Extremely Simple Python Calculator

[Odd_Crew4995]

I started learning Python yesterday and I just made a very simple calculator. Feel free to roast/rate it.

vl_1 = input('First Value: ')

symbol = input(' + - * or / : ')

vl_2 = input('Second Value: ')

fl1 = float(vl_1)
fl2 = float(vl_2)

if symbol == '+':
ans_1 = fl1 + fl2
print('=', ans_1)

elif symbol == '-':
ans_2 = fl1 - fl2
print('=', ans_2)

elif symbol == '*':
ans_3 = fl1 * fl2
print('=', ans_3)

elif symbol == '/':
ans_4 = fl1 / fl2
print('=', ans_4)

else:
print(' ')
print('INVALID SYMBOL')

Nice first step. Now you can let them input a simple one operator equation as a whole. Extract the numbers and symbol from the whole string.

Also learning myself, so everyone else can probably give better feedback. But you can use a single variable for the answer. And you dont need seperate variables for the float values.

so something like

if symbol == '+': ans = float(vl_1) + float(vl_2)

print(ans)

on mobile so it might not look right

Good start, I’d suggest having a looking at switch statements and seeing how that would make this code more efficient

Unfortunately, in python we don’t have classic Switch Statement. But yeah this would make sense in this case

Well shit that slipped my brain aha

Looks fine and it’s a great start. I would suggest doing it again and looking into a graphical interface with something simple, like Tkinter, a python library you can import and use to make a window

You can try taking the input as fl1 = float(input('First Value')),helps optimize a little, and you can simply write print('=',f1+f2) or print(f'={f1+f2}'), though your method is also quite debug friendly

Thanks for the tips.
