我可以从内容页面隐藏母版页中的用户控件吗？(Can I hide a user control in a master page from a content page?)

import sys

thismodule = sys.modules[__name__]

setattr(thismodule, name, value)
 
 或者，不使用setattr （它打破了问题的信，但满足相同的实际目的;-)： 
 
globals()[name] = value
 
 注意 ：在模块范围内，后者相当于： 
 
vars()[name] = value
 
 这有点更简洁，但不能在函数内部运行（ vars()给出了它在以下范围中调用的范围的变量：在全局范围调用时的模块变量，然后可以使用它R / W，但在函数中调用函数的变量，然后它必须被视为R / O - Python在线文档可能会有点混淆这个特定的区别）。 

import sys

thismodule = sys.modules[__name__]

setattr(thismodule, name, value)
 
or, without using setattr (which breaks the letter of the question but satisfies the same practical purposes;-):
 
globals()[name] = value
 
Note: at module scope, the latter is equivalent to:
 
vars()[name] = value
 
which is a bit more concise, but doesn't work from within a function (vars() gives the variables of the scope it's called at: the module's variables when called at global scope, and then it's OK to use it R/W, but the function's variables when called in a function, and then it must be treated as R/O -- the Python online docs can be a bit confusing about this specific distinction).
