I am using python 2.6.6
I am simply trying to restart the program based on user input from the very beginning. thanks
import random
import time
print "You may press q to quit at any time"
print "You have an amount chances"
guess = 5
while True:
chance = random.choice(['heads','tails'])
person = raw_input(" heads or tails: ")
print "*You have fliped the coin"
time.sleep(1)
if person == 'q':
print " Nooo!"
if person == 'q':
break
if person == chance:
print "correct"
elif person != chance:
print "Incorrect"
guess -=1
if guess == 0:
a = raw_input(" Play again? ")
if a == 'n':
break
if a == 'y':
continue
#Figure out how to restart program
I am confused about the continue statement. Because if I use continue I never get the option of "play again" after the first time I enter 'y'.
Use a continue statement at the point which you want the loop to be restarted. Like you are using break
for breaking from the loop, the continue
statement will restart the loop.
Not based on your question, but how to use continue
:
while True:
choice = raw_input('What do you want? ')
if choice == 'restart':
continue
else:
break
print 'Break!'
Also:
choice = 'restart';
while choice == 'restart':
choice = raw_input('What do you want? ')
print 'Break!'
Output :
What do you want? restart
What do you want? break
Break!
I recommend:
- Factoring your code into functions; it makes it a lot more readable
- Using helpful variable names
- Not consuming your constants (after the first time through your code, how do you know how many guesses to start with?)
.
import random
import time
GUESSES = 5
def playGame():
remaining = GUESSES
correct = 0
while remaining>0:
hiddenValue = random.choice(('heads','tails'))
person = raw_input('Heads or Tails?').lower()
if person in ('q','quit','e','exit','bye'):
print('Quitter!')
break
elif hiddenValue=='heads' and person in ('h','head','heads'):
print('Correct!')
correct += 1
elif hiddenValue=='tails' and person in ('t','tail','tails'):
print('Correct!')
correct += 1
else:
print('Nope, sorry...')
remaining -= 1
print('You got {0} correct (out of {1})\n'.format(correct, correct+GUESSES-remaining))
def main():
print("You may press q to quit at any time")
print("You have {0} chances".format(GUESSES))
while True:
playGame()
again = raw_input('Play again? (Y/n)').lower()
if again in ('n','no','q','quit','e','exit','bye'):
break
You need to use random.seed
to initialize the random number generator. If you call it with the same value each time, the values from random.choice will repeat themselves.
After you enter 'y', guess == 0
will never be True.
