So I'm trying to make a little hangman game in Python. I've managed it already, but I've seen lots of other people using functions to achieve this. Here's my code without using function:
from hangman_words import word_list
import random
def select_word():
return random.choice(word_list)
hidden_word = select_word()
char_lines = "_" * len(hidden_word)
guessed_letters = []
Lives = 8
game_start = input("Would you like to play HangMan? (Y/N)\n")
if game_start.upper() == "Y":
prompt_user = True
elif game_start.upper() == "N":
print("*Sad Python Noises*")
prompt_user = False
else:
print("You to say 'Yes'(Y) or 'No'(N)")
while (Lives > 0 and prompt_user == True):
user_input = input("Choose a letter!\n\n")
user_input = user_input.upper()
if user_input.upper() in guessed_letters:
print("\nYou have already guessed that letter. Choose something else!")
elif hidden_word.count(user_input) > 0:
for i, L in enumerate(hidden_word):
if L == user_input:
char_lines = char_lines[:i] + hidden_word[i] + char_lines[i+1:]
print("\nCorrect!")
print(char_lines)
else:
guessed_letters.append(user_input)
print("\nNope, that letter isn't in the word. Try again!")
Lives -= 1
if char_lines == hidden_word:
print("Well done! You won the game!")
print(f"You had {Lives} lives remaining and your incorrect guesses were:")
print(guessed_letters)
exit()
print(f"Lives remaining: {Lives}")
print(f"Incorrect guessed letters: {guessed_letters}")
print(char_lines)
if (Lives == 0 and prompt_user == True):
print("You have ran out of lives and lost the game!.....you suck")
if prompt_user == False:
print("Please play with me")
My current code for the version using functions is like this:
from hangman_words import word_list
import random
def select_word():
global blanks
selected_word = random.choice(word_list)
blanks = "_" * len(selected_word)
return selected_word, blanks
def game_setup():
global lives
global guessed_letters
global hidden_word
lives = 20
guessed_letters = []
hidden_word = select_word()
return lives, guessed_letters, hidden_word
def play_option():
game_start = (input("Would you like to play HangMan? (Y/N)\n")).upper()
if game_start == "Y":
global prompt_user
prompt_user = True
game_setup()
return prompt_user
elif game_start == "N":
print("*Sad Python Noises*")
exit()
else:
print("You need to say 'Yes'(Y) or 'No'(N)")
def user_input_check(user_input):
if type(user_input) != str: # [Want to check if unput is of tpye Str]
print("Please input letter values!")
elif user_input != 1:
print("Please only input single letters! (e.g. F)")
else:
pass
def game_board(user_input, hidden_word, guessed_letters, blanks, lives):
if user_input in guessed_letters:
print("You have already guessed that letter. Choose something else!")
elif hidden_word.count(user_input) > 0:
for i, L in enumerate(hidden_word):
if L == user_input:
blanks = blanks[:i] + hidden_word[i] + blanks[i+1:]
print("Correct!")
print(blanks)
else:
guessed_letters.append(user_input)
print("Nope, that letter isn't in the word. Try again!")
lives -= 1
print(f"Lives remaining: {lives}")
print(f"Incorrect guessed letters: {guessed_letters}")
print(blanks)
return
def win_check(blanks, hidden_word, lives, guessed_letters):
if blanks == hidden_word:
print("Well done! You won the game!")
print(f"You had {lives} lives remaining and your incorrect guesses were:")
print(guessed_letters)
exit()
def lives_check(lives, prompt_user):
if (lives == 0 and prompt_user == True):
print("You have ran out of lives and lost the game!.....you suck")
exit()
play_option()
while (lives > 0 and prompt_user == True):
user_input = (input("Choose a letter!\n\n")).upper()
user_input_check(user_input)
game_board(user_input, hidden_word, guessed_letters, blanks, lives)
win_check(blanks, hidden_word, lives, guessed_letters)
lives_check(lives, prompt_user)
I think I should be using classes instead of functions really, but I'd like to get it work with functions first, then try adapting it to work with classes. If I'm using functions, how does return actually work? Does returning variable names put those variables within the global name-space? Or does return only work when you assign the returned value to a global name-space variable? Like this:
def add_one(a):
return a + 1
b = add_one(3) # b = 4
