Dictionary with ranges that have a float step value

[Irv1n]

Hello to all!

I need to create dictionary like this:

rcd_curr = {'SOUR:SAF:RCDC': {0.025: (?????), 0.25: (???????), 2.5: (???????)}}
for key 0.025 I need generate values from 0.020 with step 0.0001
for key 0.25 I need generate values from 0.21 with step 0.001
for key 2.5 I need generate values from 2.1 with step 0.01

can anyone help with?

you could try using numpy.

import numpy as np
r1 = np.arange(0.020, 0.025, 0.0001)
for i in r1:
    print(i)

Output:
