# Python: Find the XOR of two given strings interpreted as binary numbers

## Python Programming Puzzles: Exercise-25 with Solution

Write a Python program to find the XOR of two given strings interpreted as binary numbers.

Note: XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false. A way to remember XOR is "must have one or the other but not both". XOR can also be viewed as addition modulo 2. As a result, XOR gates are used to implement binary addition in computers.

Input: ['0001', '1011'] Output: 0b1010 Input: ['100011101100001', '100101100101110'] Output: 0b110001001111

**Pictorial Presentation:**

**Sample Solution-1:**

**Python Code:**

```

def test(nums):
return bin(int(nums[0],2) ^ int(nums[1],2))
nums = ["0001", "1011"]
print("Original strings:")
print(nums)
print("XOR of two said strings interpreted as binary numbers:")
print(test(nums))
nums = ["100011101100001", "100101100101110"]
print("\nOriginal strings:")
print(nums)
print("XOR of two said strings interpreted as binary numbers:")
print(test(nums))
```

Sample Output:

Original strings: ['0001', '1011'] XOR of two said strings interpreted as binary numbers: 0b1010 Original strings: ['100011101100001', '100101100101110'] XOR of two said strings interpreted as binary numbers: 0b110001001111

**Sample Solution-2:**

**Python Code:**

```
#License: https://bit.ly/3oLErEI
def test(nums):
a, b = nums
xor = int(a, 2) ^ int(b, 2)
return bin(xor)[2:].zfill(len(a))
nums = ["0001", "1011"]
print("Original strings:")
print(nums)
print("XOR of two said strings interpreted as binary numbers:")
print(test(nums))
nums = ["100011101100001", "100101100101110"]
print("\nOriginal strings:")
print(nums)
print("XOR of two said strings interpreted as binary numbers:")
print(test(nums))
```

Sample Output:

Original strings: ['0001', '1011'] XOR of two said strings interpreted as binary numbers: 1010 Original strings: ['100011101100001', '100101100101110'] XOR of two said strings interpreted as binary numbers: 000110001001111
