ね、眠い。
とりあえず、for 文が面倒だったから、力技。

TakahashiSinformation.py
C = [list(map(int,input().split())) for _ in range(3)]
#print(C)

if C[0][1]-C[0][0] == C[1][1]-C[1][0] == C[2][1]-C[2][0]:
    if C[0][2]-C[0][1] == C[1][2]-C[1][1] == C[2][2]-C[2][1]:

        if C[1][0]-C[0][0] == C[1][1]-C[0][1] == C[1][2]-C[0][2]:
            if C[2][0]-C[1][0] == C[2][1]-C[1][1] == C[2][2]-C[1][2]:
                print("Yes")
                exit()
print("No")

問題にあるように素直に、全部試して OK なら Yes, ダメなら No
