[buran]

is that right?

yes, it was my confusion how you want to calculate weight

for example

def adrenalin():
    weight = int(input("Hvad vejer patienten? ")) #what does the patient weight
    left = weight % 5
    weight -= left
    if left > 2:
        weight += 5
    dosis = min(weight * 0.01, 0.5)
    print(f"Du skal give {dosis:.2f} mg, sv. {dosis:.2f} ml!")
