  Program Code: Program Explanation: The function sum_even_numbers takes a single argument numbers, which is a list of integers. The function uses a list comprehension to create a new list of even_numbers containing only the even numbers from the input list. This is done using the modulo operator %, which returns the remainder of dividing a number by 2. If the remainder is 0, then the number is even, and it is added to the even_numbers list. The sum function is then called on the even_numbers list to compute the sum of all the even numbers in the list. The sum of the even numbers is returned as the output of the function. Overall, this function is a simple and efficient way to compute the sum of even numbers in a list of integers.

  An Armstrong number is a number that is equal to the sum of its own digits each raised to the power of the number of digits in the number. For example, 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153. Program Code: Program Explanation: We first take an input integer from the user using the input() function and convert it to an integer using the int() function. We determine the number of digits in the input number by converting it to a string using the str() function, getting its length using the len() function, and storing the result in the variable num_digits. We initialize a variable called sum_of_cubes to 0, which will hold the sum of the cubes of each digit in the input number. We use a for loop to iterate over each digit in the input number. Since the input number is an integer, we first convert it to a string using the str() function so that we can iterate over each of its digits. For each digit, we convert it back to an integer using the int() function, cube it us...

  1. Program Code: 2. Program Explanation: We define a function called Fibonacci that takes an integer n as input. We initialize the first two terms of the Fibonacci series to 0 and 1, respectively, using tuple unpacking: a, b = 0, 1. These values will be updated as we generate the series. We check if n is equal to 0 or 1. If n is 0, then we return an empty list because there are no terms in the series. If n is 1, then we return a list with the first term of the series, which is 0. If n is greater than 1, then we initialize a list called fib_series with the first two terms of the series, which are 0 and 1. We use a for loop to iterate over the range from 2 to n - 1, since we've already accounted for the first two terms of the series. Inside the loop, we compute the next term of the series by adding the previous two terms: c = a + b. We then update the values of a and b to prepare for the next iteration: a, b = b, c. Finally, we append the new term c to the list of series terms: f...

So, today we'll be discussing how we can make the Fibonacci series using python. What is the Fibonacci series? In the Fibonacci sequence, the sum of the two preceding numbers. it is commonly started with 0 and 1. You can read more about the history of the Fibonacci series on Wikipedia . Now, let's see how we can calculate it in python. In this python program:  We're first taking input from the user that how many terms he wants to print. (User input) Then, we have made two conditions to check if the user enters a negative number or first number so we print that accordingly. If the above of the two conditions are false then the while loop will run to print the fibonacci numbers.

Today we'll be discussing how you can connect Microsoft SQL Server Database(2019) with Python. So, you have been here then I'm assuming you know pretty much about Python programming. First, you need to install pyodbc using pip - the python package manager. Now, you'll be thinking what is pyodbc? It is an open-source Python module that makes it super easy for us to access ODBC datasbases. Enter this command in your terminal: pip install pyodbc Now you need two more things to move forward: 1. Your SQL Server Instance Name 2. And your database name which you want to connect. Here's the code to connect your SQL database successfully with Python. Note: My instance is blank because I have used the default instance when installing SQL Server.

So, today we'll learn how we can swap using two variables only. using three variables is popular among programmers and they think it can't be done using two variables.  But it's not the case it can be done, of course in certain conditions, such as only in numbers. We can use some maths and sort the values of variables easily. Let's how to do swapping in python using two variables only. EASY CHEESY So, here's the logic which you need to understand, instead of memorizing the code. Let's consider: a = 1 b = 2 So we'll do some maths in it to swap it. a = 1 + 2, a is now equal to 3  b = 3 - 2, b is now equal to 1  and finally, a = 3 - 1, a is now equal to 2. swapping done using some simple maths. Here's how you can do it in python.  

The world is moving fast, everyone wants more work in less time. This is the biggest reason why users have no patience for website with poor loading time. In this internet world it is must to have a lightning-fast website. While page load time matters more on mobile or tablets, in which AMP has played a significant role. Additionally, website speed also matters in search engine rankings. Facts and Studies These are certain facts and studies about website speed. Users Wants Speedy Website In the survey and feedback, of 1,048 online shoppers, Forrester Consulting concluded that: 47% users expects that a webpage would load in or under two seconds. 40% leaves the website if web takes more than three seconds to load. 52% stated fast loading page is important for devotion to site. Lost in Conversions A 1 second delay in page response can result in a 7% reduction in conversions. Lost in Business If users distracted from loading time then 14 will shop from another websit...

Learn, how you can sort values using three variables easily. However, there are many methods you can do it from here is the one. After including the library and creating the main method. 1. First, we'll declared three variables 'n1', 'n2' , 'n3' and temporary variable 'temp' 2. Then, we'll be taking input from users in these three variables, 'n1', 'n2', 'n3' 3. After that we're using the if-else condition to swap variables: if n1 is greater than n2, then we're swapping the value using the temporary variable if n2 is greater than n3, then we're swapping the value using the temporary variable if n1 is greater than n3, then we're swapping the value using the temporary variable 4. After all the swapping we're printing the value after swapping.

Task 1 : Design a class named StopWatch. The class contains: Private data fields are startTime and endTime with getter methods.  A no-arg constructor that initializes startTime with the current time. A method named start() that resets the startTime to the current time. A method named stop() that sets the endTime to the current time. A method named getElapsedTime() that returns the elapsed time for the stopwatch in milliseconds. Write a test program and create a stopwatch and call all methods. Solution : The task is explanatory itself, if you focus however here's an explanation for you: First of all, declare two private data fields 'startTime' & 'endTime' as said in the task, as we know the time can set in seconds means values in points, therefore, we have to use data type float. Then, we have asked to create a no argument constructor which will be used to initialize the current time.  Then we have to create methods of s...

How This Program Works? First, we'll write a function in which we'll create 4 conditions to check whether number lies in the first, second, third or fourth quadrant. For first quadrant value of x and y should be greater than 0. For the second quadrant value of x should be less than 0 and the value of y should be greater than 0. For the third quadrant value of x should be less than 0 and the value of y should be greater than 0. For the fourth quadrant value of x should be greater than 0 and the value of y should be less than 0. Then in the main method, we'll take the value of x and y from the user and pass the value to the function to check in which quadrant value lies.
