Get station of alignment where instantaneous radius smaller than input

Hi, I’m little bit lost in my attempt to create Python script to get station of alignment where instantaneous radius is smaller than input.

algn = IN[0]
station = IN[1]

def inR(al, st):
    r = DC.AlignmentExtensions.GetInstantaneousRadiusAtStation(al, st)["Radius"]
    return r
    
n = 1
R = 150
s = 900
num = 10

while num > 1:
    r = inR(algn,s)
    num = r-R
....s += 1
....if s == 100:
        break

OUT = s

Are those literal dot characters? You enabled some whitespace display, but in two lines you wrote literal dots. You can see in your copied code, in two lines it remained dots. It’s also visible on your screenshot: dots in those 2 lines are on the bottom of the line, while in any other lines they are in the middle.

The while loop should look like this, note there are no dots:

while num > 1:
    r = inR(algn,s)
    num = r-R
    s += 1
    if s == 100:
        break

Thank you. I don’t know how this happend.
