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

fc5igm

>>> fgirl3=open(r'D:\python\works\girl_3.txt','w')
>>> girl.writelines(each[3:len(each)])
Traceback (most recent call last):
  File "<pyshell#8>", line 1, in <module>
    girl.writelines(each[3:len(each)])
ValueError: I/O operation on closed file.
>>> girl
<_io.TextIOWrapper name='D:\\python\\works\\girl_3.txt' mode='w' encoding='cp936'>
>>> each[3:len(each)]
':滚！！！'
>>> fgirl3.close()
>>> fgirl3=open(r'D:\python\works\girl_3.txt','w')
>>> girl.writelines(each[3:len(each)])
Traceback (most recent call last):
  File "<pyshell#13>", line 1, in <module>
    girl.writelines(each[3:len(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=[fboy1,fboy2,fboy3][num]
        girl=[fgirl1,fgirl2,fgirl3][num]

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。
