#!usr/bin/env python3#-*- coding:utf-8 -*-import re def COUNTT(A,B,C):    return (A[0]*B[1]*C[2] + B[0]*C[1]*A[2] + C[0]*A[1]*B[2]            -C[0]*B[1]*A[2] - B[0]*A[1]*C[2] - A[0]*C[1]*B[2])if __name__ == '__main__':    M, N, P, Q = [[0]*3 for _ in range(4)]     for i in range(3):            msg = '请依次输入第{}个方程的x,y,z的系数以及常数项(以空格隔开): '        while 1:            try:                nums = re.split(r'\s+', input(msg.format(i+1)).strip())                M[i], N[i], P[i], Q[i] = [float(n) for n in nums]                break            except Exception as e:                import traceback;traceback.print_exc()                print('输入有误, 请重新输入!')    D=COUNTT(M,N,P)      if D == 0 :        print('根不存在或者有无穷多个根')    else:        print('x =', COUNTT(Q,N,P)/D)        print('y =', COUNTT(M,Q,P)/D)        print('z =', COUNTT(M,N,Q)/D)
