How to generate a float or double list using range()?

Question

t = range(10, 20, 1)

this generates a list of integer elements.

but I want to generate a list of float (double) elements with the same values like

t = range(10.0, 20.0, 1.0)

this doesn't work.

TypeError: range() integer end argument expected, got float.

Answer 1

It is not possible to do it with range. As a workaround, you may use map to type-cast the values to float as:

>>> map(float, range(10, 20, 1))
[10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 17.0, 18.0, 19.0]

Answer 2

you can type cast int to float.

>>> [float(x) for x in range(10,20,1)]
[10.0, 11.0, 12.0, 13.0, 14.0, 15.0, 16.0, 17.0, 18.0, 19.0]

Answer 3

[i*1.0 for i in range(10, 20, 1)]
