I am making a Dichotomous Key program where it asks questions to determine the name of the creature that is in question. Here is how it looks like right now:
step = 0
yes = ["y", "yes"]
no = ["n", "no"]
while step == 0:
q1 = input("Are the wings covered by an exoskeleton? (Y/N) ")
q1 = q1.lower()
if q1 in yes:
step += 1
elif q1 in no:
step += 2
else:
print("Huh?")
How would I put the if and else statement into a function so that I can reuse it for every question asked and change the step variable?
-Thanks
This is a working example:
step = 0
def update_step(q):
yes = ["y", "yes"]
no = ["n", "no"]
global step
if q in yes:
step += 1
elif q in no:
step += 2
else:
print("Huh?")
while step == 0:
q = input("Are the wings covered by an exoskeleton? (Y/N)")
update_step(q.lower())
print(step)
But i don't think it's a good way to solve the problem
UPDATE:
I like simplicity, that's why I try to get rid of state whenever I can. For example, I would write it this way:
total_steps = 0
def is_yes(answer):
return answer in ["y", "yes"]
def is_no(answer):
return answer in ["n", "no"]
def get_steps(answer):
if is_yes(answer):
return 1
elif is_no(answer):
return 2
return 0
while True:
answer = input('question? ')
steps = get_steps(answer.lower())
if steps == 0:
continue
total_steps += steps
break
print(total_steps)
you can make it better using more advanced techniques, but let's keep it simple :)

Could you, please, help me to understand how should I use try/except block and count tries at the same time.
Here is the code without try/except block (it seems it's working fine):
import random
number = random.randint(1, 10)
tries = 3
name = input('Hi! What is your name?\n')
answer = input(f'{name}, let\'s play a game! Yes or No?\n')
if answer == 'Yes':
print(f'But be aware: you have only {tries} tries!\nReady?')
chat = input('')
print('Ok, guess a number from 1 to 10!')
while tries != 0:
choice = int(input('Your choice: '))
tries -= 1
if choice > number:
print('My number is less!')
elif choice < number:
print('My number is higher!')
else:
print('Wow! You won!')
break
print(f'You have {tries} tries left.')
if tries == 0 and choice != number:
print(f'Sorry, {name}, you lost... It was {number}. Try next time. Good luck!')
else:
print('No problem! Let\'s make it another time...')
This one is with try/except block.. Not sure where should I place 'choice' variable and where count 'tries', it keeps looping and looping:
import random
number = random.randint(1, 10)
tries = 3
name = input('Hi! What is your name?\n')
answer = input(f'{name}, let\'s play a game! Yes or No?\n')
if answer == 'Yes':
print(f'But be aware: you have only {tries} tries!\nReady?')
chat = input('')
print('Ok, guess a number from 1 to 10!')
while True:
try:
choice = int(input('Your choice: '))
if 0 < choice < 11:
while tries != 0:
tries -= 1
if choice > number:
print(f'My number is less!')
elif choice < number:
print(f'My number is higher!')
else:
print('Wow! You won!')
break
print(f'You have {tries} tries left.')
if tries == 0 and choice != number:
print(f'Sorry, {name}, you lost... It was {number}. Try next time. Good luck!')
else:
print(f'Hey {name}, I said, print a number from 1 to 10!')
except ValueError:
print('Please, enter a number!')
else:
print('No problem! Let\'s make it another time...')
Thanks!
Basically i need to make a game im python that can have a arbitrarily number of people that alternatly answers a multiplication question. But my issue is that i dont know how to keep it running until i hit 30 points. Ive tried to use dict's where the key is the player name and the value is the score. But it stops after the script only has ran once. I tried with a while loop but it went on forever. please help!
import random as r
n = int(input("Insert number of players: "))
d = {}
for i in range(n):
keys = input("Insert player name: ")
#to set the score to 0
values = 0
d[keys] = values
#to display player names
print("Player names are:")
for key in d:
print(key)
for value in d.values():
if value < 30:
random1 = r.randint(0,9)
random2 = r.randint(0,9)
print(f"The two numbers you should multiplie is {random1} and {random2}")
correct = random1*random2
user_inp = input("Insert answer: ")
user_inp = int(user_inp)
if user_inp == correct:
print("Correct!")
d[keys] += 1
else:
print("Wrong!")
d[keys] -= 2
else:
break
I think this will work
winner = False
while not winner :
for value in d.values():
if value < 30:
random1 = r.randint(0,9)
random2 = r.randint(0,9)
print(f"The two numbers you should multiplie is {random1} and {random2}")
correct = random1*random2
user_inp = input("Insert answer: ")
user_inp = int(user_inp)
if user_inp == correct:
print("Correct!")
d[keys] += 1
else:
print("Wrong!")
d[keys] -= 2
else:
winner = True
break
So I tried to make a game where the computer chooses a random 4 digit number out of 10 given numbers. The computer then compares the guess of the user with the random chosen code, and will give feedback accordingly:
G = correct digit that is correctly placed
C = correct digit, but incorrectly placed
F = the digit isn't in the code chosen by the computer
However, the feedback doesn't always output correctly.
Fox example, when I guess 9090, the feedback I get is F C F, while the feedback should consist of 4 letters.... How can I fix this?

name = None

def main():

global guess

In the last line of my code. I am displaying the question, users answer and the correct answer. However, when i add in the answer section at the end it gives me an index out of range error. I can't seem to workout the issue. Can anyone help?

Try it like this and don't worry about indexing, you can add flavor text where you intended:
from random import shuffle
questions = ["10x2","4-2","6+12","6x4","12-5","6+54","1x0","3-6","4+0","65-9"]
answers = ["20","2","18","24",'7','60','0','-3','4','56']
combo = dict(zip(questions, answers))
shuffle(questions)
score = 0
listing = []
for q in questions:
print(q)
ans = input()
if ans == combo[q]:
score += 1
listing.append((q, ans, combo[q]))
print(score / 10)
for item in listing:
print('For question {} you answerd {} and correct answer is {}'.format(*item))
Does anybody know why the score counter isn't working in this program? The program is designed to run 10 random maths questions and then display the score. However although it asks the questions, it will always display the score as being '0'
name = input('Type in your name')
questioncount = 0
score = 0
import random
for questioncount in range(0,10):
number1 = random.randrange(1,13)
number2 = random.randrange(1,13)
sign = random.randrange(1,4)
if (sign) == 1 :
print('{}x{}'.format(number1, number2))
elif (sign) == 2 :
print ('{}+{}'.format(number1, number2))
elif (sign) == 3 :
print ('{}-{}'.format(number1, number2))
answer = input('What is the answer?')
if (sign) == 1:
if (answer) == number1*number2:
score == score+1
else:
pass
if (sign) == 1:
if (answer) == number1+number2:
score == score+1
else:
pass
if (sign) == 1:
if (answer) == number1-number2:
score == score+1
else:
pass
pass
print('you got {} answers right!'.format(score))
There are some problems:
You forgot to change the numbers in the if statements.
You have to parse the input of the answer into int because input returns a string.
score == score+1 is a comparison and it always returns false. It should be "=". score = score + 1 or in a shorter way score += 1 is exactly the same
2 ifs nested for just one thing could be written in the same if statement.
You wrote this:
if (sign) == 2:
if (answer) == number1+number2:
score += 1
else:
pass
It could be:
if (sign) == 2 and (answer) == number1+number2:
score += 1
You should use if/elif statements instead of else:pass
This way
if (sign) == 1 and (answer) == number1*number2:
score += 1
elif (sign) == 2 and (answer) == number1+number2:
score += 1
elif (sign) == 3 and (answer) == number1-number2:
score += 1
and even better
if (sign == 1 and answer == number1 * number2) or (sign == 2 and answer == number1 + number2) or (sign == 3 and answer == number1 - number2) :
score += 1
That said, I would write this program like this:
import random
name = input('Type in your name\n')
score = 0
for _ in range(10):
number1 = random.randrange(1,13)
number2 = random.randrange(1,13)
sign = random.choice(["*", "+", "-"])
expression = "{0} {1} {2}".format(number1,sign,number2)
print(expression)
answer = int(input('What is the answer?\n'))
print("-------------")
if answer == eval(expression):
score += 1
print('{}, you got {} right answers!'.format(name, score))
Notes:
The use of _ it's because it is not important. You can call it whatever you want and you don't even have to declare it before.
The \n means carriage return.
You should do some more changes to prevent user from writting others characters in the answer, but I think you have work enough to do with this.
