I need to create a class whose object will return the same values ​​when

test_class.test_variable

and

test_class['test_variable']

Please let me know if this is possible and if so, how.

CodePudding user response：

You can use getattr to lookup an attribute by name, and use that to implement __getitem__ for your class.

class test:
    def __init__(self, var):  
        self.var = var
    def __getitem__(self, s):
        return getattr(self, s)

>>> t = test(5)
>>> t.var
5
>>> t['var']
5
