Do you have link which I can use to to download the videos from?

No sir I don't. But why not try YouTube videos??
Mosh Hamedani on YouTube did a 6hr+ video on python. You'll love it!

Excuse me, I'm out of the topic. Does anybody here know how long it takes for the openWeather API keys to be activated. They emailed me that it will take a couple of hours and it has been a day now
Pls look for another weather api to use openWeather always throws in a cors error and no-cors can't even fix it.
Check out darksky api

Good evening Sir

Your question:
What tells the user the kind of operations your program is capable of performing?

My Answer:
Calculation = input('addition, subtraction, multiplication, division, or modulo? ')

Your Question:
What happens if the user does not enter the operations to be performed correctly as used in the program? Like Addition instead of addition (issue of cases).

My Answer:
I use .lower if I want any input to be in lower case i.e
Calculation = input('addition, subtraction, multiplication, division, or modulo? ').lower

Your Question:
What happens if the user tries to divide a number by zero?

My Answer:
You use try except ZeroDivisionError or ValueError

But Sir I don't know where to to put in this try, except block in my program sad

The reason why I am yet to update my new code after about an hour now is because I don't know the position where the try..... except ZeroDivisionError and except ValueError block comes in. Please help me sir.

Thank you





def operation():

'''
You start the top of the program with while loop
purpose: the program executes once and then checks if all condition are satisfied
if no error is encounterd, the program perform its function and end
else the while loop runs again and agin untill no error is encountered

Let me know if there's anything you don't get
'''
while True:
x = int(input('Enter a number '))
y = int(input('Enter another number '))
calculation = input(f"'You can eiher enter addition, subtraction, multiplication"
f" or division to perform an operation'"wink.lower()

if calculation == 'addition':
print(f"result is {x+y}"wink

elif calculation == 'subtraction':
print(f"result is {x-y}"wink

elif calculation == 'multiplication':
print(f"result is {x*y}"wink

elif calculation == 'division':
'''
this is where exception handling goes
'''
try:
'''
the next block first checks if the result has no remainder (modulus) i.e an integer
if the number has no remainder, you get the result of the division printed
else you print the result along with the modulus
I prefer to include this here instead of having it as a seperate calculation
'''
if x % y == 0:
print(f"result is {x/y}"wink
else:
print(f"result is {x/y} remainder {x%y}"wink

'''
You break the while loop if the above condtions run with no error
else, the user is forced to re enter the value again i.e the loop starts all over
'''
break

except ZeroDivisionError:
print ("can not divide by zero, enter a denominator other than zero"wink
except ValueError:
print ("Invalid parameter"wink
operation() #just call the function

Sir I am very sorry to not have brought this to your notice. I really feel Happy having you around Sir. I have to force myself up this early morning to rewrite my code especially the area you brought in the try.... except ZeroDivisionError. I have tried using it in my code before now, but I just didn't know where to bring it in. Thanks a lot for the clarification.

Although I didn't use while loop, I was able to still use the if and elif. Sir your corrections are welcomed gladly.
Sir check my updated Post to see my new code

You may add an extra bonus by implementing your solution in OOP (not necessary though).

I am through for the day as it is very late here, I would have shown you the code but you have to change the logic if you want to use the try and exept block.
I recommend while loop, if it's true, then it will keep requesting for the user's input if there's an error until you put a condition to meet.
Read more on while loop, try and exeption. As a beginner, try to fix things on your own, when you reach that point you feel you are lost then you can Google or use stackoverflow. Goodnight.

Sir I have updated my Code. Thank you very much.

Wow. I appreciate your time and response Sir. Thank you very much.

Sir why didn't you try using
>>>try:

>>>except ZeroDivisionError:
to avoid ZeroDivisionError when zero is used as the denominator? or did your code checkmate it?? Pls go through my own updated code.

He's actually taken that into cognizance, albeit not in a Pythonic way..

You guys should try to work on real life problems. You can use the site someone suggested above.

Alright that's cool.

Sir pls don't mind me. I'll still check out that website. It's just that I have diverted my attention to Django at the moment... This whole thing is really not easy.
Re: My Collections Of Python Projects by KlausMichaelson: 8:43pm On Jul 31
Good evening my Pros please I have a Target at the moment. I don't know if anyone has ever considered the exercise before. It goes this way;

I want to write a code that will predict a time table or roster for lesson teachers in a senior secondary school.
Each teacher must have two subjects to teach. They must also appear at least 2times/perioy in a week and the period they are to teach must not clash with their second subject in any of the lesson period. The Program should enable me prepare a time table for all the teachers' lesson period.


My head is aching me cos I've been thinking about it for quite a while now.

Exactly, I had the feeling it's beyond the use of Python only. Machine learning is coming to mind.

Honestly this stuffs aren't too smooth like I thought. I went through machine learning tutorial yesterday, I was introduced to Sci-kit learn and some decision trees and algorithms. I'm just stuck at so many things right now(numpy, powerbi , Django) . But there is no problem.

I have no choice than to keep learning. Thank you sir.

ML for this task? Nope
Data structure and algorithm ain't the same as data science.
One last thing I'll say is that you should have your goal(s) defined. You can't learn everything at a time.

Challenge for you

It is possible to name the days 0 thru 6 where day 0 is Sunday and day 6 is Saturday. If you go on a wonderful holiday leaving on day number 3 (a Wednesday) and you return home after 10 nights you would return home on a Saturday (day 6). Write a general version of the program which asks for the starting day number, and the length of your stay, and it will tell you the number of day of the week you will return on.

Note: do not use any calendar module
