1) readline 每次读一行,返回序列
2) readlines 一次全部读出,返回序列
3) numpy 的genfromtxt,返回为np的矩阵格式
import numpy as np
f=file('sample.txt','r')
ll=np.genfromtxt('sample.txt',dtype=None)
lline=f.readlines() print ll,lline
for line in lline
print line
singleline=f.readline()
source=line.rstrip()# 去除换行符
name = source.split(' ')[0]
ra = source.split(' ')[1]
dec = source.split(' ')[2]
