如何在一个类中搜索多个变量并打印另一个变量？有没有可能让这件事变得更简单？

class MyClass:
    def __init__(self, var1, var2, var3, print_var):
        self.var1 = var1
        self.var2 = var2
        self.var3 = var3
        self.print_var = print_var

    def search_and_print(self):
        if self.var1 == self.print_var:
            print("var1:", self.var1)
        if self.var2 == self.print_var:
            print("var2:", self.var2)
        if self.var3 == self.print_var:
            print("var3:", self.var3)

my_object = MyClass("value1", "value2", "value3", "value2")
my_object.search_and_print()

class MyClass:
    def __init__(self, variables):
        self.variables = variables

    def search_and_print(self, print_var):
        for var, value in self.variables.items():
            if value == print_var:
                print(var + ":", value)

my_object = MyClass({"var1": "value1", "var2": "value2", "var3": "value3"})
my_object.search_and_print("value2")
