python输出中列表列表内的三个点

Question

我需要在python代码中调用excel表格中的单元格值以对其进行数学运算。输出与Excel表格中的原始矩阵的顺序矩阵相同。

我尝试了for循环来每次检索单元格值。但结果显示3个点。 three dots in the set of lists. This set is equal to number of rows in the matrix. Number of rows is equal to number of columns

workbook = xlrd.open_workbook('ahpresponseinpt.xlsx') 

sheet = workbook.sheet_by_index(0) 

rows = sheet.nrows
cols = sheet.ncols

matrix = []
for i in range(rows):
  row = []
  for j in range(cols):

    row.append(row)

  matrix.append(row)

print(matrix)

我期望列表中行的值。
