Python Program to Add Two Numbers

by

To add two numbers in Python, you can use the + operator. Here’s an example of how to do this:

x = 1
y = 2
result = x + y
print(result)  # Output: 3

How do you add two numbers from user input in Python?

To add two numbers from user input in Python, you can use the input() function to get the numbers as strings from the user, and then use the int() function to convert the strings to integers. Here’s an example of how to do this:

x = int(input("Enter a number: "))
y = int(input("Enter another number: "))
result = x + y
print(result)

In this example, we use the input() function to get the two numbers as strings from the user, and then we use the int() function to convert the strings to integers. We store the integers in the x and y variables, and then we use the + operator to add x and y and store the result in the result variable. Finally, we print the result to the console.

Keep in mind that the input() function returns a string, even if the user enters a number. Therefore, you need to use the int() function to convert the string to an integer before you can add the numbers.

python program to add two numbers using class

To add two numbers using a class in Python, you can define a class with a method that takes two numbers as arguments and returns their sum. Here’s an example of how to do this:

class Adder:
    def add(self, x, y):
        return x + y

adder = Adder()
result = adder.add(1, 2)
print(result)  # Output: 3

In this example, we define the Adder class with an add() method that takes two arguments x and y and returns their sum. We create an instance of the Adder class called adder, and we use the add() method to add two numbers and store the result in the result variable. Finally, we print the result to the console.

python program to add two numbers without using + operator

To add two numbers in Python without using the + operator, you can use bitwise operators or arithmetic functions from the math module.

Here’s an example of how to add two numbers using bitwise operators:

def add(x, y):
    # Iterate until there is no carry
    while y != 0:
        # Carry now contains common set bits of x and y
        carry = x & y

        # Sum of bits of x and y where at least one of the bits is not set
        x = x ^ y

        # Carry is shifted by one so that adding it to x gives the required sum
        y = carry << 1

    return x

result = add(1, 2)
print(result)  # Output: 3

In this example, we define the add() function that takes two numbers as arguments and returns their sum. The function uses a loop to iterate until there is no carry, and it uses bitwise operators to compute the sum of the two numbers.

Here’s an example of how to add two numbers using the math module:

import math

def add(x, y):
    return math.fsum([x, y])

result = add(1, 2)
print(result)  # Output: 3

add two numbers without using + operator leetcode

LeetCode is a popular platform for practicing and improving your coding skills, including solving problems that involve adding two numbers without using the + operator. Here’s an example of how you might solve a problem like this on LeetCode:

class Solution:
    def add(self, a: int, b: int) -> int:
        # Iterate until there is no carry
        while b != 0:
            # Carry now contains common set bits of a and b
            carry = a & b

            # Sum of bits of a and b where at least one of the bits is not set
            a = a ^ b

            # Carry is shifted by one so that adding it to a gives the required sum
            b = carry << 1

        return a
