

Question

(Skip to hash-tags if in a hurry)
This program will only work if it ends on the image showing.
I want to use it as a function inside another looping program, but it will not work. It will display the stats of the Pokemon(p.whatever), but the image will not show. The image will show in IDLE Python 3.4, but not the terminal. I've been stuck on this for months.
Here is the program that works(in IDLE Python 3.4, not the terminal):
import pykemon
print('What are you looking for?')
askedpokemon = input()
pokemonInDatabase = False
while pokemonInDatabase == False:
pokemonInDatabase = True
try:
if ('1' in askedpokemon) or ('2' in askedpokemon) or ('3' in askedpokemon) or ('4' in askedpokemon) or ('5' in askedpokemon) or ('6' in askedpokemon) or ('7' in askedpokemon) or ('8' in askedpokemon) or ('9' in askedpokemon):
p = (pykemon.get(pokemon_id = askedpokemon))
else:
askedpokemon = askedpokemon.lower()
p = (pykemon.get(pokemon = askedpokemon))
#Turns askedpokemon into number
askedpokemon = p.resource_uri
askedpokemon = askedpokemon.replace('/api/v1/pokemon/',' ')
askedpokemon = askedpokemon.replace('/',' ')
askedpokemon = askedpokemon.strip()
except pykemon.exceptions.ResourceNotFoundError:
print(askedpokemon + " is not a valid Pokemon name or id number.")
print('Try another')
askedpokemon = input()
pokemonInDatabase = False
print (p)
pTypes = (p.types)
for key, value in pTypes.items() :
pTypes = str(key)
print (' Type: ' + pTypes)
print (' HP: ' + str(p.hp))
print (' Attack: ' + str(p.attack))
print ('Defense: ' + str(p.defense))
print (' Sp Atk: ' + str(p.sp_atk))
print (' Sp Def: ' + str(p.sp_def))
print (' Speed: ' + str(p.speed))
print ('Exp Yield: ' + str(p.exp))

Here is an mcve that illustrates the problem. Call the file tem.py.
import tkinter as tk
root = tk.Tk()
image = tk.PhotoImage(file='python.png')
label = tk.Label(image=image)
label.pack()
When you run in a terminal, this runs, but the root window closes after label.pack(), before you can see it. Either put root.mainloop() at the end of the code or run with python -i tem.py (as IDLE, in effect, does). The -i says to switch from batch to interactive mode after the end of the program instead of closing. IDLE does this so one can interact with the live program before it is closed.
