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. ])

float numbers with range () function
Yes, range(0, 101) literally gives the integers from 0 to 100. If you want to know if a number is between two values, use a chained comparison: while 0 <= score < 101: Although note you shouldn't get an actual error, just a False. What exact error message did you see? More on reddit.com

You wouldn't want the range function to handle floats - you'd get round-off errors, which would lead to unexpected bugs (i.e. occasionally one extra iteration). Always iterate over ints and convert to floats! for i in range(16): degrees = 360 / 16 # etc More on reddit.com

Working with `range`-like Function for Floats in Python - CodeRivers
February 22, 2026 - The syntax is range(start, stop, step), where start (default 0), stop (exclusive), and step (default 1) are all integers. The reason it doesn't support floats is mainly due to how Python's integer arithmetic is more straightforward and efficient compared to floating-point arithmetic.

April 19, 2022 -
Hi, I have a section of code which takes a score from the user, typecasts it into a float value and saves it under the variable name "score". Then I have a line of code which reads:
while score not in range(0, 101):
However, when I input a float, I get an invalid input error message from python. I think it's because I can't use the range() function with floats. Is there a way around this? If anyone knows how to solve this, then your help would be greatly appreciated. Thank you in advance.

You got your answer. But it triggered a thought. People in this sub are often asking for suggestions on projects. If this was an operation I thought I might be doing a lot, I might ask myself, "could I implement some object (not called range) that would have this behavior?" So that might make an interesting exercise. You'd probably want to do two things. Define a class, for instance called Interval, such that Interval(start, end) worked as an initializer. And Implement the "in" operator for your class. Is that possible? Why yes it is. You can override most operators to give them your own meaning for your own class. Even if I didn't have huge use for this, I might try it just as a learning exercise for those two things. As you can see in the Stackoverflow link, it's only a couple of lines of code.

May 25, 2020 - But we still need to be careful with the range as we cannot add the numbers (due to the same overflow). The solution is to push in the division onto each component: The key insight being that no matter what numbers we add, if they have both been divided with two they can never overflow. The code follows from the formula: float midpoint = max/2 + min/2; float half_range = max/2 - min/2; int plus_minus = rand.nextBoolean() ?

Convert the floating steps into integer steps. You'll get less drift from error due to rounding of floats:
def float_range(start,stop,step):
istop = int((stop-start) // step)
for i in range(int(istop)):
yield start + i * step

The main reason you're getting answers wrong is the top level if statements are wrong. You don't want to look at the boundaries when deciding which way to move. It's legal to ask for a range that has nothing in it (with e.g. stop less than start with a positive step).
Here's how I'd minimally adjust your code to work properly:
def float_range(start,stop,step):
x = start
my_list = []
if step > 0:
while x < stop:
my_list.append(x)
x += step
else: # should really be if step < 0 with an extra check for step == 0
while x > stop:
my_list.append(x)
x += step
return my_list
