You have done some little mistakes including the "print" in last line. See this I have corrected it👇 S = [int(x) for x in input().split()] A = [int(x) for x in input().split()] B = [int(x) for x in input().split()] totalS = len(S) totalA= len(A) totalB= len(B) p= 0 for i in S: if i == 1: p+=1 p=p/totalS giniS = 2 * p* (1-p) pL= 0 for e in A: if e == 1: pL+=1 pL=pL/totalA giniL = 2 * pL* (1-pL) pR = 0 for ee in B: if ee == 1: pR+=1 pR= pR/totalB giniR = 2 * pR* (1-pR) iG = giniS-(totalA/totalS)*giniL-(totalB/totalS)*giniR print(round(iG,5))

S = [int(x) for x in input().split()] A = [int(x) for x in input().split()] B = [int(x) for x in input().split()] p1=sum(S)/len(S) imp1=2*p1*(1-p1) p2=sum(A)/len(A) imp2=2*p2*(1-p2) p3=sum(B)/len(B) imp3=2*p3*(1-p3) i=imp1-len(A)/len(S)*imp2-len(B)/len(S)*imp3 print(round(i,5))

import numpy as np S = np.array([int(x) for x in input().split()]) A = np.array([int(x) for x in input().split()]) B = np.array([int(x) for x in input().split()]) print(round(( 2* (len(S[S==1])/len(S)) * (len(S[S==0])/len(S)) ) - (len(A)/len(S))*(( 2* (len(A[A==1])/len(A)) * (len(A[A==0])/len(A)) )) - (len(B)/len(S))*( 2* (len(B[B==1])/len(B)) * (len(B[B==0])/len(B)) ),5) )
