计时器，日期和脚本。

Question

So i'm doing a project and have wanted to add some extra features to make it unique.

How do I make it output a timer sort of thing where it would say "It took you (minutes:seconds) to answer this question" after each question and then a overall timer at the end of the exam (Script). Also, how would I add a date on when the exam was taken. What else could i add to make this more unique and users actually interested in doing this. I have simple input features where it asks for their name, class name and then adds up the total score and outputs into a file, named after the class name using 'with' and 'open' commands.

OPERATIONS = [             # this is stating what the operations are.
    (operator.add, "+"),
    (operator.mul, "*"),
    (operator.sub, "-")
    ]
for _ in range(10):
    num1 = random.randint(1,10)#This will randomly select num1 & num2 to be from 1-10
    num2 = random.randint(1,10)
    op, symbol = random.choice(OPERATIONS) #this will make the symbol equal to the operations and randomly select it by using .choice
    print("What is", num1, symbol, num2,"?")
    if get_int_input() == op(num1, num2):#this will check if the input is true or false by using ValueError if its false.
        print("Well done",name,"you got it correct!")
        score += 1
    else:
        print("Incorrect, better luck next time!")

You can keep state of when you asked the question by using datetime.now() and checking how long it took with datetime.now() - prior time like below. Getting the date is pretty easy as well, datetime.strftime("DD-MM-YYYY") but what I had wrote below has the added benefit of keeping the day as well.

OPERATIONS = [             # this is stating what the operations are.
    (operator.add, "+"),
    (operator.mul, "*"),
    (operator.sub, "-")
    ]
test_begin = datetime.now()
for _ in range(10):
    num1 = random.randint(1,10)#This will randomly select num1 & num2 to be from 1-10
    num2 = random.randint(1,10)
    op, symbol = random.choice(OPERATIONS) #this will make the symbol equal to the operations and randomly select it by using .choice
    start = datetime.now()
    print("What is", num1, symbol, num2,"?")
    if get_int_input() == op(num1, num2):#this will check if the input is true or false by using ValueError if its false.
        print("Well done",name,"you got it correct!")
        score += 1
    else:
        print("Incorrect, better luck next time!")
    time_taken = datetime.now() - start

test_length = datetime.now() - test_begin
print(test_length.strftime("DD-MM-YYYY"))

What you want to do is make use of time from the time module.

You want one timer that starts when your entire application runs, and then you want a question timer that you reset after every question.

Here is an example. I leave the refactoring of injecting in to your code up to you.

Make use of a dictionary to store your your results so you can easily look them up later. And then you can just output your dictionary for your results.

from time import time

exam_time = {}

exam_timer_start = time()
for i in range(1, 10):
    question_timer_start = time()
    answer = input('question')
    exam_time["question_{}".format(i)] = time() - question_timer_start
    question_timer_end = time() - question_timer_start
    print("That question took you {}s to complete".format(question_timer_end))
exam_time["total_exam"] = question_timer_end

print(exam_time)
