Answer
Output
1 2
2 4
3 6
Explanation
The outer loop runs with values 1, 2, and 3. For each value of x, the inner loop runs with values 1 and 2. During each iteration, the product of x*y is printed. Thus, when x = 1, the outputs are 1 and 2; when x = 2, the outputs are 2 and 4; and when x = 3, the outputs are 3 and 6. The print() statement moves the cursor to the next line after each row is completed.

for i in range(4): for j in range(i, -1, -1): print(j, end=' ') print()Assertion (A): Loop is a repetitive structure in which a statement or a set of statements are executed until the desired number of iterations is over.
Reason (R): The for loop is used to repeat the execution of a block of statements for a fixed number of times.
Based on the above assertion and reasoning, pick an appropriate statement from the options given below:
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true and R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
- Both A and R are false.
Assertion (A): The range() function is a built-in function which is used with the for loop.
Reason (R): This function doesn't require any parameter. It is used in for loop to generate the series such as even and odd numbers, positive and negative numbers, etc.
