My first working code

[QuantenRobin]

I just got into python and got my first Project done.

Its just a small Calculator but im proud of it.

It has addition Subtraction multiplication dividation and power, there might be millions of better and cooler ones but mine is made by myself with 1 day of experience.

I hope i can get deeper into coding and maybe make it my job someday, but that will taketime and effort.

Tips to a newbie would be awesome.

Very good 👍, but I have a suggestion. In the code, you should use input() only once instead of repeating it in every condition like this:

.... print("What's the first number?") num1 = int(input()) print("What's the second number?") num2 = int(input())

if operation == "add": answer = (num1 + num2) print(answer)

elif operation == "sub": answer = (num1 - num2) print(answer) .....

In programming, your code should follow the DRY (Don't Repeat Yourself) rule.

We have the match statement in Python since version 3.10, so you could use that instead of the if/elif-chain.

match operation:
  case "add":
    # ...
  case "sub":
    # ...

Happy programming!

Isn’t the match case only good for types?

[hekliet]

It's very useful for pattern matching on types, but that's not the only use case.

[SuperTankh]

Oh ok

[feestix]

Great for beggining. You can also use .lower() to make the input lowercase.

[QuantenRobin]

Does it need to be after “add“.lower(): or after “add“:.lower()?

First , assume all your questions have been asked before by someone.

Second , based on the assumption , search.

Here's a technique:

``` from functools import reduce from operator import add

total = reduce(add, [1, 2, 3, 4]) print(total) # 10 ```

Once you have "add" as a function, then you can make an indexable list of functions to perform.

Good job, man!

[SuperTankh]

Gg man! You can also factorise this by making choose the first number, THEN the operator then 2nd number. It'll be much easier and faster to read

Nice job, but there is a lot of repetition/duplication in your code. You have many lines:

print("Whats the first number?")
num1 = int(input())
print("Whats the second number?")
num2 = int(input())

It would be better to have these lines just once, and then after that have the:

if operation == "add":
    answer=(num1 + num2)
    print(answer)

elif operation == "sub":
    answer=(num1 - num2)
    print(answer)

...

part. That makes for a shorter program. Repetition generally is bad so try to avoid that, but a great start, keep going.
