python reads the coordinate method in the text

Using python to read text files is very convenient, using the string module, the following uses a small example to demonstrate reading the coordinate information in the text.

import string

x , y , z = [] , [] ,[]
with open("test.txt") as A:
 for eachline in A:
  tmp = eachline.split()
  x.append(string.atof(tmp[0]))
  y.append(string.atof(tmp[1]))
  z.append(string.atof(tmp[2]))
print x,y,z

The text is as follows:

0.1 0.2 1 
0.3 0.4 2 
0.4 0.5 3 
0.6 0.7 4

Since you are reading on a row basis, you can use split() to split the read string and then convert it to a number.
