My Collections Of Python Projects by KlausMichaelson: 11:13pm On Jul 29
I am so glad that this journey have started yielding good fruits. My dream is to become an expert in Python one day and teach people how to write the language like Mosh Hamedani, Cs Dojo and Hamit Ranjit Grom ACADGILD

This is making it a month of Learning Python. Although I've seen some videos on python long before now but I didn't take it too serious. Already I have interest in Data Analysis but I still have some feelings towards Software development but that will be later on when I'm done learning Data Science and mastering all the tools in it.


So I'm going to be Posting some codes I write by myself everyday so as to keep the fire Burning. Please I will welcome any correction gladly.
Thanks be to God for the Holidays. This is ironically a bad year indeed.

Modified:
Please you can also give me a task or exercise to Work on. I'll be grateful.

So I spent the previous night thinking of writing a code that can accept input from a user and run different operations on it. The operations are limited to Addition, subtraction, Division, Multiplication, and Modulo. I came up with this after much thought.


number1 = int(input('what number? '))
number2 = int(input('what number? '))
calculation = input('what operation do you want? ')

def operation(num1,num2):
addition = num1 + num2
subtraction = num1 - num2
multiplication = num1 * num2
division = num1 / num2
modulo = num1 % num2
if calculation == 'addition':
return addition
elif calculation == 'subtraction':
return subtraction
elif calculation == 'multiplication':
return multiplication
elif calculation == "division":
return division
elif calculation == 'modulo':
return modulo


result = operation(number1, number2)
print(result)

Modified:
After taking Corrections from my Top Ogas in the House, I finally came up with a better code for the calculator.
Corrections are still welcomed.


number1 = int(input('Enter a number? '))
number2 = int(input('Enter another number? '))
calculation = input('addition, subtraction, multiplication, or division? ').lower()


def operation(num1, num2):
if calculation == 'addition':
return num1 + num2
elif calculation == 'subtraction':
return num1 - num2
elif calculation == 'multiplication':
return num1 * num2
elif calculation == "division":
try:
if num1 % num2 == 0:
return num1 / num2
else:
return num1/num2
except ZeroDivisionError:
print('cannot divide zero, enter a denominator other than zero')


result = operation(number1, number2)
print(result)

Sir any task at all. It could be to write a code to perform a particular function, I'll be very willing to do it.

Your program assumes you'll be the only user who knows the right keywords to enter in order to get the desired result.

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

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).

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

When writing codes, I always like to think like a typical user who'll love to experiment with any possible combinations.

I challenge you to solve the problems above and update your code....

Ha Sir grin

There is no problem Sir. I am grateful for you Assessment. Thank you.

*What tells the user the kind of operations my program can run?

Sir, I will give the updated code for it later today. Thank you very much sir. I really appreciate.

Alright..... You are welcome sir.

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

based on what ibromodzi has said, I could see ZeroDivisionError, TypeError and other Errors in this code,
When writing mostly inputation code, you need to validate user's input because if you fail to do so, your program will break as Python is a runtime language. Try to put it in 'try' and 'exception' block.. I wish you Goodluck in your learning.

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

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.
