f2=4                                           #MHz

#Calculation
import math
Cs=(C1-4*C2)/3.0
L=1/(4*(math.pi)**2*f1**2*(C1+Cs))

#Result
print"The value of distributed capacitance is ",round(Cs,2),"pf","and inductance is ",round(L*10**6,3),"micro H"

The value of distributed capacitance is  66.67 pf and inductance is  9.499 micro H
