🔒 range() with float

[prime lotus]

how can i do a for loop with the output 0, 0.1, 0.2, 0.3 ..... like range() funktion with floats?

You can set step to 0.1

Like range(0, 1, 0.1) for example,
this will increase by 0.1

etc

That could produce unpredictable results.

[late fog]

How?

[grim pebble]

>>> range(0, 1, 0.1)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer

[limpid horizon]

oh right it's also a TypeError

[tawdry escarp]

!e use integer and divide

for i in [x/10 for x in range(10)]:
     print(i)

@prime lotus it's probably best to just iterate over a range of integers then do the math yourself

[limpid horizon]

I think that's fine unless it's a lot of iterations.

[tawdry escarp]

Yeah, it's just to give an idea

[grim pebble]

idk, maybe something like that already exists, but u could also make ur own generator:

>>> def iter_float(start: float, stop: float, step: float):
...     i = start
...     while i < stop:
...         yield i
...         i += step
...
>>> for i in iter_float(0, 5, 0.25):
...     print(i)
...
0
0.25
0.5
0.75
1.0
...

@prime lotus The question is: what is it you're trying to do?

[tawdry escarp]

And I think numpy has a float range

[late fog]

Didn't know that. Oops. Thank you for that 👍.

[grim pebble]

yield is cool 😎

[late fog]

numpy.arrange could work

similar to range()

it accepts floats

I think

!e

import numpy as np

for i in np.arrange(0, 1, 0.1):
  print(i)

!e

import numpy as np

for i in np.arange(0, 1, 0.1):
  print(i)

0.30000000000000004 🗣️

[late fog]

something like that

Anyway, I think you are dealing with it better than me.

[tawdry escarp]

Yeah, float can not express 0.3 exactly.

see https://baseconvert.com/ieee-754-floating-point

>>> for i in iter_float(0, 1, 0.1):
...     print(i)

0
0.1

[grim pebble]

yeah ik
