Python讀取文字檔案到陣列

支援的格式有txt, dat, csv, mat等

讀入的資料存為float型別, 可以自定義資料之間的間隔符, 可以自定義列數cols

import numpy as np

import linecache
# import os
filename =
"data.dat"
cols =
12# number of column
divided_ch =
' '# divided_character between numbers
defdat_to_matrix
(filename)
:file
=open
(filename)
lines =
file
.readlines(
) rows =
len(lines)
datamat = np.zeros(
(rows, cols)
) row =
0for line in lines:
line = line.strip(
).split(divided_ch)
# strip remove block space in line
datamat[row,:]
= line[:]
row +=
1return datamat
data = dat_to_matrix(filename)
print
(data)
