Answer:
Hey! The answer you're looking for is D. Uniform Resource Locator.
Answer:
The solution code is written in Python:
- def square(num):
- if type(num).__name__ == 'int':
- sq_num = num * num
- return sq_num
- else:
- return "Invalid input"
-
- print(square(5))
- print(square("Test"))
Explanation:
To ensure only certain type of operation can be applied on a input value, we can check the data type of the input value. For example, we define a function and name it as <em>square</em> which take one input number, <em>num </em>(Line 1).
Before the <em>num</em> can be squared, it goes through a validation mechanism in by setting an if condition (Line 2) to check if the data type of the input number is an integer,<em> int.</em> If so, the<em> num </em>will only be squared otherwise it return an error message (Line 6).
We can test our function by passing value of 5 and "Test" string. We will get program output:
25
Invalid input
I believe it is 8
Hope this helps

Answer:
Hi there! This can be implemented in a simple Python function which uses the "random" module to generate the number.
Explanation:
Using Python as the languge, we can write a the below code in a file called styles.py. The first line imports the randint function from the "random" module. The setStyles() function declares an array or 5 elements (here I have just used numbers but these could be string names of the stylesheets as well). Next, styleNum is assigned the random number and the associated stylesheet is selected from the array of stylesheets.
styles.py
from random import randint
def setStyles():
stylesheets = [1,2,3,4,5];
styleNum = randint(1,5);
stylesheet = stylesheets[styleNum];
print(stylesheet);
setStyles();
