What is tilde (~) operator in Python?
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. Tilde Operation on Decimal Numbers When we perform a tilde operation on decimal numbers, the following steps are involved: Convert the decimal number to binary, including the sign. If the number is positive, place 0 in ...
Read MoreWhat is behavior of ++ and -- operators in Python?
In C/C++, Java, etc., ++ and -- operators are defined as increment and decrement operators. In Python, they are not defined as operators. Increment and Decrement Operators in Python In Python, objects are stored in memory. Variables are just labels. Numeric objects are immutable. Hence, they can't be incremented or decremented. However, prefix ++ or -- doesn't give an error but doesn't perform either. As Prefix In the following example, when have used prefix increment which does not raise an error - x=5 print(++x) print(--x) Following is the output of the above code - 5 5 As Postfix In ...
Read MoreHow do we reference Python class attributes?
In Python, the variables that are declared inside the class are known as attributes. These attributes can be accessed and modified by both the class and its objects. Following are the two types of attributes - Class Attributes: The attributes that are defined globally in the class are known as class attributes and can be accessed throughout the class itself and are shared between all class instances. They can be accessed using the class name. Instance Attributes: The attributes that are defined inside the __init__() method are known as instance attributes. ...
Read MorePython program to capitalize each word\\\'s first letter
Let's understand the problem statement: we need to convert a given strings to a title case, which involves capitalizing the first letter of each word while converting the remaining letters to lowercase. The following are the various ways to capitalize each word's first letter in a string - Using title() method Using capitalize() method Using upper() method Importing string module Importing regex module Capitalizing a String in a File Using the title() method to ...
Read MoreHow to write Python regular expression to match with file extension?
Using Python, we can easily search for specific types of files from a mixed list of file names using regular expressions. For this, we need to import Python’s built-in module called re using the import keyword. The Regular expression or Regex is a special sequence of characters like \, *, ^, etc, which are used to search for a pattern in a string or a set of strings. It can detect the presence or absence of characters by matching them with a particular pattern and can also split a string into one or more substrings. The following is a syntax ...
Read MorePython - Replace duplicate Occurrence in String
In this article, we will explore different ways to replace duplicate occurrences in a string. Before understanding the solution let's try to understand the problem statement with an example. Consider a string "Ram lives in Hyderabad. Ram is studying in class 10. Ram is the class Monitor of the class." In this string "Ram" appears multiple times we need to replace the duplicate occurrences with 'He', keeping the first occurrence unchanged. Replacing Duplicate Occurrences in a String Following are the multiple ways to replace duplicate occurrences in a string − Using List comprehension ...
Read MoreGetting console.log output from Chrome with Selenium Python API bindings.
We can get console.log output from Chrome with Selenium Python API bindings. We will perform this with the DesiredCapabilities class. We shall enable logging from the browser with DesiredCapabilities.Chrome setting. We have to pass this browser capability to the driver object by passing it as a parameter to the Chrome class. To enable logging we shall set the property goog:loggingPrefs of the browser to 'browser':'ALL'. Syntax Syntax:dc = DesiredCapabilities.CHROME dc['goog:loggingPrefs'] = { 'browser':'ALL' } driver = webdriver.Chrome(desired_capabilities=dc) Example from selenium import webdriver from selenium.webdriver.common.desired_capabilities import DesiredCapabilities #set browser log dc = DesiredCapabilities.CHROME dc['goog:loggingPrefs'] = { 'browser':'ALL' } driver ...
Read MorePython program to display Astrological sign or Zodiac sign for a given data of birth.
In this article, let's try to find the user's astrological sign for a given data of birth. The user input data will be compared with predefined data ranges for each zodiac sign using programming logic. For example, we can infer that the user is a Taurus if their birthdate falls between April 20 and May 20. The 12 astrological sun signs, also known as zodiac signs, are based on specific periods throughout the year. Each sign corresponds to a particular range of dates, representing distinct personality traits, characteristics, and influences. These sun signs are − ...
Read MorePython Program to Print an Inverted Star Pattern
In this article, let's try to print an inverted star pattern. This pattern involves publishing a series of stars(*) in each line arranged in a descending order. For example, if the N=5 then the output should be − ***** **** *** ** * For printing star (*) patterns frequently, we use for loops. Let's discuss the for loop in Python. Python for loop The for loop in Python provides the ability to loop over the items of any sequence, such as a list, tuple, or string. It performs the same action on each item of the sequence. This ...
Read MorePython program to find factorial of a large number
Before going to the solution let's understand about factorial. The factorial is a product of all the integers smaller than or equal to n. The mathematical representation is n!=n*(n -1)*(n-2)*(n-1)*....1 .For an example, 4! = 4*3*2*1 is 24. In this article let's try to find the different ways to find the factorial of a large number. Various Methods Following are multiple ways to find the factorial of a large number in Python − Using 'math' Module Using 'for' loop Using 'array' Using the ...
