本文介绍了非常简单的程序崩溃，Python 3.5和spyder的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
xx = 0
n = 4294967295
while xx <= n:
print("xx = ", xx, bin(xx))
xx += 1
这将导致以下回溯:
File "<ipython-input-2-0c9d04ddbbc6>", line 1, in <module>
runfile('C:/Users/Allen/Documents/Python Scripts/crunchy.py', wdir='C:/Users/Allen/Documents/Python Scripts')
File "C:\Users\Allen\Anaconda3\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 714, in runfile
execfile(filename, namespace)
File "C:\Users\Allen\Anaconda3\lib\site-packages\spyderlib\widgets\externalshell\sitecustomize.py", line 89, in execfile
exec(compile(f.read(), filename, 'exec'), namespace)
File "C:/Users/Allen/Documents/Python Scripts/crunchy.py", line 11, in <module>
print("xx = ", xx, bin(xx))
File "C:\Users\Allen\Anaconda3\lib\site-packages\ipykernel\iostream.py", line 317, in write
self._buffer.write(string)
ValueError: I/O operation on closed file
推荐答案
似乎您正在使用ipython.
It seems that you are using ipython.
根据此页面: https://github.com/ipython/ipython/issues/9168
您可能会遇到一个已知问题，并将在下一发行版中修复.顺便说一句，当我在终端中运行该程序时，该程序不会崩溃.
you might run into a know issue and will be fixed in the next release. By the way, that program does not crash when I am running it in terminal.
