Call from class in module without specifying its name
我可以从模块导入类吗,与导入模块的方式相同,例如:
1 | from module_name import * |
这样我就不必每次需要一个变量时都指定"module.class"名称了?
例子:在模块中:
1 2 3 | class SomeClass: var1 ="Hello" var2 ="Bye" |
号
在主脚本中:
1 2 3 4 5 | def print_something(text): print(text) if __name__ =="__main__": print_something(var1) #"module_name.SomeClass.var1" should not be necessary, only"var1" |
编辑:它在实际类、实际模块中的样子是什么:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70

。
您可以为此使用元编程:
1 2 3 4 5 6 7 | class GlobalNamespace(type): def __init__(cls, name, bases, dct): type.__init__(cls, name, bases, dct) globals().update({n: v for n, v in dct.items() if not n.startswith("__")}) class RGBcolors(metaclass=GlobalNamespace): ... |
然后,导入包含rgbcolors的模块
注意:请阅读对您的问题和答案的评论,解释为什么原则上这是一个坏主意。不要将类视为模块。它们是两个不同的概念。
