In Python, what is returned when evaluating [n for n in range(10) if n % 2]?

1 answer:

8 0

First we need to understand what "n for n in range(10)" means. Basically, we are iterating through all the values n that are in the range of 10 (meaning 0, 1, 2, 3, ..., 9).

Next we are evaluating if n%2. The percentage sign is used to represent modulus which is the remainder of when two numbers are divided. In this case, we are dividing n by 2, and the remainder is our result. When dividing by 2, the only possible remainders are 0 or 1, which when used in an if statement represent the boolean vlaues false and true, respectively. We are doing this calculation for each n from 0 to 9, and if the result is true, we output n to an array.

The numbers that will result in true (a remainder of 1) are the odds numbers. For example, 4/2 = 2 with nothing left over while 5/2 = 2 with 1 left over.

So the following is returned:

[1, 3, 5, 7, 9]

The answer is The Office Clipboard.

In most Microsoft Windows, Office Clipboard is used as a temporary storage for some software applications such as Microsoft Office Applications. It allows you to store up to 24 items either texts or graphics. For example, when you copy a text from one location this text will be temporarily stored in the clipboard until you paste them to another location.

Write a recursive function called digit_count() that takes a positive integer as a parameter and returns the number of digits in

Gelneren [198K]

Using the computational knowledge in python it is possible to write a code that Write a recursive function called digit_count()

<h3>What is a function in Python?</h3>

In Python, a function is a sequence of commands that performs some task and that has a name. Its main purpose is to help us organize programs into chunks that correspond to how we envision a solution to the problem.

<h3>Writting the code in python:</h3>

<em>def countDigits(n):</em>

<em> return 1</em>

<em> return 1 + countDigits(n / 10)</em>

Simple geometry can compute the height of an object from the the object's shadow length and shadow angle using the formula: tan(

agasfer [191]

Answer:

The program to this question can be given as:

Program:

#include <stdio.h> //include header files

#include<math.h>

int main() //main method

{

double treeHeight = 0.0; //declare variables

and assign value

double shadowLength = 0.0;

double angleElevation = 0.11693706;

// (0.11693706 radians = 6.7 degrees) convert number into angle.

shadowLength = 17.5;

treeHeight = shadowLength * tan(angleElevation); //convert number into angle

printf("Tree height: %lf\n", treeHeight); //print value.

return 0;

}

Output:

Tree height: 2.055778

Explanation:

In the above C language program firstly we include the headers. In this header file, we include a (math.h) header file this file helps to use the math function. Then we declare the main method in the main method we declare the variable that is given in the question that are treeHeight, shadowLength , angleElevation. All the variable datatype is double because it stores the floating-point value. Then we apply the formula that is treeHeight = shadowLength * tan(angleElevation). In this formula, the treeHeight variable holds the value. Then we print the variable value for print the double value we use the lf(that is long float).

obj.printOutput();

}

Explanation/Output:

// For Payroll.java

State Tax: $350.0

Federal Tax: $81.25

Dependents: $62.5

Salary: $1250.0

Take Home Pay: $881.25

// For ModifiedPayroll.java

Enter Salary:$1550.0

Enter number of Dependents:$3

State Tax: $434.0

Federal Tax: $100.75

Dependents: $116.25

Salary: $1550.0

Take Home Pay: $1131.5
