Declare a variable based on a conditional

[Jake5237]

I am trying to declare a variable based on a conditional, the following code is an idea that illustrates the intention:

import numpy as np

a = 23
b = 54
c = 60

    Qs = if a < b:
        Qs = 1
    elif a < b < c:
        Qs = 1.4*a
    else:
        Qs = 0.69*b

Best regards.

You're not declaring a varibale, but assigning it a value based upon a condition.

Two of many possible implementations:

Fred,

I'm afraid this is not correct. There's an else-if between the first and second condition. In this case, with the given a, b and c, the first two conditions are both true,

but the first must prevail, becasue of the else-if.

The 'return's in my program take care of this else-if. the if() function does it also, but the vector operations don't.

Maybe this mends it:

With that:

you get

Are you sure about the condition a<b ?

Shoudn't it rather be something like b<=a ?
