Use range. In Python 2, it returns a list directly:
>>> range(11, 17)
[11, 12, 13, 14, 15, 16]
In Python 3, range is an iterator. To convert it to a list:
>>> list(range(11, 17))
[11, 12, 13, 14, 15, 16]
Note: The second number in range(start, stop) is exclusive. So, stop = 16+1 = 17.
To increment by steps of 0.5, consider using 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]

Create List of Numbers with Given Range - Python - GeeksforGeeks
range() generates an iterator that produces numbers within a specified range. It is highly efficient as it doesn’t create the entire list upfront, making it memory-friendly. Converting the iterator to a list gives us the full range of numbers.

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]

The itertools module is part of the Python standard library and is used for efficient looping and iterable manipulation. One useful function from itertools is count(). It creates an iterator that generates consecutive integers indefinitely. To create a finite range, you can combine it with islice() from the same module. ... from itertools import count, islice # Creating a list of numbers from 5 to 10 numbers = list(islice(count(5), 6)) print(numbers)

Python range() Function
This use of list() is only for printing, not needed to use range() in a loop. >>> list(range(5)) [0, 1, 2, 3, 4] >>> list(range(10)) [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> list(range(2)) [0, 1] What is range(0)? Well range(n) returns n numbers, so this case returns no numbers at all - like the empty list.

You can just construct a list from the range object:
my_list = list(range(1, 1001))
This is how you do it with generators in python2.x as well. Typically speaking, you probably don't need a list though since you can come by the value of my_list[i] more efficiently (i + 1), and if you just need to iterate over it, you can just fall back on range.
Also note that on python2.x, xrange is still indexable1. This means that range on python3.x also has the same property2
1print xrange(30)[12] works for python2.x
2The analogous statement to 1 in python3.x is print(range(30)[12]) and that works also.

In Pythons <= 3.4 you can, as others suggested, use list(range(10)) in order to make a list out of a range (In general, any iterable).
Another alternative, introduced in Python 3.5 with its unpacking generalizations, is by using * in a list literal []:
>>> r = range(10)
>>> l = [*r]
>>> print(l)
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
Though this is equivalent to list(r), it's literal syntax and the fact that no function call is involved does let it execute faster. It's also less characters, if you need to code golf :-)

The difference is the "step" amount between numbers is now custom. Once the number is equal or goes beyond the stop, the range ends. As before, the stop number itself is always omitted. >>> list(range(0, 10, 2)) [0, 2, 4, 6, 8] >>> list(range(0, 10, 6)) [0, 6] >>> list(range(200, 800, 100)) [200, 300, 400, 500, 600, 700]
