Can't figure out how to make code 'restart' - python-3.x

Question

I know the line "goto Start" is wrong just put it there, that's where I want the code to loop back to the start of the code but cannot figure out how to do it at all. Please help....
dsides = int(input("how many sides do your dice have?"))
print("Your dice has " + str(dsides) +" sides")
dint = int(input("How many dice do you want to roll?"))
print("You are rolling " + str(dint) + " dice")
import os
answer=0
import random
y=0
while( y < dint ):
out = random.randint(1, int(dsides))
print(str(out))
y=y+1
while (True):
answer = raw_input('Run again? (y/n): ')
if(answer in ("y", "n")):
if(answer == "y" ):
goto start
else:
print("GoodBye")
break
else:
print ("Invalid input.")
break

Answer 1

wrap the code in a function and call the function:
def my_function(output=''): # <-- change 1
dsides = int(input("how many sides do your dice have?"))
print("Your dice has " + str(dsides) +" sides")
dint = int(input("How many dice do you want to roll?"))
import random
y = 0
while y < dint:
out = random.randint(1, int(dsides))
output += "{} ".format(out) # <-- change 2
# print(str(output)) # <-- change 3
y=y+1
while True:
answer = raw_input('Run again? (y/n): ')
if answer in ("y", "n"):
if answer == "y":
my_function(output) # <-- recursive call
else:
print(output) # <-- change 4
print("GoodBye")
return
else:
print ("Invalid input.")
break
Example output:
how many sides do your dice have?6
Your dice has 6 sides
How many dice do you want to roll?6
Run again? (y/n): n
2 1 3 4 6 5
GoodBye
