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.

Bit Manipulation Hacks | Brilliant Math & Science Wiki
In this wiki, we shall discuss a number of one liners that help us solve simple arithmetic problems in binary numbers. They are often found to be very useful (and quick) in larger programs. Because of the way numbers are represented in computers, these one liners are not only handy for the programmer but also very fast in execution. The Bitwise operators constitute the standard operators from ...

Concatenation of Consecutive Binary Numbers - docs.vultr.com
Immediately apply the modulo operation to keep the result manageable and within the limits of the data type. At the end of the loop, return total as the result. The solution efficiently handles both the binary concatenation and the modulo constraint by leveraging bitwise operations, ensuring performance is optimized even for larger values of ...

Python Operators: The Complete Guide – TheLinuxCode
Whether you‘re just starting out or looking to deepen your Python knowledge, you‘ll find valuable information here. What Are Python Operators? At their core, operators are special symbols that perform operations on variables and values (called operands). For example, in the expression 3 + 4, the + is the operator and 3 and 4 are the operands.

python - What does a star (asterisk) do in f-string? - Stack Overflow
This mirrors behaviour in f-strings and is likely because Python "the language" is inextricably tied to CPython "the implementation". Taking look at CPython 3.11's grammar shows that the rules pointed to by the OP don't exist in Grammar/python.gram. What exists instead is the following rule: fstring[expr_ty]: star_expressions
