[Tutor] Random in loop
Hello, Im kinda stuck on something in the book Python
Programming.
The "Challenage" is to make a progam that flips a coin
100 times and then tells you the number of heads and
tails.
here is what i have so far,
Code:
import random
coin = 0
heads = 0
tails = 0
heads_tails = random.randrange(2)
while coin < 100:
coin += 1
if (heads_tails == 0):
heads += 1
elif (heads_tails == 1):
tails += 1
print coin, heads, tails
raw_input("Enter to exit")
I know what my problem is, i just dont know the how to
fix it.
(Or i could just be writing this wrong all together)
If im even goin at this the right way my problem is i
need to randomly pick a new number at the beggening of
each loop but i dont know how! other then that i think
the rest of the code is good? Thanks for any help ^^

Ok so what i have to do is make it so when a player
ask for a hint the program display a hint, heres my
loop, not whole script.
guess = raw_input("\nYour guess: ")
guess = guess.lower()
while (guess != correct) and (guess != ""):
print "Sorry, that's not it."
print "If you need a hint enter help"

The problem is its passing up "Hint" altogether
when the user input is hint it doesn't do anything,

[Tutor] yeah
Hi Hans and Adam, Just wanted to point out: next time, let's try to figure out why Ryan had problems with this, rather than directly give a working answer. For example, we can ask things like: what part did Ryan get stuck on? Was it unfamiliarity with the things we can do with slices, or something else? What did Ryan try? What did Ryan look at? Are there programs that Ryan has written that are similar to the one he's asking about? The reason for the caution is this: the reversal question he asked felt way too much like a homework exercise. I hate being pedantic, but it is something we should be thinking about. yeah, that was something i should know so i whent back and read the whole chapter of the book that told me to write such a program, the problem is i was out of it when i read that part that nothing stuck, ^^ ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] Editing Pickled .dat files
Hello, this is like my 3rd question today lol which is
making up for not asking any for months =P, anyways
I have a pickled .dat file named dictionary, maybe
youv guessed this but its a dictionary of the
Alphabet, the program is a translator right now all it
does is translate the Alpabet (its a stupid made up
language helping someone out cuz i needed a project)
anyways im pretty sure i have the reading the pickled
file, taking input from the user, looking on the word
in the .dat file and printing out the translation,
Here is where im stuck.
I want the program to be able to translate full words
to (the only way i know to do that is to put every
word in the dictionary, aka .dat file)
im not goin to put all the english words and there
translation in there myself! so i have a option for
the user to put there own definitions,
What i need to know is how do i take input from the
user, collect the word and its definitions and then
pickle it into the .dat but editing the dictionary in
the .dat file.
heres my code for reading so you get a better idea of
what i mean
pickle_file = open("dictionary.dat", "r")
dictionary = cPickle.load(pickle_file)
while sentence != "0":
sentence = raw_input("\nInput a english
letter/word to be translated: ")
if sentence in dictionary:
definition = dictionary[sentence]
print "\n", definition

Ohhh ok i got it to work! but why isn't the change
permanent? it is "writing" to the file isn't it.
