Question

What is the output of the following range () function for num in range (2,-5,-1): Print (num,end = ",")

Answer 1

Answer:

Since momentum is the same for the lighter as well as the heavier body then we can say that the lighter body moves with a greater velocity. We know that momentum is the product of velocity and mass of a particle.

Explanation:

Answer 2

Concept:

The range() function returns a number series that starts at 0 (by default) and advances by 1 (by default) until it reaches a specified value.

Syntax:

range(start, stop, step)

Given:

for num in range(2,-5,-1):

   print(num, end=", ")

Find:

Find the output of the given code.

Solution:

start  - It is an optional parameter. It is an integer number specifying at which position to start. The default value of start is 0.

stop - It is a required parameter. It is an integer number specifying at which position to stop (stop is not included).

step - It is an optional parameter. It is an integer number specifying the incrementation. The default value of step is 1.

In given program:

start = 2

stop = -5

step = -1

∴ Output will be $2, 1, 0, -1, -2, -3, -4,$ .
