In need help to put this code in order

[loomski]

The last function should read

def E_erlang(Gos, A0):
    a = 0
    b = n
    c = 0
    Gos_c = Gos_erlang(c, n)
    while abs(a - b) > 0.000001:
        c = (a + b) / 2
        if Gos_c < Gos:
            a = c
        else:
            b = c
    return Gos_c

Also when you do this:

print('Capacity :', c)

c isn't defined anywhere.
