我在终端中输入了以下命令:
br@wind:~$ python
Python 2.7.3 (default, Aug 1 2012, 05:16:07)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gasp import *
>>> begin_graphics()
>>> Closed.
br@wind:~$ touch gasp.py
br@wind:~$ echo "from gasp import *" >> gasp.py
br@wind:~$ echo "begin_graphics()" >> gasp.py
br@wind:~$ cat gasp.py
from gasp import *
begin_graphics()
br@wind:~$ python gasp.py
Traceback (most recent call last):
File "gasp.py", line 1, in <module>
from gasp import *
File "/home/br/gasp.py", line 2, in <module>
begin_graphics()
NameError: name 'begin_graphics' is not defined
为什么 GASP 只在我直接在 python shell 中键入代码时运行,但在我执行 python 脚本时它不起作用?
