So I have to create a program that asks the user 5 addition questions and they can type the right answer. I am very new at python and functions in general so helpful answers only please. I know how to get random numbers and make it so the question for ex: "What is 4 + 5?" I just do not know how to ask 5 different addition questions within the function. This is what I have.
import random
def add():
num1=random.randint(1,10)
num2=random.randint(1,10)
return num1,num2
def main():
x,y= add()
plus=int(input("What is {} + {} ?".format(x,y)))
main()
I don't get an error when I run your code. Here is an answer for you:
Right now your main() is asking for an input back from the user and each time main() is called it will ask for a different number, so if you like you can do something like this:
for _ in range(5):
main()
But from the sound of it, you want to have the function main() ask all of the questions, namely - something like this:
def main():
for _ in range(5):
x,y = add()
plus = int(input("What is {} + {} ?".format(x,y)))
Simplest is to use a counting loop:
def main():
for i in range(5):
x,y = add()
plus = int(input("What is {} + {} ?".format(x,y)))
The following program demonstrates how to have a program ask five addition questions:
import random
import sys
def main():
for count in range(5):
ask_addition_question()
def ask_addition_question():
numbers = random.randrange(10), random.randrange(10)
answer = get_number('What is {} + {}? '.format(*numbers))
total = sum(numbers)
if answer == total:
print('That is correct!')
else:
print('Actually, the correct answer is {}.'.format(total))
def get_number(query):
while True:
try:
return int(input(query))
except KeyboardInterrupt:
print('Please try again.')
except EOFError:
sys.exit()
except ValueError:
print('You must enter a number.')
if __name__ == '__main__':
main()
Just use a for loop to ask the user 5 times
def main():
for i in range(5):
x,y = add()
plus = int(input("What is {} + {} ?".format(x,y)))
To check if the answer is correct just you can do:
if x + y == plus: print "good"
else: print "bad"

enter code hereThis is the original code that I wrote:
while True:
user_input = (input(">>",))
try:
user_input = int(user_input)
except ValueError:
pass
if user_input in range(1, len(something):
break
I want to put in a method:
`get_user_answer(n: int, p: str) -> int` # This is what the method should look like kind of
#But what should I write here?
def main()
# and how would I call it?
main()
I'm learning about methods so I'm confused
I'm expecting it to work like the code I first wrote, but in a method instead that I call to the main function.
# get user answer function
def get_user_answer():
while True:
user_input = (input(">>",))
try:
user_input = int(user_input)
except ValueError:
pass
if user_input in range(1, len(something):
break
# main function
def main():
# calling get_user_answer function here
get_user_answer()
#calling main function here
main()
Thanks everyone for trying to help, I managed to figure it out. If anyone is interested it was:
def get_user_answer(max_num: int, prompt: str) -> int:
while True:
user_input = input(prompt)
try:
user_input = int(user_input)
except ValueError:
pass
if user_input in range(1, max_num):
break
print(f"Write a number between - {max_num}")
return user_input
I probably didn't give enough information to help me in the best way, now that I think about it, but thanks anyway.
and calling the function to main:
user_input = get_user_answer(len(something), ">>")
I am working on a stupid yet funny practice program to improve my understanding of OOP in Python.
The program is meant to randomly generate some band names from a randomly selected adjective and another randomly selected noun - producing a lot of hilarious band names.
For the most part, the program works fine, but for some reason, there are some problems with the if-statements and the while loop in the menu(self)- method all the way down in the BandList class.
My hypothesis is that there is something wrong with the nesting of the else-if statements, or that the loop doesn't manage to advance the loop when I call on the self._generateBand() method in line 60 due to some technicality I'm not aware of. Either way, I'm not sure.
However, my question is:
Why does my loop stop at the line self._writeBand() and not continue executing the code that follows? (As shown below)
done = False
while done != True:
print("\n=============== BAND NAME GENEREATOR ==================")
start = input("\nDo you want to generate a list of bandnames? (y/n): ")
if start.lower() == "y":
self._generateBand()
self._writeBand() #The loop stops here for some reason and asks the same question over and over.
#The program won't execute this part of the code.
inp = ("\nDo you want to save these band names? (y/n): ")
if inp.lower() == "y":
outfile = input("What do you want to name the file?: ")
self._saveBand(f"{oufile}.txt")
If anyone can help me fix this, I would be super grateful.
In advance: Thank you for your help.
The complete program is pasted in below
import random
class Band:
def __init__(self, name):
self._Bandname = name
def __str__(self):
return f"{self._Bandname}"
def hentName(self):
return self._Bandname
class BandList:
def __init__(self):
self._BandList = []
def _readFile(self, filename1, filename2):
with open(filename1) as infile1, open(filename2) as infile2:
lineAdjective = infile1.read().splitlines()
lineNoun = infile2.read().splitlines()
adjective = random.choice(lineAdjective)
noun = random.choice(lineNoun)
return f"{adjective} {noun}"
def _saveBand(self, filename):
with open(filename, "w") as outfile:
for j, i in enumerate(self._BandList):
outfile.write(f"Nr: {j}\t-{i}\n")
def _generateBand(self):
num = int(input("\nHow many band names would you like to generate?: "))
for i in range(num):
bandname = f"The {self._readFile('adjective.txt', 'noun.txt')}s"
self._BandList.append(Band(name= bandname))
def _writeBand(self):
print("\n========= Genererte bandname =========")
for i in self._BandList:
print(i)
#print(i.hentName())
def _deleteBand(self):
self._BandList.clear()
def _writeGoodbyeMsg(self):
print("\n============ PROGRAM TERMINATING ================")
print("\t- thanks for using the program, goodbye!")
def menu(self):
done = False
while done != True:
print("\n=============== BAND NAME GENEREATOR ==================")
start = input("\nDo you want to generate a list of bandnames? (y/n): ")
if start.lower() == "y":
self._generateBand()
self._writeBand() #This is probably where the bug is...
inp = ("\nDo you want to save these band names? (y/n): ")
if inp.lower() == "y":
utfil = input("What do you want to name the file?: ")
self._saveBand(f"{utfil}.txt")
elif inp.lower() == "n":
self._deleteBand()
inp2 = input("Do you want to generate more band names? (y/n)?: ")
if inp2.lower() == "y":
self._generateBand()
elif inp2.lower() == "n":
done = True
self._writeGoodbyeMsg()
else:
print("Unknown command, please try again")
else:
self._writeGoodbyeMsg()
done = True
if __name__ == '__main__':
new = BandList()
new.menu()
You're missing an input call on your 2nd question for saving the band names. It should be:
inp = input("\nDo you want to save these band names? (y/n): ")
It does work. You just haven't given any values in self._BandList.
Its returning "BandList": null.
I want to get 10 random questions from an web API with many questions, but I dont seem to get it to work. Right now im getting KeyError: 'prompt', but I dont know if the function is correct at all as I have been trying a few diffrent options.
Im also trying to print out in the end which questions you get wrong, but with no luck there either.
import random
import requests
from random import randint
url = ""
the_questions = requests.get(url).json()
print("------ Welcome to Python quiz ------")
def random_question():
data = the_questions['prompt']
random_index = randint(0, len(data)-1)
return data[random_index]['prompt']
def get_correct_answers(answers):
res = []
for ans in answers:
if ans['correct']:
res.append(ans['answer'])
return res
def get_numeric(prompt, max_value,):
while True:
try:
res = int(input(prompt))
except ValueError:
print("Answer only with a number!")
continue
if 0 < res < max_value:
break
else:
print("Invalid answer option!")
return res
def main():
score = 0
for questions in the_questions['questions']:
#print(questions['prompt'])
print(random_question())
for i, a in enumerate(questions['answers'], start=1):
print(f"[{i}] {a['answer']}")
user_answer = get_numeric("> ", len(questions['answers']) + 1)
if questions['answers'][user_answer - 1]['correct']:
score += 1
print(f"Right!")
else:
all_correct = ", ".join(get_correct_answers(questions['answers']))
print(f"Wrong, right is: {all_correct}")
print(f"You got {score} points of {len(the_questions['questions'])} possible!")
if __name__ == '__main__':
main()
Sample of the API
{"questions":[{"id":"1","prompt":"Which functions is used to write out text in the terminal?","answers":[{"answer":"print","correct":true},{"answer":"input","correct":false},{"answer":"import","correct":false},{"answer":"sys.exit","correct":false}]}
Error shows problem with key prompt and you use it only in random_question().
If you use print() to see values in variables random_question() then you will see that you need
data = the_questions['questions']
instead of
data = the_questions['prompt']
As for me name of variables are missleading. You should use name data for all information from API and later questions = data['questions'] could make sense.

My version with random.shuffle()

Can I combine these functions together to shorten my python code? I'm creating a quick program!
Here are the functions:
def try1():
try:
num1=input("Enter num 1: ")
return num1
except ValueError:
print("incorrect!")
return #value
def try2():
try:
num2=input("Enter num 2: ")
return num2
except ValueError:
print ("incorrect!")
return #value
def try3():
try:
num3=input("Enter num 3: ")
return num3
except ValueError:
print ("incorrect!")
return #value
def try4():
try:
num4=input("Enter num 4: ")
return num4
except ValueError:
print ("incorrect!")
return #value
Please post your suggestions and answers below.
As you can see from my reputations, I am a new programmer hoping to find kind people on Stackoverflow.
(This answer is based on the original revision of the question which is no longer accessible but showed a different problem, where the user is keep being asked until a valid number is entered. And the code showed some skill game system or something, so that’s why my questions are longer and more specific too.)
Something like this?
def getInt(name, target):
while True:
try:
return int(input('Please enter {0} for {1}: '.format(name, target)))
except ValueError:
print('Incorrect!')
strength0 = getInt('strength', 'character 1')
skill0 = getInt('skill', 'character 1')
strength1 = getInt('strength', 'character 2')
skill1 = getInt('skill', 'character 2')
In general, when you have multiple functions that approximately do the same thing, then yes, there is a lot potential to refactor it so you don’t repeat yourself. In this case, what was different is the question the user was being asked, so if we parameterize that, we are good to use just a single function to handle it all.
The function can be generalised to ask for the input of any number, for example:
def try_num(n):
num = int(input("Enter num {} : ".format(n)))
while num != n:
print ("incorrect!")
num = int(input("Enter num {} : ".format(n)))
return num
Use it like this:
try_num(10)
Enter num 10 : 9
incorrect!
Enter num 10 : 10
10
def safe_int(x):
try:
return int(x)
except ValueError:
return 0
[safe_int(raw_input("Number %d:"%i)) for i in range(4)]
I would create a validation method and simply pass in the strings.
def validate(question):
while True:
try:
print question,
input = raw_input()
if input.isdigit():
return int(input)
else:
print "Not a valid integer"
I am a beginer python learner. I am trying to create a basic dictionary where random meaning of words will come and user have to input the correct word. I used the following method, but random doesn't work. I always get the first word first and when the last word finishes, I get infinite 'none' until I kill it. Using python 3.2
from random import choice
print("Welcome , let's get started")
input()
def word():
print('Humiliate')
a = input(':')
while a == 'abasement':
break
else:
word()
# --------------------------------------------------------- #
def word1():
print('Swelling')
a = input(':')
while a == 'billowing':
break
else:
word()
# ------------------------------------------------------------ #
wooo = [word(),word1()]
while 1==1:
print(choice(wooo))
is there any faster way of doing this and get real random? I tried classes but it seems harder than this. Also, is there any way I can make python not care about weather the input is capital letter or not?
To answer one part of your question ("is there any way I can make python not care about weather the input is capital letter or not?"): use some_string.lower():
>>> "foo".lower() == "foo"
True
>>> "FOO".lower() == "foo"
True
An this is to help you how you could improve the structure of your code:
import sys
from random import choice
WORDPAIRS = [('Humiliate', 'abasement'), ('Swelling', 'billowing')]
def ask():
pair = choice(WORDPAIRS)
while True:
answer = raw_input("%s: " % pair[0]).lower()
if answer == pair[1]:
print "well done!"
return
def main():
try:
while True:
ask()
except KeyboardInterrupt:
sys.exit(0)
if __name__ == "__main__":
main()
It works like that:
$ python lulu.py
Swelling: lol
Swelling: rofl
Swelling: billowing
well done!
Humiliate: rofl
Humiliate: Abasement
well done!
Swelling: BILLOWING
well done!
Humiliate: ^C
$
wooo = [word, word1]
while 1:
print(choice(wooo)())
But in any case it will print you None, cause both of your functions return nothing (None).
