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).
Tarea
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 withindist_mivariable. - Output the value of
dist_mi. - Convert
dist_miinto integer, and output this value.
