Which of these following statements is true? The range function produces a list of numbers from the start to stop (both inclusive), with the specified step size. The only difference between the range function from the base library and the arange function from the NumPy library is that range produces a list as an output whereas arange produces a NumPy array as the output. The arange function from the NumPy library produces 50 numbers between the start and the end points (both inclusive) by default. While using linspace from the NumPy library, it is possible to get the step size (spacing between the samples) as part of the output.

Solution

The statement is partially true and partially false.

  1. The range function in Python does produce a sequence of numbers from start to stop, but it is not inclusive of the stop number.

  2. The difference between the range function and the arange function from the NumPy library is correctly stated. The range function produces a list, while arange produces a NumPy array.

  3. The arange function from the NumPy library does not produce 50 numbers between the start and end points by default. This statement is false. The number of elements produced by arange depends on the start, stop, and step parameters.

  4. The linspace function from the NumPy library does allow you to get the step size as part of the output. This is done by setting the 'retstep' parameter to True. So, this statement is true.
