交互运行pyprocessing脚本时，TypeError:super(type，obj)

问题描述

Python 2.7.3:

Python 2.7.3:

创建最简单的 pyprocessing 文件，并将其另存为foo.py:

from pyprocessing import *

def setup():
    size(100,100)

def draw():
    rect(10,10,10,10)

run()

现在使用python:

Now in python:

>>> execfile('foo.py')

文件按预期运行.关闭pyprocessing窗口以返回提示并键入:

The file runs as expected. Close the pyprocessing window to return to the prompt and type:

>>> execfile('foo.py')

这是怎么回事?这是我是否错误地使用pyprocessing的错误?

What is happening here? Is this a bug are am I using pyprocessing wrong?

推荐答案

它作为子进程每次都会生成一个单独的进程:

This works as subprocess spawns a separate process each time:

from subprocess import call 
call([sys.executable, 'foo.py'])

有关subprocess.call的完整讨论，请参见此SO问题.

See this SO question for a fuller discussion of subprocess.call.
