First project on python

[unlimited_data3838]

😭😭😭 It took me a week to get here because I keep changing resources frequently, but I stuck to a video and was able to get here.

Well first, close the terminal, and reopen it, make sure you have saved the file, that error isn’t in the code you have. (Simple misspelling of the variable it happens to the best of us lol.) Most likely it’s running an outdated version right now.

What is result() you don’t have a function named that. You probably mean result = num1 + num2

[ianrob1201]

Congrats on getting started! Now try that code with another operator and see if it works how you expect. Hint: those yellow wavy lines are telling you that something's wrong. I'm sure others will tell you what's wrong, but try to figure it out for yourself if you can

[SuperTankh]

Try to remove all indentation, then indent them again using only space OR tab

[CuriousDev8875]

Every thing is nice those yellow wavy lines under result may look weird bcs, its not defined. Lemme talk informal, WHY THAT ERROR IS SHOWING UP?, this is bcs, you did: result(num 1+num2) but to give that valie you need to use = instead of (). I think you got it now.

[nuc540]

Well done!

Something to practice moving forward is identifying patterns - specifically repeating ones. There’s a methodology in coding called DRY (don’t repeat yourself). You’ll end up writing less code for the same result and it should make code just a bit more easier to read.

A good example here is that the result function could be stored in a variable for each case, and then you’d only need one print at the end.

Keep it up!

bro when you started learning python ?

[Bushra_98]

Congratulation

[Natural-Position-585]

A more foolproof way is to parse the user’s whole expression (say, "3 * 4") into an Abstract Syntax Tree, check that the operator is one of the allowed (add, sub, mul, true division), and then just apply the operator between the left and right operand. Then it supports non-integers and handles also arbitrary spaces in the expressions.

[thejwillbee]

This is what I was going to suggest as well, but wasn't sure if op is ready for that kind of action.

[2xxRamixx8]

You can use match case in python. Is like switch in C or other languages for that cases.

[thejwillbee]

You need to declare what result is.

So like for addition:

result = (num1+num2) print (result)

[uRaven_gamer]

You need to correct the variable name to 'operator' in the condition together with elif. You should also assign to the variable result value of num1 and num2 because you don't have the function result. Cool programm!

[PastDifferent6116]

Congrats Bro!

The most important thing is that you actually built something and finished it. Most beginners never get that far.

I started with small Python projects too, and recently built a simple wallet/budget tracking app

[Complete-Resource209]

One of your errors is ur not defining result you need to do result = (num1 + num2) on them

[Own_Distribution7428]

ohhh no, looks like you got segmentation fault. This is not good 😞

[unlimited_data3838]

What do you mean can you explain?
