有没有办法让python在脚本中间变得交互？

Question

我想做点什么:

do lots of stuff to prepare a good environement
become_interactive
#wait for Ctrl-D
automatically clean up

是否有可能与python？如果没有,你看到另一种方式做同样的事情？

Answer 1

启动Python时使用-i标志并设置atexit处理程序以在清理时运行.

文件script.py:

import atexit
def cleanup():
    print "Goodbye"
atexit.register(cleanup)
print "Hello"

然后你用-i标志启动Python:

C:\temp>\python26\python -i script.py
Hello
>>> print "interactive"
interactive
>>> ^Z

Goodbye

Answer 2

该code模块将允许您启动Python REPL.

Answer 3

详细阐述IVA的答案: 嵌入式shell,codeincoporating和Ipython.

def prompt(vars=None, message="welcome to the shell" ):
    #prompt_message = "Welcome!  Useful: G is the graph, DB, C"
    prompt_message = message
    try:
        from IPython.Shell import IPShellEmbed
        ipshell = IPShellEmbed(argv=[''],banner=prompt_message,exit_msg="Goodbye")
        return  ipshell
    except ImportError:
        if vars is None:  vars=globals()
        import code
        import rlcompleter
        import readline
        readline.parse_and_bind("tab: complete")
        # calling this with globals ensures we can see the environment
        print prompt_message
        shell = code.InteractiveConsole(vars)
        return shell.interact

p = prompt()
p()

Answer 4

使用IPython v1.0,您可以简单地使用

from IPython import embed
embed()

Answer 5

不完全是你想要的东西,但python -i将在执行脚本后启动交互式提示.

-i :运行脚本后交互式检查,(也是PYTHONINSPECT = x)并强制提示,即使stdin似乎不是终端

$ python -i your-script.py
