Python Basic Arithmetic Operators – Comprehensive Guide with Examples
Arithmetic operators are fundamental in any programming language, including Python. They allow you to perform mathematical operations such as addition, subtraction, multiplication, division, and more. Understanding how these operators work and their subtle differences is key to writing effective and error-free code. 1. Addition (+)

Practice With Arithmetic Operators | Saylor Academy
4. Unary Arithmetic Operations. A unary mathematical expression consists of only one component or element, and in Python the plus and minus signs can be used as a single element paired with a value to return the value's identity (+), or change the sign of the value (-).Though not commonly used, the plus sign indicates the identity of the value.

python - How can I check if a string represents an int, without using ...
$ python --version Python 2.7.10 Both the two test cases I added (isInt_loop and isInt_digit) pass the exact same test cases (they both only accept unsigned integers), but I thought that people could be more clever with modifying the string implementation (isInt_loop) opposed to the built in isdigit() function, so I included it, even though there's a slight difference in execution time.

Write a program to reverse digits of a number - GeeksforGeeks
Time Complexity - O(log n) Space Complexity - O(1) . Note: The above program doesn't consider leading zeroes. For example, for 100 programs will print 1. If you want to print 001. Using String and Slicing in Python. The approach used is "Using Slicing".This technique involves converting the number into a string, then reversing that string by using slicing operations.

Arithmetic Operations on Images - OpenCV
Bitwise Operations. This includes the bitwise AND, OR, NOT, and XOR operations. They will be highly useful while extracting any part of the image (as we will see in coming chapters), defining and working with non-rectangular ROI's, and etc. Below we will see an example of how to change a particular region of an image.

Python NOT EQUAL Operator: Complete Guide – TheLinuxCode
This operator is the logical opposite of the equality operator (==). While == checks if values match, != verifies they differ. Historical Context: The Evolution of Python‘s NOT EQUAL Operator. Did you know that Python once had two different ways to express "not equal"? In Python‘s earlier versions (Python 2.x), you could use either != or <>:
