[Tutor] Loop
Hello. Right now I am learning the python language through Python Programming
for the Absolute Beginner 3rd Edition. I am having trouble with one question in
Ch. 3 #2, which says "Write a program that flips a coin 100 times and then
tells
you the number of heads and tails." Right now I am having trouble connecting
the
random.randint function into the loop.
# Coin
import random
# Set up Values
coin = random.randint(1,2)
tails = 0
heads = 0
if (coin == 1):
tails += 1
else:
heads += 1
toss = 0
while toss < 100:
toss += 1
coin = input(random.randint(1,2)
print("Toss Count:", count)
print("Tails:", tails)
print("Heads:", heads)
input("\n\nPress the enter key to exit.")

[Tutor] Python Beginners
Hello. Right now I am learning the python language through Python Programming
for the Absolute Beginner 3rd Edition. I am having trouble with one question in
Ch. 4 #3, which says "Improve 'WordJumble so that each word is paired with a
hint. The player should be able to see the hint if he or she is stuck. Add a
scoring system that rewards players who solve a jumble without asking for the
hint'".
Right now I am having trouble with giving the 'hint' variable a value despite
the conditions. Everything else is working fine.
# Word Jumble
#
# The computer picks a random word and then "jumbles" it
# The player has to guess the original word
import random
# create a sequence of words to choose from
WORDS = ("python", "jumble", "easy", "difficult", "answer", "xylophone")
# pick one word randomly from the sequence
word = random.choice(WORDS)
# create a variable to use later to see if the guess is correct
correct = word
# create a jumbled version of the word
jumble =""
while word:
position = random.randrange(len(word))
jumble += word[position]
word = word[:position] + word[(position + 1):]
# hints for each word
hint = None
if word == "python":
hint = ("It's a snake!!")
elif word == "jumble":
hint = ("Shake Those Words!")
elif word == "easy":
hint = ("Not Hard!")
elif word == "difficult":
hint = ("Not Easy!")
elif word == "answer":
hint = ("I ask a question you have an...")
elif word == "xylophone":
hint = ("Metal bars with two drum sticks")
# start the game
print(
"""
Welcome to Word Jumble!
Unscramble the letters to make a word.
(Press the enter key at the prompt to quit.)
"""
)
print("The jumble is:", jumble)
print("\nFor a hint, type in 'yes'. If not, type in 'no'.")
helpcount = 0
help = input("Do you need a hint?: ")
if help == "yes":
print(hint)
helpcount += 1
guess = input("\nYour guess: ")
elif help == "no":
guess = input("\nYour guess: ")
while guess != correct and guess != "":
print("Sorry, that's not it.")
guess = input("Your guess: ")
if guess == correct:
print("That's it! You guessed it!")
if helpcount == 0:
print("And you didn't even need a hint! You're awesome!\n")
print("Thanks for playing.")

[Tutor] Q
For the Absolute Beginner 3rd Edition book, I am having trouble with another
question, which says "create a game where the computer picks a random word and
the player must guess that word. The computer tells the player how many letters
are in the word. Then the player gets 5 chances to ask if a letter is in the
word. The computer can only respond with 'yes' or 'no'. The player must then
guess the word."
In the "Loop of Game" section of my code for some reason it gives me five more
chances than I wanted it to. When I put two as the chance limit, it allowed
seven. Also, the program will always say "yes" to any letter I enter, even if
it's wrong.
#Word Guess
import random
Aquino
# create a sequence of words to choose from
WORDS = ("python", "jumble", "easy", "difficult", "answer", "xylophone")
# pick one word randomly from the sequence
word = random.choice(WORDS)
# create a variable to use later to see if the guess is correct
correct = word
# Getting the letter count and selection
lcount = len(correct)
LETTERS = None
if correct == "python":
LETTERS = "python"
elif correct == "jumble":
LETTERS = "jumble"
elif correct == "easy":
LETTERS = "easy"
elif correct == "difficult":
LETTERS = "difficult"
elif correct == "answer":
LETTERS = "answer"
elif correct == "xylophone":
LETTERS = "xylophone"
#Start Game
print("\n\n This word has", lcount,"letters in it.")
#Loop of Game
chances = 0
while chances < 5:
guess = input("Does the word have a: ")
for letter in correct:
if letter.lower() in LETTERS:
print("\nYes")
chances += 1
guess = input("\nDoes the word have a: ")
else:
print("\nNo")
chances += 1
guess = input("\nDoes the word have a: ")
print("\nYour chances are up!")
theguess = input("What is your guess?: ")
if theguess == correct:
print("\n\nYou did it!")
input("\n\nPress the Enter key to exit.")
else:
print("\n\nSorry the word is:", correct)
print(("Try again!"))
input("\n\nPress the Enter key to exit.")___

[Tutor] Lists
I'm stuck on two problems from the Absolute Beginners book. The first is
simple.
I am trying to print all the words in the list in random order without repeats,
but it always shows None for some reason.
#Program prints list of words in random order with no repeats
import random
#List of words
list = ["first", "second", "third", "fourth","fifth"]
#Randomize word order
order = random.shuffle(list)
#Print words in random order
print(order)
input("\n\nPress the Enter to exit")
The other question is: "Improve the program by adding a choice that lets the
user enter a name and get back a grandfather. You should still only use one
list
of son-father pairs. Make sure to include several generations in list so a
match
can be found." The only thing I have done is adding choice 5 with its basic
elif
block and adding another name in each of the three sequences in the list, but I
am completely stuck otherwise.
#User can enter name of male and name of his father will show
#Allow user to add, replace, and delete son-father pairs.
#Also have the user enter a name to get back a grandfather
#Setting values
sondad = {"Vincent": "Ramon": "Lolo","Jesus": "God": "Unknown", "Simba":
"Mufasa": "Lion"}
choice = None
while choice != "0":
print(
"""
Who's Your Daddy?!
0 - Quit
1 - Look Up Pair
2 - Add a Pair
3 - Replace a Pair
4 - Delete a Pair

)
choice = input("Choice: ")

print("Good-bye.")

choice = input("Which pair do you want to look up?: ")

# add a father
elif choice == "2":
choice = input("Who is the son you want to add?: ")
if choice not in sondad:
dad = input("\nWho's the father?: ")
sondad[choice] = dad
print("\n", dad, "has been added.")
else:
print("\nThat pair already exists! Try replacing them.")
# replace a father
elif choice == "3":
choice = input("Which son do you want to replace a father?: ")
if choice in sondad:
dad = input("Who's the father?: ")
sondad[choice] = dad
print("\n", choice, "has been replaced.")
else:
print("\nThey don't exist! Try adding them.")
# delete a pair
elif choice == "4":
choice = input("Which pair do you want to delete?: ")
if choice in sondad:
del sondad[choice]
print("\nOkay, I deleted", choice)
else:
print("\nI can't do that!", choice, "don't exist.")

[Tutor] step value
I am stuck on a question for Absolute Beginner's. I googled this and there have been others who have not understood the question and I am also not clear on the question he is asking. This function is a part of a tic tac toe program."Improve the function ask_number() so that the function can be called with a step value.

[Tutor] Step Value
I am still working on that one question in the absolute beginners with the the
ask_number function and step value. Honestly, I still have no idea what to do.
This is one of my many attempts, but I know that it's wrong.

"""Ask for a number within a range."""
response = None
if response in range(low, high, 1):
return response
while response not in range(low, high):
response = int(input(question))
return response
I tried to find clues by looking at the later section that calls on the
ask_number function:
def human_move(board, human):
"""Get human move."""
legal = legal_moves(board)
move = None
while move not in legal:
move = ask_number("Where will you move? (0 - 8):", 0, NUM_SQUARES)

another.\n")

"From Steven D'Aprono:

Okay, I think I understand it better for the quesiton:
"Improve the function ask_number() so that the function can be called with a

and the human_move function that calls it later on. The thing I am unaware of
doing is making the step value 'optional rather than required' though.

I have to improve the trivia_challenge program so each question has a different point value. I added a point into the text file after each category line, so the next_block() can call it.

Re: [Tutor] Television
It's working better now. The problem I have left is that I have to set the
channel and volume values in a range (for both I intend for 0-10). I thought
the range() would be the choice, but probably I'm not using it right.
Another one is for the tv.channel to hold a new value instead of just
adding/subtracting the value and the only way I can think how is to use a
list and then have the function replace the value each time. I'm sure there
is a better way though.

Re: [Tutor] Television
I made in elif statement for the channel changer that works for it, but the
volume systems system boundary does not the way I want it to. If the volume
is 2 and I lower it by a value of 5, it will accept the volume at a negative
number thus going past the boundary. The vice-versa for the high boundary as
well.

[Tutor] Critter
I'm on the Critter Caretake problem that involves handling more than one critter. I have looked At David Merrick's threads for some answers, but the difference is that he created a whole new class to handle it, while I only made more critter objects. The only problem I have left is to have my actions (play and eat) apply to all my creatures ALL AT ONCE, instead of one at a time like it is in my code right now. http://old.nabble.com/file/p31933791/critter_caretaker3.py critter_caretaker3.py -- View this message in context: http://old.nabble.com/Critter-tp31933791p31933791.html Sent from the Python - tutor mailing list archive at Nabble.com. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Critter
Last thing I need to do solve is the __str__ problem. I can print the name
fine, but everytime I try to put in the self.hunger and self.boredom values
I get:
TypeError: Can't convert 'int' object to str implicitly

[Tutor] War: The Card Game
I am working on the card game of war challenge where each player is given a single card and the highest value wins. I keep getting a Type Error since for the moment since the values of the cards cannot be compared due to their types. I am thinking of creating a Card_Value class that will give each rank and suit a certain value. If there is also a more elegant way of handling some of the code in the main section that will be welcome. http://old.nabble.com/file/p31961149/war.py war.py -- View this message in context: http://old.nabble.com/War%3A-The-Card-Game-tp31961149p31961149.html Sent from the Python - tutor mailing list archive at Nabble.com. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Blackjack Betting
I was able to get the program started without errors now. What is left now is to: Having the stash change after winning and losing. No matter what, the value in stash stays the same. The conditional statement I made which prevents players with no money from playing is dependent on this. After each game when I choose to play again, the betting options do not come up again before the cards are drawn. Apply the betting option to more than one player the same way each player can choose to hit. I think the key involves modifying the init function in class BJ_Game, where it adds the number of players and names. http://old.nabble.com/file/p31977263/blackjackbetting.py blackjackbetting.py Emile van Sebille wrote: > > On 7/1/2011 12:51 AM Andre Engels said... > >> In this case, the error message says: >> >> NameError: global name 'bet' is not defined > > Note use of the term global? > >> >> That means, at some time at the program, it is told to do something with >> 'bet', but there is no variable bet.

Also I must be doing something wrong if I have to enter a "bet = Bet()" into each function where it is used. I tried putting Bet into the other classes' arguments but it did not have any effect.
