Python’s bitwise XOR operator x ^ y performs logical XOR on each bit position on the binary representations of integers x and y. Each output bit evaluates to 1 if and only if exactly one of the two input bits at the same position are 1. For example, the integer expression 4 ^ 3 is … Read more
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
Problem Formulation Given a string s. Create a new string based on s with all control characters such as ‘\n’ and ‘\t’ removed. What is a Control Character? A control character, also called non-printing character (NPC), is a character that doesn’t represent a written symbol. Examples are the newline character ‘\n’ and the tabular character … Read more
Python Delete File To delete a file in Python, import the os module with import os and run os.remove(filename) in your script. The following code removes the file ‘file.dat’ from the current folder assuming the Python script resides in the same directory: Python Delete Files in Folder To delete a folder or directory with all … 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
[toc] ?️ Company Tags: Google, Facebook, Amazon Are you gearing up for your coding interview? If your answer is yes, then here’s a very important and commonly asked interview question for you. Numerous programmers have claimed that they came across this interview question. Hence, there is a high probability that you might come across it … 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
You may have read about the ‘V’s in Big Data: Volume, Velocity, Variety, Veracity, Value, Volatility. Variance is yet another important ‘V’ (it measures Volatility of a data set). In practice, variance is an important measure with important application domains in financial services, weather forecasting, and image processing. Variance measures how much the data spreads … Read more
