For some reason my code won't return False EVER and I cant figure it out?
I think the issue is with how my between
function is written but it makes sense to me. Also I am struggling to get my restart function to work. If somebody could help me with those 2 areas I would be extremely grateful.
def between(a,b,c):
if a>b and b<c:
Rnum =True
else:
Rnum=False
def main(): #main function need in all programs for automated testing
print ("This program will ask the user for 3 numbers and determine if
the second number lies betweenthe first and the third")
print()
while True:
numone=input('Please enter the first number - the low number:')
if numone.isdigit():
numone=int(numone)
break
else:
print('Invalid response. Please enter a whole number.')
while True:
numtwo=input('Please enter the second number - the test number: ')
if numtwo.isdigit():
numtwo=int(numtwo)
break
else:
print('Invalid response. Please enter a whole number.')
while True:
numthree=input('Please enter the third number - the high number:')
if numthree.isdigit():
numthree=int(numthree)
break
else:
print('Invalid response. Please enter a whole number.')
sprint()
number =between(numone,numtwo,numthree)
print('The statement ' + str(numone) + ' lies between ' + str(numtwo) + ' and ' + str(numthree) + ' is True.'"\n")
#Restart question
while True:
restart = input('Would you like to play again (Y/N)? ')
if restart == 'Y' or restart == 'y':
print('Restarting!' + ('\n' * 2))
break
if restart == 'N' or restart == 'n':
print('Thank you for playing.' + ('\n' *2))
break
else:
print("Invalid response. Please answer with a 'Y' or 'N'")
if restart == 'N' or restart == 'n':
break
else:
continue
if __name__ == '__main__' :
main() #excucte main function
You have small mistake, either in the problem definition or in the example code. Anyways if you modify it a bit:
def between(a,b,c): if b>a and b<c: return 'True'
else: return 'False'
print('The statement ' + str(numtwo) + ' lies between '
+ str(numone) + ' and ' + str(numthree) + ' is ' +
between(a,b,c) +"\n")
The logic of your between
function was slightly wrong (I've rename the variables to make it slightly clearer). In addition, you were not returning
the value of the function so it was basically doing nothing. You were also always printing "True".
I have modified your code to return
the result of the between
function. I have made the result of this function a variable called true_or_false
which is then printed at the end of each game.
In order to get your code to loop, all you need is another while
loop which you can break out of if the user does not want to continue.
def between(low,test,high):
if low < test < high:
return True
else:
return False
def main(): #main function need in all programs for automated testing
print ("This program will ask the user for 3 numbers and determine if\nthe second number lies betweenthe first and the third")
while True:
while True:
numone=input('\nPlease enter the first number - the low number:')
if numone.isdigit():
numone=int(numone)
break
else:
print('Invalid response. Please enter a whole number.')
while True:
numtwo=input('Please enter the second number - the test number: ')
if numtwo.isdigit():
numtwo=int(numtwo)
break
else:
print('Invalid response. Please enter a whole number.')
while True:
numthree=input('Please enter the third number - the high number:')
if numthree.isdigit():
numthree=int(numthree)
break
else:
print('Invalid response. Please enter a whole number.')
true_or_false =between(numone,numtwo,numthree)
print('The statement ' + str(numtwo) + ' lies between ' + str(numone) + ' and ' + str(numthree) + ' is ' + str(true_or_false) + "\n")
restart = ""
while restart.upper() != "Y":
restart = input('Would you like to play again (Y/N)? ')
if restart.upper() == "Y":
print('Restarting!')
elif restart.upper() == "N":
print ('Thank you for playing.')
sys.exit()
else:
print("Invalid response. Please answer with a 'Y' or 'N'")
if __name__ == '__main__' :
main() #excucte main function
