hi guys... about a week ago. fleshbone shared with us his first CBT code.. in python 2.7

so i re-wrote the code in python 3...

here it is...

wasnt good as the first though..

pls its open to criticism.. thanks

This is impressive boss (phililp)


Am not on a pc now, I would go through it better later in the day when am back home. Kudos.


antieverything should see this. Am sure he has a lot to share too.

Pls contact me in private

Pls contact me in private

Sorry sir, I don't know how to send private messages here.

Philip, i ran the codes it was pretty clean. Except for some typos. it's okay .

But really, as for me i don't think writing a code for an exam and the [/b]questions seen to be contained in the codes[b] is "fresh". i will rather create a text_file on my PC and the Program access the text_file for the question and answer, i feel its neater and more okay. i'll try and work on this too + i think am interested in the GUI.

fleshbone , thanks for stirring something up.

Why are you guys reinventing the wheel? Loads of Open Source CBT software exist to do what you are trying to do. I'd like to know what new addition you are making to already existing solutions?

We are actually all learning. Would love to see ur version of the program anyway so we can all get beTter. Thank to you too.

Am currently reading a book about GUI Using Tkinter module.

I would come up with something soon.

sorry but i think its important we start from somwhere... u dont expect a beginner to create new kinda AI.

we learning bro

thanks for the hint....

about the GUI... u working on it too??

pls boss.... what the name of the book... is it E-book.

been using videos from thenewbostom.. need a book too

maybe you call it re-inventing the wheel... Maybe you are way ahead of us in this. But i believe guys here in this thread aren't really claiming any professionalism in app development. And i also believe that we all grow by going from known to unknown.... and every person that thought outside the box first of all knows what's within the box and saw it insufficiency...


Reviewing open source codes are really cool in fact i do that on GIThub but the truth is if i don't practice some certain things i will i know that i know them. No one here is satisfied with this level we all want to improve, at least for me and doing what has been done is a way of learning how it is been done... it's not about what you did now but the understanding is what matters. Then when i review some code, i can be like "oh, so this stuff can be done like this" or be like "i think if this stuff is done this way it will help reduce resources consumption... or be like "wow, am just seeing this". Whichever way it goes, the contribution towards or knowledge added is built on something you'd learnt earlier... i also want to bring new ideas into existing ones but how will i do that if i don't know hot the existing one works. Threads like this is just for simple stunt pulling. I believe Albert Einstein would have solved questions USING the UNDERSTANDING of Newton's equation until he reasoned that Newton might actually be wrong.

Or should we now tag new guys in the "Hello World level" as re-inventing the wheel? No!...The sole-aim of this is to LEARN.

I know you are trying to stir up an awakening in us to look more into what we can give and add to existing ideas and not to be complacent but it looked more like an attack on the learning process.

phililp:
thanks for the hint....

about the GUI... u working on it too??

Yea i will be working on it this night.. And see what's up in the morrow.

Yh, i have written my version last night. Also, I will try and work on the GUI this night.. But i don't know how to post it like phililp did.. I don't what the indentation compromised. Phililp, how did you post yours?

use this tag

 paste your code here 

from time import *
import random

Better to write
from time import whatever_you're_actually_going_to_use_from_the_time_module
from random import whatever_you're_actually_going_to_use_from_the_random_module


Hope you don't mind if I ask what this line
time.sleep(2)
is doing in the student name class


Re-write the last two lines as

def main():
if __name__=="__main__":
name()
subject_selector

The above are more about best practices than about code correctness though.


Your questions is a dictionary. How are you indexing into it like a list?

I'm trying to understand what you intend to do in that for loop. I'll post my code for you to take a look

fleshbone:
use this tag

 paste your code here 

I guess you have a github account. Just post it on github and provide a link. Its the best way.

Hmmmm. I've looked at your code a little closer.

Your for loop has some problems

I'll try and do a line by line comment and post a link here:

Meanwhile check out this chapter of ATBS https://automatetheboringstuff.com/chapter8/

Its free.

Also, I just created a github repo. From time to time I'll be using it for stuff like this here on nairaland.
You can see all codes here

https://github.com/Parousiaic/nairaland_programming

TheLordIsGr8:

Sorry I didn't expect it to show that way.

Here is an html tag for code '<code>paste your code in here</code>'.

But instead of '<' use '['. And for '>', Use ']'.

Hope you don't mind if I ask what this line
time.sleep(2)
is doing in the student name class


Re-write the last two lines as

def main():
if __name__=="__main__":
name()
subject_selector

The above are more about best practices than about code correctness though.


Your questions is a dictionary. How are you indexing into it like a list?

I'm trying to understand what you intend to do in that for loop. I'll post my code for you to take a look

thanks sir; 'll keep these corrections in mind...

but what exactly does the

if _name_ == _main_ do?

kayoph:
Philip, i ran the codes it was pretty clean. Except for some typos. it's okay .

But really, as for me i don't think writing a code for an exam and the [/b]questions seen to be contained in the codes[b] is "fresh". i will rather create a text_file on my PC and the Program access the text_file for the question and answer, i feel its neater and more okay. i'll try and work on this too + i think am interested in the GUI.

fleshbone , thanks for stirring something up.

thanks sir! but the thing is i really dunno how to do the text_file thing..

can u just give me a crash course one it?? pls... just a little light lemme build on

kayoph:
Yh, i have written my version last night. Also, I will try and work on the GUI this night.. But i don't know how to post it like phililp did.. I don't what the indentation compromised. Phililp, how did you post yours?

dunno what i did O ... just copied from my IDE and pasted.. then later modified.

kayoph:
Yea i will be working on it this night.. And see what's up in the morrow.

YAS!!! i remember now.... this was what happened.

i first wrote the five first line of the post then summited(forgot to past the code).. then came back and modified and pasted the code... thats it

I'm a sort of beginning pythonista myself. But I believe I've been digging a bit longer than you. So I'm learning as well.
So in this jupyter notebook I try to explain the whole thing to myself. You can view it here

Guys, this the link for my version:

Man, leave the "Sir" thing. you can refer to me as simply "kayoph"... Check out the code on the hub first and see if you grab anything concerning the text_file thing.

thanks fleshbone

This is the screenshot for the cbt.txt file:

nice one!

thanks Man! i now understand everything about the __name__ == __main

your explanation nearly confused me though


now working on the txt file...

thanks again!

airsaylongcon:
Why are you guys reinventing the wheel? Loads of Open Source CBT software exist to do what you are trying to do. I'd like to know what new addition you are making to already existing solutions?

I try pointing this out to guys I see here on nairaland...on the long run, they see me as a hater

Well, my abstract thinking have blessed me with many fresh original ideas I can't wait to unleash...

Sure. It takes some time to wrap one's head around some things. But with patience you'll get there. I keep updating the file as I realize better ways to explain it.

Hello Kay. I wish to make an observation about your naming scheme.

You created a repository. The name of the repo shouldn't have any extensions. It looks like the repo is a python file which is not the case. The name of your repo should be the project name. I will think something like "Nairaland CBT." The exam part is redundant in so far as T stands for Test. Unless you have something else in mind.

For your code file which you called "The main code", you should give the file a good descriptive name and add an extension. Remember, no spaces in file names. Don't even use dashes. Underscores are your best friend.
