Python’s bitwise OR operator x | y performs logical OR on each bit position on the binary representations of integers x and y. Each output bit evaluates to 1 if and only if at least one of the two input bits at the same position are 1. For example, the integer expression 4 | 3 … Read more
[toc] Introduction As a programmer, you need to work on different time-based tasks in your program like logging and saving the records to the database and accessing the documents. In each of those cases, date and time assume a significant part in saving the importance and integrity of the data and information. So, you must … Read more
Это руководство покажет вам, как преобразовать строку Юникода в строку в Питоне. Если вы уже знаете о Юникоде, вы можете пропустить следующий раздел, посвященный справочной информации, и сразу же погрузиться в проблему. Истоки Юникода Немного о Юникоде из Википедии. Юникод — стандарт кодирования символов, включающий в себя знаки почти всех письменных языков мира. В настоящее … Read more
In the previous article, we got acquainted with Unicode and methods of processing input Unicode strings, different ways of processing and converting them into a readable form – string objects in Python. Let’s look at ways of converting to other types of output data and applying different encodings to them. Problem Formulation Suppose we need … Read more
В предыдущей статье мы познакомились с Юникодом и способами обработки входных юникодных строк, разным способам обработки и преобразования их в читаемый вид – объекты типа стринг в Питоне. Рассмотрим способы преобразования в другие типы выходных данных и применение различных кодировок к ним. Формулировка задачи Предположим, нам требуется отдать данные в виде символов представленных как целые … Read more
Python Convert Unicode to Bytes Converting Unicode strings to bytes is quite common these days because it is necessary to convert strings to bytes to process files or machine learning. Let’s take a look at how this can be accomplished. Method 1 Built-in function bytes() A string can be converted to bytes using the bytes() … Read more
Python’s bitwise AND operator x & y performs logical AND on each bit position on the binary representations of integers x and y. Thus, each output bit is 1 if both input bits at the same position are 1, otherwise, it’s 0. For example, the integer expression 4 & 3 is translated to binaries 0100 … Read more
A typical online search queries the meaning of data abstraction in Python. When I began learning Python, the answers I found caused more confusion than they solved. Today I will describe data abstraction in a clear way that will assist you in better understanding the concept. We will then apply that concept in code to … Read more
Python’s not operator returns True if the single operand evaluates to False, and returns False if it evaluates to True. Thus, it logically negates the implicit or explicit Boolean value of the operand. As you read through the article, you can also watch my video for supporting explanations: Python Not Operator on Boolean You can … Read more
Today we’re going to look at the Python Method Resolution Order or MRO for short. If you’ve been following the tutorials on Python classes and inheritance, and you’ve been practicing in code, you’ll understand that once the hierarchy of classes moves into multiple inheritances, you may return strange results or end up with incomprehensible errors. … Read more
Python’s or operator performs the logical OR operation that returns True if at least one of the operands evaluates to True. The operator performs an optimization called short-circuiting, so if the first operand evaluates to True, it returns the first right away without further evaluating the second, and if the first operand evaluates to False, … Read more
Python’s and operator performs the logical AND operation that returns True if both operands evaluate to True. The operator performs an optimization called short-circuiting, so if the first operand evaluates to True, it returns the second operand; and if the first operand evaluates to False, it returns False without further evaluating the second operand. As … Read more
