Answer:
1.) 25 ; 15 ; 15
2.) 50 ; 15 ; 50
Explanation:
In the first function written :
The variable val was initially decaled or assigned a value of 25 and that was what was printed first.
However, after the example function was written, the val variable was finally assiagned a value of 15 within the function. However, it was also declared that the global variable takes uonthe val value. Hence, the val variable initially assigned a value, of 25 changes to 15 globally.
For the second code :
From the top:
Val was assigned a value of 50 ;
Hence,
print(val) gives an output of 50
Within the function definition which prints the value of val that is assigned a value of 25 within the function.
Since tbe global variable isnt reset.
Printing Val again outputs 50;since ito is outside the function.
Answer: Simple-locker
Explanation:Simple-locker is the program that works on the technique in which it automatically encrypts the data or files and then demand a certain ransom or money from the user for the decryption of that data. It works on the function to gain the ransom or incentive in the financial form.
The decryption can only be carried out in safe way when the victim has the key to decrypted data or file.
We should use Tone Generator to to trace the route that a cat 6 utp cable takes through the ceiling and walls of your building. The tone generator can be used to test the speakers and their electrical wiring, as well as to find the frequency of hearing loss and tinnitus.
A sinusoidal signal is produced by a tone generator at the selected frequency. Can be used as a learning tool for physics as well as to test audio equipment like speakers or earbuds. You may also test the frequency range of tablet speakers.

#SPJ4
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
