What will be the output of the following code snippet?for index in range(20, 10, -3) :print(index, end = ' ')

The output of the given Python code snippet will be:

20 17 14 11

Here's the step by step explanation:

1. The range() function is used with three arguments: start, stop, and step. In this case, start is 20, stop is 10, and step is -3. This means the loop will start at 20 and decrement by 3 each time until it reaches a number less than 10.

2. The for loop iterates over each number in this range.

3. The print() function is used with the end parameter set to ' '. This means that instead of printing each number on a new line (which is the default behavior), it will print each number followed by a space on the same line.

4. So, the loop first prints 20 (the start value), then 17 (20 - 3), then 14 (17 - 3), and finally 11 (14 - 3). When it gets to 11 - 3 = 8, since 8 is less than 10, it stops.
