Float list in Python

Question

How to create a range list with float numbers:
numbers = list(range(0, 10, 0.5))

Answer 1

# using numpy:

import numpy as np

l = list(np.arange(0, 10, .5))

# manually:

l = [n/2 for n in range(20)]

Answer 2

There is no built-in function to create a range of floats. So you have to write a function to do this task for you.

You can try this:

new_lst = []
for i in range(0, 11):
new_lst.append(float(i))
new_lst.append(float(i + 0.5))
print(new_lst)

Answer 3

An other version, more flexible than the first one.

# creating range of floats. It does currently not work for negativ numbers.
start = 0.0
stop = 100.0
step = 0.253
res_lst = []
res_buf = start
while res_buf <= stop:
res_lst.append(format(round(res_buf, 3),'.3f'))
res_buf += step
print(res_lst)
