Why Doesn't This Code Work, Python 3.0

[jharrison]

I'm finding it hard to make this code work in Python 3.0. Been looking at it for some time now:

# import module for random functions
import random

# List of words for the computer to pick from
words = ("basketball", "football", "hockey", "rugby", "baseball")

# Word to be guessed; picked at random 
word = random.choice(words)
letters_guessed = []

print ("Guess the sport!")
print ("You get to give five letters.")
print ("There are %s letters in the word.") % (len(word))
guesses = 5
while guesses != 0:
letter = input("Enter a letter: ")
if letter in letters_guessed:
print ("You already guessed that letter.")
else:
guesses = guesses - 1
print ("You have %d guesses left.") % (guesses)
letters_guessed.append(letter)


print ("The word:")

masked_word = ""
for letter in word:
if letter in letters_guessed:
masked_word += letter
else: masked_word += "-"
print masked_word
guess = input("Guess the word: ")
if guess == word:
print ("Congratulations, %s is the word!") % (guess)
else:
print ("Nope. The word is %s.") % (word)
input ("Press The Enter Key To Exit")

jharrison,

You have no indentation in the code you posted. It could be as simple as that. What error message do you get when you run the code?

[jharrison]

okay i have the issue solved, when it runs now I get this error message.


Guess the sport!
You get to give five letters.
There are %s letters in the word.
Traceback (most recent call last):
File "C:\Users\Jamo\ Guess The Word.py", line 13, in <module>
print ("There are %s letters in the word.") % (len(word))
TypeError: unsupported operand type(s) for %: 'NoneType' and 'int

I was hoping that you would repost your code using code tags. There is no indentation in the code you posted. That makes it difficult to follow.

I converted to code to run in Python 2.5 and guessed at the indentation:

# import module for random functions
import random
 
# List of words for the computer to pick from
words = ("basketball", "football", "hockey", "rugby", "baseball")
 
# Word to be guessed; picked at random 
word = random.choice(words)
letters_guessed = []
 
print "Guess the sport!"
print "You get to give five letters."
print "There are %s letters in the word." % (len(word))
guesses = 5
while guesses != 0:
    letter = raw_input("Enter a letter: ")
    if letter in letters_guessed:
        print "You already guessed that letter."
    else:
        guesses = guesses - 1
        print ("You have %d guesses left.") % (guesses)
        letters_guessed.append(letter)
 
    print "The word:"
    masked_word = ""
    for letter in word:
        if letter in letters_guessed:
            masked_word += letter
        else: masked_word += "-"
    print masked_word
    
guess = raw_input("Guess the word: ")
if guess == word:
    print "Congratulations, %s is the word!" % (guess)
else:
    print "Nope. The word is %s." % (word)
raw_input ("Press The Enter Key To Exit")

It seems to work.

I think the problem is the parentheses in your print statement. Try changing this:

print ("There are %s letters in the word.") % (len(word))

To this:

print ("There are %s letters in the word." % len(word))

That way the print function gets just one argument, an expression that evaluates to the finished string.

Thanks for the input sockmonk. Invalid parentheses around arguments to the print function would be consistent with the error message. I should have noticed it.
