Heyy there, How are you?? Welcome to the surprise post!! Today I will help you create your very first Python game, isn’t it exciting?? First of all let me congratulate you on making this far, YOU ARE AMAZING!!! You will go a long way as a python developer. I remember when I reached this point and was so proud of myself thinking that I started with printing ‘Hello, World!’ and now i am going to create my first game.
In this
lesson, you will be creating a text-based game, Hangman. If you have never
played hangman, you can check out the rules here. It is going to be
a lengthy program, so strap in. Here’s how we are going to create hangman, I’ll
provide you with a portion of the code and a picture so you can see exactly
what is going on and then I’ll break down the code line-by-line. So do not
worry, we will put together every piece of the puzzle and create our
very first Python game.
In your
program, the computer will be Player 1 and the person guessing will be Player
2.
So let us
get started.
Here is the
beginning of your Hangman code:
Code 1:
def hang(word):
stages=["",
"_____________ ",
"
| ",
"
| | ",
"
| 0 ",
"
| ",
"
| / | \ ",
"
| ",
"
| / \ ",
"
| "]
wrong=0
remaining_letters=list(word)
board=["_"]*len(word)
win=False
print("Welcome to
Hangman")
Line 1: First you create a function, ‘hangman’ to store the game. The
function accepts the variable called ‘word’
as a parameter, which is the word player 2 has to guess.
Line 2-11: ‘stages’ is a list of strings, printing all the
lines from ‘stages’ forms a hangman, which represents player 2 running out of
guesses and losing the game.
Line 12: The variable ‘wrong’ keeps track of player 2’s incorrect guesses.
Line 13: The variable ‘remaining_letters’ is a list containing each character in the
variable ‘word’, it keeps track of
which letters are left to guess.
Line 14: The variable ‘board’ is a list of
strings. You use it to keep track of the game board you display to player 2.
For example, if the word is ‘Cat’ and player 2 has already guessed ‘C’ and ‘t’,
the board will look like this:
C_t
Line 15: The ‘win’ variable keeps track of whether player 2 has won the game
yet.
Line 16: Finally, you print ‘Welcome to Hangman!’, to start of the
game.
Code 2:
while
wrong<len(stages)-1:
print("\n")
msg="Guess
a letter \n"
char=input(msg)
Line 18: The next part of your code is a loop
that keeps the game going. The loop continues as long as the variable ‘wrong’ is less than the length of the ‘stages’ list – 1. In short, the game will continue until player 2 has
guessed more wrong letters than the number of strings it takes to create a
hangman.
Note: You have to subtract 1 from the
length of the ‘stages’ list to
compensate for the fact that the ‘stages’
list starts counting from 0 and the variable ‘wrong’ starts counting from 1.
Line 19: Once you are inside the loop, you
print a blank space to make the game look nice when it runs In the shell.
Line 20-21: Then, you collect player 2’s guess
and save it in a variable ‘char’.
Code 3:
if
char in remaining_letters:
cind=remaining_letters.index(char)
board[cind]=char
remaining_letters[cind]="£"
else:
wrong+=1
Line 23-28: Next, you check to see if player 2
guessed correctly by seeing if their guess is in the list of ‘remaining_letters’.
Line 23-26: If player 2 guessed correctly, you
need to update your ‘board’ list.
For example, if the word was ‘Boat’ and player 2 guessed ‘B’ then the board
should look like this:
B _ _ _
Line 24: The ‘index()’ function returns the index of the first occurrence of a
character in a list. To update your board, find the first occurrence of the
letter player 2 guessed in the list ‘remaining_letters’
and store it in the variable ‘cind’.
Line 25: You then use that index to replace
the corresponding underscore(_) in the ‘board’
list with the letter they guessed.
Line 26: You replace the letter they guessed
with a ‘$’ in the ‘remaining_letters’ list, so that the
letter which was guessed correctly is no longer in the ‘remaining_letters’ list.
Replacing the letter with a character like dollar sign ($) is easier than
removing it from the list.
Line 27-28: If player 2 guesses incorrectly, you
simply increment the variable ‘wrong’ by
1.
Code 4:
print(("
".join(board)))
e=wrong+1
print("\n".join(stages[:e]))
Line 30: Next, you call the ‘join()’ method on a ‘space’ character and pass it the
variable ‘board’. This prints out
the board so player 2 can see it and use it to make their next guess.
Line 31-32: Then, it is time to print the
hangman. To print your hangman at whatever stage your game is at, you have to
slice your stages list. You start at stage 0 and slice up to the stage you are
at represented by the variable ‘e’ (viz
‘wrong’ +1). You add 1 because when you are slicing the end slice does not
get included in the result.
Code 5:
if
"_" not in board:
print("You
Win!!!")
print("".join(board))
win=True
break
if
not win:
print("\n".join(stages))
print("You
lose. It was {}".format(word))
Line 34-38: Finally you check if there are anymore underscores (_) left in the ‘board’ list, if there aren’t any, it means player 2 has successfully guessed every letter in the word and won the game.
Line 35: When player 2 wins you print ‘You win!’
Line 36: You print
the board one last time.
Line 37-38: Then, you set the variable ‘win’ to True and break out of the loop.
Once you break out of the loop, if player 2 won you do nothing, the program is over.
Line 41: If that is the case, you print the
full hangman and ‘You Lose!’
Line 42: Followed by the word they couldn’t
guess.
This is how the complete program looks like:
def hang(word):
stages=["",
"_____________ ",
" |
",
" |
| ",
" |
0 ",
" | ",
" |
/ | \ ",
" | ",
" |
/ \ ",
" | "]
wrong=0
remaining_letters=list(word)
board=["_"]*len(word)
win=False
print("Welcome to Hangman")
while wrong<len(stages)-1:
print("\n")
msg="Guess a letter \n"
char=input(msg)
if char in remaining_letters:
cind=remaining_letters.index(char)
board[cind]=char
remaining_letters[cind]="£"
else:
wrong+=1
print((" ".join(board)))
e=wrong+1
print("\n".join(stages[:e]))
if "_" not in board:
print("You Win!!!")
print("".join(board))
win=True
break
if not win:
print("\n".join(stages))
print("You lose. It was
{}".format(word))
CONGRATULATIONS !!! You now have created your very own text-based Python game. Feel free to edit the code and make the game look cooler. You can also create games like quizzes and other text-based games. Like I always say, Have fun with it !!! Good luck !!!!
I hope this article answered all of your questions and even helped you in becoming a better programmer. IF IT DID, leave a like AND FOLLOW THIS BLOG TO BECOME A PROFESSIONAL PYTHON PROGRAMMER FROM A TOTAL BEGINNER. IF IT DIDN'T, feel free to ask any further queries in the comment section below.
