Question

Hi I have a django form choice field, which needs a choice selection of range 85-150 at 5 unit increments. Unfortunately I can’t do this:

wind_range = range(85, 150, 5)

WIND_SPEED_CHOICE = (
    for i in wind_range:
        (i, i),
)

Any suggestions?

Any help much appreciated.

Answer 1

Quoting django model field reference doc:

Finally, note that choices can be any iterable object — not
necessarily a list or tuple. This lets you construct choices
dynamically.

This means that this can be a solution to you:

wind_range = range(85, 150, 5)    
WIND_SPEED_CHOICE =  [ (i, i) for i in wind_range ]
