Solved: create simple calculator in python

The main problem related to creating a simple calculator in Python is that it can be difficult to write the code correctly. Python is a powerful language, but it can be difficult for beginners to understand and use. Additionally, coding errors can lead to incorrect results or unexpected behavior. Furthermore, writing code for more complex operations such as division or square roots may require additional knowledge of mathematics and algorithms. Finally, debugging the code can also be time consuming and challenging.

# This program adds two numbers 
num1 = float(input("Enter first number: ")) 
num2 = float(input("Enter second number: ")) 
# Adding the two numbers 
sum = num1 + num2 
# Display the sum 
print('The sum of {0} and {1} is {2}'.format(num1, num2, sum))

# Line 1: This program adds two numbers
# Line 2: num1 is assigned the value of a float input from the user
# Line 3: num2 is assigned the value of a float input from the user
# Line 5: The sum of num1 and num2 is calculated and stored in the variable sum
# Line 7: The sum of num1, num2, and sum are printed to the console using string formatting

Arithmetic operators in Python

Arithmetic operators are used to perform mathematical operations on numerical values (constants and variables). Python supports the following arithmetic operators:

– Addition (+): Adds two operands.
– Subtraction (-): Subtracts the second operand from the first.
– Multiplication (*): Multiplies two operands.
– Division (/): Divides the first operand by the second one.
– Modulus (%): Returns the remainder of dividing the first operand by the second one.
– Exponent (**): Raises a number to a power specified by another number.
– Floor Division (//): Divides and returns only the integer part of a division result, discarding any fractional part.

How do you make a simple calculator?

Making a simple calculator in Python is a great way to learn the basics of programming. Here’s how to do it:

1. Start by creating a function that will take two numbers as arguments and return the result of the calculation. For example, if you want to add two numbers, your function might look like this:
def add(num1, num2):
return num1 + num2
2. Create a loop that will allow the user to continue entering numbers until they enter ‘q’ or ‘quit’. This loop should also print out the result of each calculation as it goes along.
while True:
num1 = input(“Enter first number (or q to quit): “)

if num1 == ‘q’ or num1 == ‘quit’:

num2 = input(“Enter second number: “)

result = add(int(num1), int(num2))

print(“The result is”, result)
3. Finally, ask the user which operation they would like to perform and call the appropriate function based on their answer. For example:
operation = input(“What operation would you like to perform? (+, -, *, /): “)
if operation == “+”:
result = add(int(num1), int(num2))
elif operation == “-“:
    result = subtract(int(num1), int(num2))
    # etc…
