求助报错I/O operation on closed file与为什么指代相同内容的两个变量不相等
本帖最后由 fc5igm 于 2021-6-8 22:48 编辑>>> fgirl3=open(r'D:\python\works\girl_3.txt','w')
>>> girl.writelines(each)
Traceback (most recent call last):

girl.writelines(each)
ValueError: I/O operation on closed file.
>>> girl

':滚！！！'
>>> fgirl3.close()
>>> fgirl3=open(r'D:\python\works\girl_3.txt','w')
>>> girl.writelines(each)
Traceback (most recent call last):
File "<pyshell#13>", line 1, in <module>
girl.writelines(each)
ValueError: I/O operation on closed file.
>>> girl
<_io.TextIOWrapper name='D:\\python\\works\\girl_3.txt' mode='w' encoding='cp936'>
经查，该报错往往指缩进错误。但是问题是，我用的交互界面，根本没有缩进。怎么会缩进错误呢？
求问怎么解决
找到错误原因了
>>> fgirl3.writelines(':滚！！！')
>>> girl
<_io.TextIOWrapper name='D:\\python\\works\\girl_3.txt' mode='w' encoding='cp936'>
>>> girl==fgirl3
False
>>> fgirl3
<_io.TextIOWrapper name='D:\\python\\works\\girl_3.txt' mode='w' encoding='cp936'>
>>> girl.writelines(':滚！！！')
Traceback (most recent call last):
File "<pyshell#20>", line 1, in <module>
girl.writelines(':滚！！！')
ValueError: I/O operation on closed file.
但是新的问题又来了。明明girl和fgirl3指代的完全一致，为什么girl会不等于fgirl3？
同样的指代内容，为什么fgirl3正确，girl就错误？
fgirl3和girl的原始赋值过程
f=open(r'D:\python\works\record.txt')
fboy1=open(r'D:\python\works\boy_1.txt','w')
fboy2=open(r'D:\python\works\boy_2.txt','w')
fboy3=open(r'D:\python\works\boy_3.txt','w')
fgirl3=open(r'D:\python\works\girl_3.txt','w')
fgirl2=open(r'D:\python\works\girl_2.txt','w')
fgirl1=open(r'D:\python\works\girl_1.txt','w')
for num in range(3):
boy=
girl=

原代码因为无法成功运行已经被我删掉了。用帖子中赋值相关的代码重复操作后，结果却又相等了。
可能是什么奇奇怪怪的bug吧。
发到python论坛，论坛对此的回复则是多变量对同文件的引用并不相等。
总之，因为原代码已经删除，也无法再重新验证了。不过我个人倾向于可能是发生了系统bug。
