Python - Create list with numbers between 2 values?

Question

How would I create a list with values between two values I put in? For example, the following list is generated for values from 11 to 16:

list = [11, 12, 13, 14, 15, 16] 

Answer 1

Use range. In Python 2.x it returns a list so all you need is:

>>> range(11, 17) [11, 12, 13, 14, 15, 16] 

In Python 3.x range is a iterator. So, you need to convert it to a list:

>>> list(range(11, 17)) [11, 12, 13, 14, 15, 16] 

Note: The second number is exclusive. So, here it needs to be 16+1 = 17

EDIT:

To respond to the question about incrementing by 0.5, the easiest option would probably be to use numpy's arange() and .tolist():

>>> import numpy as np >>> np.arange(11, 17, 0.5).tolist()  [11.0, 11.5, 12.0, 12.5, 13.0, 13.5,  14.0, 14.5, 15.0, 15.5, 16.0, 16.5] 

Answer 2

You seem to be looking for range():

>>> x1=11 >>> x2=16 >>> range(x1, x2+1) [11, 12, 13, 14, 15, 16] >>> list1 = range(x1, x2+1) >>> list1 [11, 12, 13, 14, 15, 16] 

For incrementing by 0.5 instead of 1, say:

>>> list2 = [x*0.5 for x in range(2*x1, 2*x2+1)] >>> list2 [11.0, 11.5, 12.0, 12.5, 13.0, 13.5, 14.0, 14.5, 15.0, 15.5, 16.0]
