How to Build a Simple Calculator in Python - Step by Step 1

a=float(input("Enter first number:"))
b=float(input("Enter second number:"))
print("Sum=",a+b)
print("Subtraction=",a-b)
print("Product=",a*b)
print("Division=",a/b)
print("Remainder=",a%b)
Isnt this better and easy?

Actually they also gave me as assignment

Is good😂

Hey how do i get rid of the errors it doesnt let me start the thing

Just wanna share my comments:

You can declare the numbers so you’ll have reusable function:

def get_nums():
x = float(input('Enter 1st number: '))
y = float(input('Enter 2nd number: '))
return x, y

and simply assign it to your operations function like this:

def sum(x, y):
return x + y

inside your loop you can do this instead:

x, y = get_nums()

so you don’t have to repeat it…

if operation == '1':
result = sum(x, y)

you can use fstring instead to make it simplified.
print(f'The Sum of {x} and {y} is {result}')


also put error handling on your division operation:

if y is equal to zero, you can print cannot divide by zero.

Overall, it' s really nice. Thanks for sharing your knowledge.

Highlh recommended

your teaching is brilliant please keep going

pls paste the code next time

1 line calculator: print(eval(input()))

Can you please share your WhatsApp number with me

I git an error at minus i needed to add an coma after the twxt xan someone explain?😅

Do you deal With Software While Implementing These Programs?🤯

This was such an amazing tutorial. Wonderful to follow and easy to understand! Keep up the great work.

This is a basic calculator for beginners and he did a good job, pretty weird of people to be flexing more complex ones in the comments that involve learning about float, it's for b.e.g.i.n.n.e.r.s float is what stops you sink to beginner.

Thanks again

Very helpful bro keep on going -_-

hi guys, i am trying to get to this programming thing, im looking for exercises for me to practice what i am learning, i just watch this video and i found a different way to code this calculator, and i would like to see if theres is something that could improve on this:

n1 = int(input('WHAT IS THE FIRST NUMBER? '))
n2 = int(input('WHAT IS THE SECOND NUMBER? '))
print ('SELECT AN OPERATION')
print('1. ADD')
print('2. SUBTRACT')
print('3. DIVIDE')
print('4. MULTIPLY')
OPERATION = input()
if OPERATION == '1':
RESULT = n1 + n2
elif OPERATION == '2':
RESULT = n1 - n2
elif OPERATION == '3':
RESULT = n1 / n2
elif OPERATION == '4':
RESULT = n1 * n2
else:
print('INVALID INPUT')

print(RESULT)

elif is red for me. did I do something wrong?

operation = input()
if operation == 1:

elif operation == 2:

elif operation == 3:

elif operation == 4:

I'm using visual code studio if you ask me

I think instead of using

operation = input()

if operation == “1”

You can use

operation = int(input()
If you want it to run without error instead of int use float() so if the user enters ‘1.5’ it’ll come back as invalid entry instead of error.
Also if you used int instead of float on num1 etc it will not read floats (numbers with a decimal)

Hii I have also upload one short on my channel which also includes creation of calculator program in python in script mode.
First time I have ever made a video related to python language .
please watch it once 🙏🙏
plzz plzzz

Bruh is just stuck with his own problems

I´ve got the same errors, thanks for the help :)

Thank you for this. I didn't know how to go about this but you just simplified it in 15 mins. Thank you so much

dude i think u need to learn the calculator first

im trying to build my own calculator in python but the + operator doesnt work properly, like im typing 1 as num1 and 3 as num2 but the program just prints out '13'

3 and 4 code are enterchange

Thank you, you made it sooooo simple❤❤😊

thank you

I just start to study Phyton this days but... at first, you dont need FIVE prints, right? I think if you just write with " " " should works; something like this:
print("""Select an operation to perfom:
1. Add
2. Subtract
3. Multiply
4. Divide
""")

hllo

Okay but where's the calculator u built tho ?

Nice
Thanks a lot

How to import fraction to this calculator?

a bit different.

while True:

print("addition 1:")
print("subtract 2:")
print("multiply 3:")
print("division 4:")

operation = input("Enter Number 1-4: ")

num1 = float(input("Enter Number: "))
num2 = float(input("Enter Number: "))

if operation == "1":
print(num1, "+", num2, "=", (num1+num2))
elif operation == "2":
print(num1, "+", num2, "=", (num1-num2))
elif operation == "3":
print(num1, "+", num2, "=", (num1*num2))
elif operation == "4":
print(num1, "+", num2, "=", (num1/num2))
else:
print("invalid submission")

thank you

Thank you so much ☺️

can you say me what i did wrong? i have 21 errors

rint("Select an operation to perform: ")
print("1. ADD")
print("2. SUBTRACT")
print("3. MULTIPLY")
print("4. DIVIDE")

operation = input()

if operation == "1":
num1 = input("Enter first number: ")
num2 = input("Enter second number: ")
print("The sum is " + str(int(num1) + (int(num2)))
elif operation == 2:
num1 = input("Enter first number: ")
num2 = input("Enter second number: ")
print("The sum is " + str(int(num1) - (int(num2))))
elif operation == 3:
num1 = input("Enter first number: ")
num2 = input("Enter second number: ")
print("The sum is " + str(int(num1) * (int(num2))))
elif operation == 4:
num1 = input("Enter first number: ")
num2 = input("Enter second number: ")
print("The sum is " + str(int(num1) / (int(num2))))
else:
print("Invalid Entry")

I keep getting invalid syntax anytime I run my code

This is really great. I like the way you intentionally made those mistakes to teach us what could cause any error.

You're a good teacher.

Bruh I need a calculator programm which can accept multiple inputs

Thank you so much!

Thanks brother. (Channel subscribed)

x = float(input("ENTER FIRST NUMBER :"))
opreater = input("enter operater (+,-,*,/) :")
y = float(input("ENTER SECOND NUMBER :"))

if opreater == "+":
print(x + y)
elif opreater == "-":
print(x - y)
elif opreater == "*":
print(x * y)
elif opreater == "/":
print(x / y)
else:
print("invalid syntex")

One simplest calculator 😃😃

Thanks!

i can code in 1 line
while True: print(f"ANS : {eval(input('> '))}")

And the sum shows "45"😂

Nice video, I did it
Btw how can I make it reusable

how can you fix this?
