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:

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.

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

In the domain of NumPy, the tilde operator can be employed to invert boolean values. This is particularly handy when managing data arrays, such as filtering out NaN values. import pandas as pd. ## Creating sample data data = pd.DataFrame({'Number': [1, 2, 3, 4, np.nan]}) cleaned_data = data['Number'][~data['Number'].isnull()]

Python Booleans - W3Schools

Booleans represent one of two values: True or False. In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. When you compare two values, the expression is evaluated and Python returns the Boolean answer:

Python Course #3: Introduction to Boolean Algebra - k0nze

Boolean algebra only knows two values: true and false. Those values are usually abbreviated as t and f or 1 and 0 where 1 represents true and 0 stands for false. As you have seen in Python Course #2 on variables and data types Python has the data type Boolean or bool to represent those two values with True and False.

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?

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.
