Numbers

As you may notice, despite having two integer numbers, Python somehow classified them with different types: one of them is int, while another is float. Also, there is one more numeric type in Python. Let's consider all of them:

int - refers to integer numbers (i.e. 3, -1, 1003 etc);
float - refers to real numbers (i.e. 2.8, 3.333, 3.0 etc);
complex - refers to complex numbers (i.e. 3+2j).

To make Python understand that you want to assign to a variable specific type, use int() for converting to an integer, float() - to real, complex() - to complex.

Returning to our question above, Python assigned float type to variable days as it wants to "play it safe", insofar as the division of two integers is not a compulsory integer (unlike multiplication, subtraction, or addition).

Завдання

The distance between San Francisco and New York is about 4677.4 km (by roads). This value is saved in dist_km variable. Your tasks are:

Convert the distance to miles by diving distance in kilometers by 1.609 (approximately). Save the result within dist_mi variable.
Output the value of dist_mi.
Convert dist_mi into integer, and output this value.
