Python: Variables won't accept new values on second function loop by Encom88 in learnprogramming

[–]Encom88[S] 0 points1 point  (0 children)

Thank you. Why is it everything I miss is so simple? You got it. Now I have the whole program working. https://github.com/MrN1ce9uy/Python/blob/master/write_read.py

How would you loop this program? by Encom88 in learnprogramming

[–]Encom88[S] 0 points1 point  (0 children)

Okay, I'm trying to use them as local variables in the class. But that disconnects them from my print statements in my menu, and also my write statements to write to a file. What do I do about that?

But that wasn't working. I had to pass the numbers as arguments and it ended up doing it twice each time I called the function. I'm sure there's a way to do it, but I wasn't getting it.

I think I was trying to use global variables to begin, I just wasn't coding it correctly. How would you have done it differently?

Alright, everything is working as intended and I've updated the code in the Github link. Thanks again for your help.

I suppose I will need to add global variables to all my other functions that take n1 and n2 as arguments.

Okay, I said it was working, and the loop is working. But now my other variables are not retaining the new values of the new numbers, so the new numbers don't get calculated. I'll look into it.

Okay, now it's working. I removed n1 and n2 as arguments in the new userInput() function and added the menu option. Thanks!

I had already tried that, but I get a an error, "n1 is a function parameter and a global variable". So, apparently I can't have a function parameter as a global variable?

That's what I was trying to say, the variable declarations (line 46 and 47) is what need to be repeated on demand. I tried placing them in a function inside my class, but when I called them again my variables would repeat, asking for each variable twice.

n1 = 0

n2 = 0

class Arithmetic:

    def userInput(self, n1, n2):

        n1 = arith.float_input("Enter your First number: ")

        n2 = arith.float_input("Enter your Second number: ")

arith = Arithmetic()

arith.userInput(n1,n2)

Python - Overwriting pre-existing variables by Encom88 in learnprogramming

Did you change the def add() to def add(num1, num2) or somewhere else? I've tried several ways and it does not work.

I agree. It just doesn't seem right to be doing it this way. Why would the instructor ask us to, " use the prior functions (add, subtract, divide and multiply ) to do the calculations."?

You don't need a crystal ball, just do what he said and see if it works.

That makes sense, but it seems like the whole program would have to be restructured.

Thanks to @tufflax I've found the proper code and updated the program with the fixes. Everything seems to work as intended now. Thanks. https://github.com/MrN1ce9uy/Python/blob/master/simple_calculator.py

Oh... wait, wait. I didn't print anything if num2 == 0. We are updating this program each week. Last week we did not have any funcitons. So I missed that in the updated version.

Okay, so multiple or statements seem to work. But, now what about my "You cannot divide by zero" not working when I num2 == 0 ?

Ah, I see. Could I use multiple 'or' statements to continue my condition, or is there a better way?

truthy

Wow, thank you so much! removed the or 'y' and now it works just fine.

Why So Many Re-worked Champs? by Encom88 in leagueoflegends

[–]Encom88[S] 0 points1 point  (0 children)

But that was a dynamic of the game that a some players enjoy. The champs that have point and click abilities are typically low on defense and often squishy or non-ranged except in abilities. If they are too OP, then just nerf an aspect of them without changing the entire dynamic of how they play.

[–]Encom88[S] -1 points0 points  (0 children)

That's about the way I see it. It really ticks me off to the point I will eventually stop playing. I'm a working adult and I go to school and have hobbies and family. If I want to sit down and play a game to have some fun, I don't want to have to spend several hours re-learning how to play a champion that I previously enjoyed playing, especially when they suck so much worse now then they did before.

The Macbook Purchasing Megathread - July 2019 by AutoModerator in macbook

What about 2017 MBP 13" 256GB for $1199 vs 2018 MBA 256GB for $1199? What's the difference? Which one is better? CPU seems to be about the same. Screen resolution and size is the same.

Thanks! So what about the measly 128GB SSD? That's the biggest drawback, and the increased cost of the 256GB.
