this script works in python2 but not in python3, the input question continues to be shown even if I put the correct answer :
correct = "no"
while correct == "no":
answer = input("15 x 17? ")
if answer == 15*17:
correct = "yes"
print 'good!' #for python2
else:
correct = "no"
how this can be solved both not using and using a function?
In Python 3 input returns a string (in Python 2 input evaluates the input) so answer == 15*17 will never be true unless you convert answer to an int or 12*17 to string.
Also, print "good" is not a valid Python 3 syntax as print is a function: print("good").
To make this work in both Py2.7 and Py3 there are couple of differences between the language versions - see What’s New In Python 3.0:
input() in py3 is equivalent to raw_input() in py2print is no longer a statement in py3 but a functionTo make this code work across both py2.7 and py3 you can do:
from __future__ import print_function
try:
input = raw_input
except NameError:
pass
while True:
answer = int(input("15 x 17? "))
if answer == 15*17:
print('good!')
break
