How to make items on a list show, with input from the user

Question

Is it possible to make items on a list appear one at a time but it has to wait for the user to input, before the program shows the next item?

here is my code:

import os

correct=0
incorrect=0
missed_questions=[]
incorrect_questions=[]

def question1(question_name,question):
    print(question_name)
    print(question)
    answer=int(input())
    if answer == 4:
        os.system('cls')
        global correct
        correct=correct+1
    elif answer != 4:
        global incorrect
        incorrect=incorrect+1
        global missed_questions
        missed_questions.append(question_name)
        global incorrect_questions
        incorrect_questions.append(question)
def question2(question_name,question):
    print(question_name)
    print(question)
    answer=int(input())
    if answer == 1:
        os.system('cls')
        global correct
        correct=correct+1
    elif answer != 1:
        global incorrect
        incorrect=incorrect+1
        global missed_questions
        missed_questions.append(question_name)
        global incorrect_questions
        incorrect_questions.append(question)

print('****** Welceome to the Online Maths Test ********')
print()
print()
print()
print()
print()
print()
print()
os.system("PAUSE")
quiz()
for q in missed_questions:
    print('Incorrect questions were: ', q)
    print('')
    print('')
    print('')
re_take()

i attempted the list on the re-take funcation.

i tired it but i cant find the right coding. if you can show me in a example that would be great. — Jamal, Apr 18 '16 at 19:54
i am creating a quiz with 10 questions and i want to add a feature at the end of the quiz where it asks the user to re try the question they got incorretly. — Jamal, Apr 18 '16 at 19:56
post what you have tried and what problems you ran into. It's quite a simple problem but this isnt a code writing service — nathan.medz, Apr 18 '16 at 19:56

See this:

l = [1, 2, 3]  # Your list
for i in l:
 input = raw_input("Show message") # Get input before
 print "current list item ", i     # displaying list item

Thank you for the response. – Jamal Apr 18 '16 at 20:00
Can someone explain the downvote? This is just a code snippet to illustrate the approach. – trans1st0r Apr 18 '16 at 20:01
I think he meant that all answers will be displayed, and only then the raw_input part – Yotam Salmon Apr 18 '16 at 20:03
well, he says that he wants to wait for user input before showing next item. – trans1st0r Apr 18 '16 at 20:04
yes, i would like to how to make a code like that. – Jamal Apr 18 '16 at 20:06

You can do that:

a = ["first answer", "second answer", "last answer"]
answer = raw_input("\n".join([chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))]))

Edit (for Python 3):

a = ["first answer", "second answer", "last answer"]
answer = input("\n".join([chr(x + ord('A')) + ") " + a[x] for x in range(len(a))]))

Explanation:

for x in xrange(len(a))

Iterates through the indexes of the list a

chr(x + ord('A'))

Converts the indexes into letters - 0->A, 1->B, 2->C

chr(x + ord('A')) + ") " + a[x]

Formats a string containing the answer letter and the answer itself.

A) first answer
B) second answer
C) last answer

Each one seperatedly.

[chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))]

Generates a list of formatted answer strings (iterates through a, formats a string, and dumps it into a list.
Now,

"\n".join[chr(x + ord('A')) + ") " + a[x] for x in xrange(len(a))]

Takes that list, and concatenates it with \ns. Now everything left is to print it and wait for an answer.
Hope I helped.

Which python version are you using? – Jamal Apr 18 '16 at 20:24
2.7.3 What version are you using? (I can optimize the solution for your version) – Yotam Salmon Apr 18 '16 at 20:25
3.5.1 when i saw raw input i didnt recognoise it – Jamal Apr 18 '16 at 20:26
So raw_input() should be change to input() – Yotam Salmon Apr 18 '16 at 20:29
I have eddited my answer to match also Python 3. If it helped you, please upvote it or tick it as the correct answer. – Yotam Salmon Apr 18 '16 at 20:30
By the way, when you used the For loop, i noticed you added x to range. Was that a typo? – Jamal Apr 18 '16 at 20:36
No, indeed. The range method generates a list of numbers (example: [0, 1, 2, 3, 4, 5]. The xrange method just simulates that list without really creating it in the memory. This allows us to iterate through huge lists without using a lot of memory. In this particular case, you can use both range and xrange, but in other cases xrange is neccesarry. FYI: http://stackoverflow.com/questions/94935/what-is-the-difference-between-range-and-xrange-functions-in-python-2-x. In Python 3, AFAIK, they dropped range, and changed Python 2's xrange to Python 3's range. So in Python 3 it's range. – Yotam Salmon Apr 18 '16 at 20:48
'range() now behaves like xrange() used to behave, except it works with values of arbitrary size' i read this in the python website. They introduced this after the 3.5 version. That is why my IDLE didn't register xrange. – Jamal Apr 18 '16 at 20:55
Yea, Forgive me for the lack of knowledge with Python 3.x, I just really like 2.7 and updating is currently not an option... – Yotam Salmon Apr 18 '16 at 20:58
No problem man, i appreciate you helping me. – Jamal Apr 18 '16 at 20:59
