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

Sample Solution-1:
Python Code:
#License: https://bit.ly/3oLErEI
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

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
