python - How to get the relative complement of a boolean numpy array ...

I'm trying to retrieve an array that has the same length (5) and contains True in each position where v1==True AND v2==False. That would be: Is there a quick way in numpy, something like logical_not() but considering v1 as the reference and v2 as the query? You just need to use the right bitwise operators:

Python Booleans: Use Truth Values in Your Code – Real Python

Because True is equal to 1 and False is equal to 0, adding Booleans together is a quick way to count the number of True values. This can come in handy when you need to count the number of items that satisfy a condition.

Some Useful Things About Tilde Operator in Python

In this article, we will learn about a tilde operator in python. Tilde operator is one of the types in Bitwise operator. ~ is a symbol that denotes a tilde operator in python. Look at this symbol. It is something different from others. We are not using these symbols the most. This operator is also known as complement operator or NOT operator.

Tilde (~) Operator in Python – Be on the Right Side of Change - Finxter

Python’s Tilde ~n operator is the bitwise negation operator: it takes the number n as binary number and “flips” all bits 0 to 1 and 1 to 0 to obtain the complement binary number. For example, the tilde operation ~1 becomes 0 and ~0 becomes 1 and ~101 becomes 010. But be careful because the integer value 0 is represented by many bits.

Two's Complement binary for Negative Integers: Negative numbers are written with a leading one instead of a leading zero. So if you are using only 8 bits for your two's complement numbers, then you treat patterns from "00000000" to "01111111" as the whole numbers from 0 to 127, and reserve "1xxxxxxx" for writing negative numbers.

Top 4 Ways to Use the Tilde Operator in Python - sqlpey

Exploring the Tilde Operator ~ in Python. The tilde operator (~) holds a fascinating place in Python, primarily functioning as the bitwise complement operator. It not only flips bits but is also used creatively in various arithmetic and logical operations.

What is Tilde Operator in Python - Online Tutorials Library

In Python, the bitwise operator ~ (pronounced as tilde) is a complement operator. It takes one bit operand and returns its complement. If the operand is 1, it returns 0, and if it is 0, it returns 1. For example, consider the 4-bit binary number (1100)2. By performing the tilde operation, each bit is flipped and results in (0011)2.

Bitwise Operators in Python

Python’s bitwise operators let you manipulate those individual bits of data at the most granular level. You can use bitwise operators to implement algorithms such as compression, encryption, and error detection as well as to control physical devices in your Raspberry Pi project or elsewhere.
