Is it possible to rebind print function for IronPython? I rebinded __builtins__["print"] to my custom function but it is not called when print is executed.
是否可以重新绑定IronPython的打印功能？我将__builtins __ [“print”]重新绑定到我的自定义函数，但是在执行打印时不会调用它。

That will only work in Python 2 if your program has
如果你的程序有，那只能在Python 2中使用
from __future__ import print_function
at the top. And (in Python 2 or Python 3) you don't have to do
在顶部。而且（在Python 2或Python 3中）您不必这样做
__builtins__["print"] = my_print_func
That is unnecessarily drastic and may have unforeseen side-effects in code you did not write. It is enough to change the definition of print in the local namespace, for example
这是不必要的激烈，并且可能在你没写的代码中产生无法预料的副作用。例如，在本地命名空间中更改print的定义就足够了
print = my_print_func
