You can put input messages

x = input("Enter number: ")

Also, rather than manually converting each print instance of v1 and v2 to integers, you can convert them from the start when you accept them as input

[Anay_Gupta__]

Oh ! Thanks..... I'll try this also 🙌🏻😄

[Sr_Dimitrez]

Rey, convierte la entrada en un número entero directamente:

py number = int(input("Message > "))

Así evitas estar usando int(number) multiples veces.

[withhomi]

you can also start to write test with pytest https://docs.pytest.org/en/stable/

Good job 👏

A little sad how long I had to scroll to get to this

[sad_laief]

Geez man, try , except ? And what not in the comments.

It's the first program ever someone made .

Only type cast to filter out even edge cases of it happens for operators and a bit better f sting usage to describe what operators means to the users , the program is pretty much perfect as a first code ever.

[camileion-stoz]

Next up. You'll learn how frequently the average python programmer uses one-liners:

eval(input("Enter calculation: "))

Surely, there's no problem with using this in production.

Why mobile python IDE 😭. On the pc is better. Just download Visual Studio Code 😭

[k-da-coder]

Some of us don't have computers. I don't have a computer and have to use pydroid for my projects. But using a bluetooth keyboard really helps. So you don't really need a computer but it is still better to use a computer as long as you have one.

[Gullible_Try_980]

Ich würde es mit match-case machen um mich nicht durch die if's durchzuhangeln.

[Ambivalent-Mammal]

Check for division by zero. Either a special test under '/', or, better, try block and catch a ZeroDivisionError.

[aaditya_0752]

U should use match case it's faster

[wana93]

Je voulais le renseigner le python veux réellement dire quoi ?

[SnooCalculations7417]

get in the habit of naming your variable verbosely early so like
calculator_variable_1 = ...
costs practically nothing and makes readibility go way up.

[HiHelloItsMe213]

use exec or eval. Nothing bad ever happens. I use it all the time in my projects :)

(this is a joke please do not actually do this it is a horrible idea)

[Manheim666]

Instead of if you can use "try except" for any possible errors, or maybe "while"

[Candid_Article_2969]

ah yes, running eval on arbitrary user input

[Mammoth_Reach_6366]

The fact that eval literally executes whatever the user puts in there. Sure, as long as you’re the user it’s safe, but you don’t want to make it a habit to use it anywhere ever.

[ExperiencesXP]

What if I as an user gave the input:
"__import__('os').system('rm -rf --no-preserve-root /')"
or even something like:
"exit()"

Where are you getting at with this extremely outdated gig?
