如何更改初始化器中的布尔参数，使其在有参数时变为true，而在Python3.6中没有参数时保持false？

def __init__(self, bool_param=False):
    self.bool_param = bool_param

def __init__(self, bool_param=False, param=None):
    self.bool_param = bool_param
    if param is not None:
        self.bool_param = True

class MyClass:
    def __init__(self, bool_param=False, param=None):
        self.bool_param = bool_param
        if param is not None:
            self.bool_param = True

# 传入参数值，布尔参数为True
obj1 = MyClass(bool_param=False, param="some value")

# 没有传入参数值，布尔参数为False
obj2 = MyClass(bool_param=False)

print(obj1.bool_param)  # 输出：True
print(obj2.bool_param)  # 输出：False
