A+ Study tool in python

[mruane]

I am preparing for my a+ exams, and am turning all of my notes into a test. I plan on doing this in python, of course. But, I am a little lost at what would be best. Should I create each question as a specific function, calling the next question function when i am done with that question? Or should I create one function to handle the questions, and functions for everything else? My plan for the format of the test is such:

present the question.
prompt the user to press enter when ready for answer
user presses enter
clear screen and begin again

this will go until there are no more questions left to ask, in which case the screen will clear and ask if you want to study again or quit.

thank you for your help.

If it is a something like a mutliple choice quiz, you can organize all the questions/answers into a list of tuples. Each tuple might have this order:
(question, answer1, answer2, answer3, answer4, answer_code)
Each of these tuples comes from a data file were each question looks like this:
question
answer1
answer2
answer3
answer4
answer_code
marker
next question
...

This arrangement allows you to random shuffle the tuples in the list, and pop properly answered question tuples out of the list. If you want to, you can encode the data file to keep folks from cheating openly.

A good activity instead of learning:)

I suppose you have some file with the questions...
So it can be loaded into a structure
questions=[question1, question2,....]

questions=["1","2","3"] # as test
qc=0 # actual question index
print("press enter for the next question q and enter to quit")
while True:
    print(questions[qc])
    key=raw_input()
    if key=="q": break
    print("\n"*45) # prints a lot of newline
    #next question
    qc+=1
    if qc==len(questions): qc=0 # return to the beginning

If this get boring, you can randomize the questions.

import random
#the same code
    #next question
    qc=random.randint(0,len(questions)-1)

I hope this helps.
Anyway, what is an a+ exam? I am not from the US.

i'm not sure how you would do it but i would recommend a class which you can then define for each question

Thanks for all of the advice guys, I actually put a a little of what each of you said into one method. An A+ exam is what you take to show that you have a good knowledge of how to troubleshoot computers, from a hardware and software perspective. If you pass your A+ exams, you become A+ certified. I am pretty sure you need to pass with a 95% or higher, which makes me nervous as if I fail, I have to pay to take the test again, which is like 186 USD each time.

Anyways, here is the start of my code, it just has 14 basic questions, but it gives an idea of where I am going with it. Maybe this code could help others who may be preparing for their A+ exams.

Main()

There will be miultiple sections, and I would like to learn how to make a multi file source code, so I could have the questions in one file. How would I work this, if the questions are in a file called questions.py, in the exact same path as the main file?

[scru]

Instead of all those print statements at the top, you can put

print "\n" * (blank lines you desire - 1)

[slate]

Yes. The clear function can be just print("\n"*55).

You can put the questions and answers in a file like:

Q
What is the Binary number system?
A
The Binary number system is a number system that uses only the numbers 1 and 0, where 1 represents "on",
  and 0 represents "off".
Q
Explain how the CPU uses the Binary number system.
A
The CPU takes input from input devices, such as the mouse or keyboard, and translates the data and instructions
    the input device sends to it into Binary form. The CPU then sends the Binary data and instructions to an output device,
    such as the monitor or the printer. In other words, if you type the word "Tom" into the cpu, the letters "t" "o" and "m"
    are converted into their binary form, consisting of the numbers 1 and 0. When you decide to print the file, the CPU sends
    the binary to the printer, which then converts the 1's and 0's back into the word "Tom".

etc...
So you dont have to type the apostrophes and the variable names.
Just take care, that before a question appears a Q in a single line, with the answer similar.
Let's name that sec1.txt.

We can load this file into a list containing question and answer pairs, some way:

def load_section(fname):
    section=[] #question and answer pairs
    f=open(fname)
    mode="q"
    q=""
    a=""
    for line in f:
        if line.strip()=='Q':
            if q and a: section.append((q,a))
            q=""
            a=""
            mode="q"
        elif line.strip()=='A':
            mode="a"
        else:
            if mode=="q":
                q+=line
            else:
                a+=line
    if q and a: section.append((q,a))    
    return section

So the code for sec_1 can be:

def sec_1():
    section=load_section("sec1.txt")
    clear()
    for q,a in section:
        print(q)
        raw_input("Press enter for answer")
        print(a)
        raw_input("Press enter for next question: ")  
        clear()
    clear()   
    print """This completes section 1. The other sections have not yet been written. Study these sections until you get them all right.

    press a to restart, or simply quit.
    """
    print
    x = raw_input("Press a to restart... ")
    if x == 'a':
        sec_1()

And the gues* functions go away....

EDIT: Woops, accidentaly just posted basically the same as the above. Sorry

[mruane]

No problem. I will definitely take a look at doing things that way, anything to shorted up my code, and make it more effective. The main goal is to quickly create a study partner to help me prepare for the exams. Thanks a lot, everyone, you have helped me out enormously!
