March 30, 2026 - For a deep dive into its exclusive stop behavior, see our guide on Is Python Range Inclusive? Stop Value Explained. This integer-only rule is non-negotiable. It is a core part of the function's contract. This ensures predictable and fast performance in loops. The simplest alternative is a list comprehension. You can use the integer range() to control iterations. Then, calculate the float value inside the loop. This gives you full control over the step size. # Generate a sequence from 0.0 to 2.0 in steps of 0.2 step = 0.2 num_steps = int((2.0 - 0.0) / step) + 1 # Calculate number of items float_sequence = [0.0 + i * step for i in range(num_steps)] print(float_sequence)

You can either use:
[x / 10.0 for x in range(5, 50, 15)]
or use lambda / map:
map(lambda x: x/10.0, range(5, 50, 15))

I used to use numpy.arange but had some complications controlling the number of elements it returns, due to floating point errors. So now I use linspace, e.g.:
>>> import numpy
>>> numpy.linspace(0, 10, num=4)
array([ 0. , 3.33333333, 6.66666667, 10. ])

It's relatively simple by creating an inclusive integer range from 2*min to 2*max and dividing it by 2:
df.with_columns(b = pl.col.a.list.eval(
pl.arange(2*pl.element().min(), 2*pl.element().max() + 1) / 2
))

pl.int_ranges()to create lists of integers.pl.Expr.repeat_by()to create a list of2with the same length, so we can divide the first list by it.
df.with_columns(
b = pl.int_ranges(2*pl.col.a.list.min(), 2*pl.col.a.list.max() + 1)
).with_columns(
pl.col.b / pl.lit(2).repeat_by(pl.col.b.list.len())

In [1]: import numpy as np
In [2]: np.repeat(1 / 10**np.arange(1, 5), 2)[1:] * np.array([1., 5.]*4)[:-1]
Out[2]: array([0.1 , 0.05 , 0.01 , 0.005 , 0.001 , 0.0005, 0.0001])
Generalizing for any "pattern":
def rates(smallest_magnitude, pattern):
n = len(pattern)
pows = np.repeat(1 / 10**np.arange(1, smallest_magnitude), n)[(n-1):]
mults = np.array(pattern * (smallest_magnitude - 1))[:-(n-1)]
return np.round(pows * mults, smallest_magnitude)
Demo:
In [4]: print(*rates(5, [1, 5])) # Your original 'pattern'
0.1 0.05 0.01 0.005 0.001 0.0005 0.0001

This works, but I'm not sure it's any better than your method.
import numpy as np
# Create the powers of ten:
a = 0.1 ** np.arange(1,6)
# Interleave the halves in between:
a = np.concatenate((a,a/2))
# Sort and reverse:
a.sort()
a = a[-1::-1]
print(a)
