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

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.

One way to create a complement from a pre-existing variable is to simply apply Python’s ~ unary negate operator. For example, let’s create a variable and its complement: All complements created from the same variable instance are not just identical, they all refer to the same object:

BitwiseOperators - Python Wiki

These are Python's bitwise operators. All of these operators share something in common -- they are "bitwise" operators. That is, they operate on numbers (normally), but instead of treating that number as if it were a single value, they treat it as if it were a string of bits, written in two's complement binary.

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.

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.

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.

Find the complement of a number - Python Forum

There is a small difference between the 1's and 2's complement. The 1's complement simply switches 0->1 and 1->0, like 1010 becomes 0101. With the 2's complement you proceed the same way, but add 1 in the end: 1010->0101 (1's complement) +0001 -> 0110 (2's complement). Now you can represent positive numbers. What about negatives?
