I need help in creating a GUI for my python code to program a Hangman. I
have programmed a working code of Hangman, but I need to make it to a
proper program with GUI.
The first thing you need to do is restructure it to separate out the
logic from the UI. Then modify it to be event driven. Then choose a GUI
framework (like Tkinter or wxPython) to actually build the GUI bit.
import random;
import time;
correct_guesses = ['-', ' ']
guessed_letters = []
def Input_Error(input):
if input.isdigit() == True:
print "Input Error. \nIt's Hangman. Your secret word only includes
letters. "
while input.isdigit() == False:
input = raw_input('Guess a letter: ')
if len(input)>1:
print 'Only enter one guess at a time'
You need to remove all the print statements since they won't work in a
GUI. return strings instead so that the GUI framework can call the
function and then display the result in the GUI.
def Get_Random_Word():
global word
word_list = []
for line in open('dictionary.txt'):
word_list=line.split()
wordno=random.randint(0, len(word_list) -1)
word= word_list[wordno]
print word
return word
Same here, remove the print. I assume in this case its only for
debugging anyhow!
def displayBoard():
display = []
i = 0
while i < len(word):
if word[i] in correct_guesses:
display.append(word[i])
if word[i] not in correct_guesses:
display.append('_ ')
i +=1
for w in display:
print w,
O)bviously this will need to be rewritten using the GUI framework of
your choice.
def play():
This will dissappear and be replaced by events from the GUI.
global player_guess
global guess
player_guess = (raw_input('\nGuess a letter: ')).lower()
Input_Error(player_guess)
> guess = 0

So this will be replaced by a user typing a value into a field
(or selecting a letter from a set of buttons?) and as a result calling
an event handler to check for errors. Then checking valid inputs for an
outcome...
correct_guesses.append(player_guess)
elif player_guess not in word and player_guess.isdigit()== False:
You don't need the isdigit since you already checked that in
Input_Error() above
guessed_letters.append(player_guess)
print 'wrong'
guess += 1
if len(correct_guesses)-2 == len(word):
print word
print 'Congratulation, you guessed the word correctly in', guess, 'guesses.'
break
if guess == 8:
break
And this stuff will all be replaced with code that updates results
fields or labels/diagrams on the GUI.
displayBoard()
This will happen automatically when the board changes.
player_guess = (raw_input('\nGuess another letter: ')).lower()
Input_Error(player_guess)
def Welcome():
print """ | | | | /\ | ___ \ / _____) ___ \ /\ | ___ \
| |__ | | / \ | | | | / ___| | _ | | / \ | | | |
| __)| |/ /\ \| | | | | (___) || || |/ /\ \| | | |
| | | | |__| | | | | \____/| || || | |__| | | | |
|_| |_|______|_| |_|\_____/|_||_||_|______|_| |_|
Welcome to Hangman v1.0
Rules:
1. You will have 8 chances to guess the letters correctly.
2. For each wrong guess one chance will be decremented.
3. If you guess the same word again, the chances will not be decremented.
Good luck."""
print "Generating your secret word..."
time.sleep(3)
And this will be built uinto a welcome window/splash-screen.
I also find trouble with the some hangman pic which I have provided
below.
You should probably use images in the GUI version rather than draw the
picture using ASCII art...
You can find more info on event driven coding in my tutor under that
heading.
And you can get basic info on GUI programming in the tutor too.
If you can find a dead-tree version of my tutorial (library?) it has a
chapter with a Tkinter version of hangman as an example program.
HTH.
