Answer:
Watermark
Explanation:
This is actually called a Watermark. It is usually used as a way of showing the name or logo of the author who owns the content that is underneath the watermark. This is done so that individuals cannot steal the owner's work and use it as their own. Usually, the owner has the original version of the content without any watermark, as well as individuals that have purchased the content or a licence to use the content for personal or commercial usage.

Answer:
1, 4, 7
Explanation:
The instruction in the question can be represented as:
for i in range(1,10,3):
    print i
What the above code does is that:
It starts printing the value of i from 1
Increment by 3
Then stop printing at 9 (i.e.. 10 - 1)
So: The sequence is as follows
Print 1
Add 3, to give 4
Print 4
Add 3, to give 7
Print 7
Add 3, to give 10 (10 > 10 - 1).
So, it stops execution.
 
        
             
        
        
        
Answer:
The output is: Your cost is  100
Explanation:
Given
The above code snippet
and

Required
Determine the output of the code
if cost < 70 or cost > 150
The above condition checks if cost is less than 70 or cost is greater than 150
This condition is false because 100 is neither less than 70 nor is it greater than 150
So, the else statement will be executed.
discount = cost
Which means
discount = 100
So, the print instruction will print: Your cost is  100
