python - Capture value from function -

i'm having trouble while trying store output of function below, i'm trying create maths quiz asks randomized basic math questions , gives ability answer questions while checking whether correct , wondering if able me out code or provide me insight need learn in order complete it.

here have far:

print ("hello maths quiz, name?") name = input() random import choice,randint  def rand_task1mathquiz():     a,b = randint(0,10),randint(0,10)     random_operations = choice(["+","-","/","*"])     print("{0} {1} {2}".format(a,random_operations,b))  if __name__ == "__main__":     x in range(10):     rand_task1mathquiz() 

the general pattern looking return statement. when want capture return value of function, typically, you'd assign function's result variable, assign static values variables, except () on right-hand side makes function call evaluted, rather reference function object.

notice how doing return values library functions randint(), choice(), range(), etc.

def rand_task1mathquiz():     a,b = randint(0,10),randint(0,10)     random_operations = choice(["+","-","/","*"])     return("{0} {1} {2}".format(a,random_operations,b))  if __name__ == "__main__":     x in range(10):         quiz = rand_task1mathquiz()         print quiz         # evaluate returned value somehow, compare user input 

the changed division of labor here worth noting -- function returns value, , caller prints it. useful function can run on own, no user interaction; input/output functionality should kept separate program logic far possible.

if want create list of questions, that's easy now, too:

questions = list() x in range(10):    questions.append(rand_task1mathquiz()) # questions 

or equivalently, less readably, using list comprehension:

questions = [rand_task1mathquiz() _ in range(10)] 

a further improvement might have function return both question , answer; makes sense keep them both close in program code.

def rand_task():     a,b = randint(0,10), randint(0, 10)     ops = {'+': int.__add__, '-': int.__sub__,         '/': int.__truediv__, '*': int.__mul__}     random_operation = choice(list(ops.keys()))     # should still guard against op='/' b==0     return ops[random_operation](a, b), \         '{0} {1} {2}'.format(a, random_operation, b) 

... though using __add__ , friends tricky understand yet. beats eval in terms of security, perhaps should try it.
