获取到目前为止在 Python 解释器会话中输入的代码

Question

到目前为止，是否有一种快速、方便的方法将所有代码输入 python 解释器？例如，如果我在解释器中输入：

Steven$ python
Python 2.7.5 (default, Mar  9 2014, 22:15:05) 
[GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> print "hi"
hi
>>> a = [1,2,3]
>>> for e in a:
...   print e
... 
1
2
3
>>> print "bye"
bye
>>>

我想得到这些行：

print "hi"
a = [1,2,3]
for e in a:
  print e
print "bye"

Answer 1

%history 魔法函数应该为您完成。

In [1]: l = [1,2,3]

In [2]: %history
l = [1,2,3]
%history

如果您发现自己经常这样做，请考虑使用 ipython notebook.

Answer 2

您可以使用 readline 模块。

Python 2.7.5 (default, Nov  3 2014, 14:26:24) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> print "hi"
hi
>>> a = [1,2,3]
>>> for e in a:
...     print e
... 
1
2
3
>>> print "bye"
bye
>>> import readline
>>> readline.write_history_file('history.py')

文件 history.py 将包含您的历史记录，包括最后两行：

$ cat history.py
print "hi"
a = [1,2,3]
for e in a:
    print e
print "bye"
import readline
readline.write_history_file('history.py')
