可以發現是將test.txt打印出來，沒有去查找test.txt文件。
下面是將文件內容打印出來了。
root@ubuntu:~/dongbo/tools/python/day2# cat diedai.py
#!/usr/bin/env python
#_*_ coding:utf-8 _*_
f = file("/root/dongbo/tools/python/day2/test.txt")
for i in f:
print i,
root@ubuntu:~/dongbo/tools/python/day2#root@ubuntu:~/dongbo/tools/python/day2# python diedai.py wo ai ni chenxiaoyandongbo dongbo ai chenxiaoyan
下面的方式就是把每個字符打印出來了。
root@ubuntu:~/dongbo/tools/python/day2# cat diedai.py
#!/usr/bin/env python
#_*_ coding:utf-8 _*_
f = file("/root/dongbo/tools/python/day2/test.txt")
for i in f.readline():
print i,
root@ubuntu:~/dongbo/tools/python/day2# python diedai.py
