Computer picks a random word and player has to guess it.

Nov 24th, 2008

How do I get python to pick a random word? Do I have to link it with a dictionary? If so how do you do that.
Exercise from Python Programming for the absolute beginner
Create a game where computer picks a random word and player has to guess the word. Computer tells the player how many letter are in the word. The computer can only respond yes or no. Then the player must guess the word.

This is not very hard if you use the random module.

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
import random
 
words = ['hello','python','monday','tuesday','friday','ice']
choice = random.choice(words)
 
print "Guess the word!"
guess = raw_input()
while guess.lower() != choice:
    print "sorry, not correct"
    guess = raw_input()
print "well dont that was it!"
import random

words = ['hello','python','monday','tuesday','friday','ice']
choice = random.choice(words)

print "Guess the word!"
guess = raw_input()
while guess.lower() != choice:
    print "sorry, not correct"
    guess = raw_input()
print "well dont that was it!"

Make it idiot proof and someone will make a better idiot.

But aren't you limiting to those list of words - hello, python, monday, tuesday, friday, and ice. How do you do for like a dictionary amount of words is it even possible?

There is an English dictionary file attached to:
http://www.daniweb.com/forums/post160495-8.html

The file contains one English word per line, so pick one at random.

May 'the Google' be with you!

Here is a random word generator for this dictionary file

 python Syntax (Toggle Plain Text) 
from os.path import getsize
from random import randint
 
dic_path ="DictionaryE.txt"
file_size =getsize (dic_path )
file_in =open (dic_path ,"rb")
 
def random_word ():
  while True :
    offset =randint (0 ,file_size )
    file_in .seek (offset )
    L =file_in .read (25 ).split ("\r\n")
    if len (L )>2 :
      return L [1 ]
 
if __name__ =="__main__":
  n =100
  print "%d randomly generated words"%n
  for i in xrange (n ):
    print random_word (),
  print
  file_in .close ()
from os.path import getsize
from random import randint

dic_path ="DictionaryE.txt"
file_size =getsize (dic_path )
file_in =open (dic_path ,"rb")

def random_word ():
  while True :
    offset =randint (0 ,file_size )
    file_in .seek (offset )
    L =file_in .read (25 ).split ("\r\n")
    if len (L )>2 :
      return L [1 ]

if __name__ =="__main__":
  n =100
  print "%d randomly generated words"%n
  for i in xrange (n ):
    print random_word (),
  print
  file_in .close ()

Note that the file is opened but not read in memory. Only 25 characters are read at a time when a random word is requested.

For a french version of the game, this site http://www.pallier.org/ressources/dicofr/dicofr.html gives a text file of 336531 french words

Ran the above program I get the following error message "There's an error in your program ** ' return outside function (random_word.py, line 13.)
Line 13 - return L [1 ]
What does that message mean "return outside function"?

That will mean that the return is not being properly recognised as inside of the function. This could be an indenting problem or just accidentally having a return statement somewhere else in your program that isnt a function.

here is something that will raise that error

 Help with Code Tags 
 python Syntax (Toggle Plain Text) 
def add(x,y):
    z = x+y
return z
def add(x,y):
    z = x+y
return z

this will work though

def add(x,y):
    z = x+y
    return z
def add(x,y):
    z = x+y
    return z

So what is wrong with this code especially line 14 -
There's an error in your program *** 'return' outside function (random_word.py , line 14.)

see the indentation of line 14 and line 13 and line 12 and line 11 do not match the indentation needed to set them all inside the function. You just need to re-write this in a python editor and it should auto-indent it for you.

it should be
