Should I create a main function, and is everything placed right or should I def more or fewer functions?

import random

# open text file with a word on every new line
# [:-1] removes n, from behind the word, wich is also pulled from the text
with open('sowpods.txt', 'r') as words:
 chosen_word = (random.choice(words.readlines()))[:-1]
right_guess = set()
wrong_guess = set()
lives = ['1up', '2up', '3up', '4up', '5up', '6up']
print('Welcome to hangman.nnEnter a letter to start playing, you have six lives.nGoodluck!')


def progress():
 # for every character in chosen_word
 for i in chosen_word:
 # see if the character is in the players guess
 if i in right_guess:
 # print then out the character
 print(i, end=' ')
 elif not i in right_guess:
 # if not found, print a dash
 print('_', end=' ')


def start():
 while True:

 progress()

 # check if the word has been guessed yet
 if right_guess == set(chosen_word):
 print('nnnCongratulations you've won!')

 # forces the userinput to uppercase
 x = input('nn').upper()

 # check if the letter has already been guessed right
 if x in right_guess:
 print('You've already guessed this letter!')

 # collects all the right guessed letters
 elif x in chosen_word:
 right_guess.add(x)
 print('correctn')

 # check if the letter has already been guessed wrong
 elif x in wrong_guess:
 print('You've already tried this letter.')

 # collect wrong guesses and checks if input is a single entry
 elif not x in chosen_word and len(x) == 1:
 wrong_guess.add(x)
 print('wrong')
 # remove a live from the list when wrong guess
 del lives[0]
 # if all lives gone end game
 if len(lives) > 0:
 print('Lives left:n' + str(len(lives)))
 elif len(lives) <= 0:
 print('You have no more lives left, restart to try again')
 print('Maby you'll get an easier word then:')
 print(chosen_word)
 print('Good luck')

 # for when input isnt a singe entry
 else:
 print('You must enter a singel letter.')

print(start())
