我正在尝试获取一个python程序来获取.dat文件并将其读入矩阵.我大部分时间都在工作,但是"无"会在声明结尾处继续打印.

import sys

def main():

  matrix = generateMatrixFromFile(sys.argv[1])

  print(printMatrix(matrix))

def generateMatrixFromFile(fname):
  fp = open(fname, "r")
  row = fp.readlines()
  matrix = []
  for i in range(0, len(row), 1):
    token = row[i].split(" ")
    token[-1] = token[-1].replace('\n', '')
    matrix.append(token)
  fp.close()
  return matrix

def printMatrix(matrix):
  for i in range(0, len(matrix), 1):
    for j in range(0, len(matrix[i]), 1):
      print(matrix[i][j], sep=" ", end=" ")
    print()

main()
