Ive learned C++ from your videos, Python is just so easy

[@currytut455]

what happens when you divide 1/0 or some x/0 because i have a major problem in doing the operations when its some number over zero (x/0), can you help me please or maybe someone else in the comment sections who maybe come across such a problem and was able to debug or solve the problem it would be very helpful to me.

Explain your issue again pls

[@currytut455]

​@@Cat-memes_official625When I attempt the operation 1/0 using the Python calculator code, it returns an error message. I struggled to debug this message and wanted the code to print "Undefined" for x/0 division operations rather than an error message. That's all I wanted.

Thanks cool vid helped me out alot 😃

[@runaan7382]

what are f strings used for? i see them all the time but i dont understand what makes them different from a normal print

[@demon3769]

in f strings we can insert any variable that we have created without any errors and can perform manipulations easily like age=12 if we use print function like print(f"the stan is {age} years old) in this above line at that age placed in curly bracket will show number 12 if print function is executed

what can i do if i want once the operation is made to ask again for the operation?

[@vaggelisgeorgiou2491]

I just picked up coding and I absolutely love your tutorials, thank you Bro for all the effort you put in!! I have a question. Couldn't we have made only one print( ) in the end of all the if elif else? Something like print(f" {num1} {operator} {num2} = {result} ") Wouldn't that work instead of having many print( ) statements for all the steps?

At the end you said that unfortunately we still have to type in the numbers, but can't we put the else statement as an if statement and then put an else statement that does nothing?

i wrote this code: operator = input("Enter an operator (+ - * /): ") num1 = float(input("Enter the 1st number: ")) num2 = float(input("Enter the 2nd number: ")) valid_operators = ["+", "-", "*", "/"] if operator not in valid_operators: print(f"{operator} is not a valid operator") elif operator == "+": result = num1 + num2 print(round(result, 3)) elif operator == "-": result = num1 - num2 print(round(result, 3)) elif operator == "*": result = num1 * num2 print(round(result, 3)) elif operator == "/": result = num1 / num2 print(round(result, 3)) else: print("") i don't get why you still have to write the numbers before printing the "operator is not a valid operator"

Because 'return' stores the output but does not display on output screen Only 'print' displays the value on output screen Return is useful when we only want to store value and not display it I hope u understood... 😊
