如何在输出期间更改值名称

original_names = {'value1': 'new_value1', 'value2': 'new_value2'}

def change_name(original_name):
    return original_names.get(original_name, original_name)

def change_name(original_name):
    if original_name == 'value1':
        return 'new_value1'
    elif original_name == 'value2':
        return 'new_value2'
    else:
        return original_name

class NameChanger:
    def __init__(self):
        self.original_names = {'value1': 'new_value1', 'value2': 'new_value2'}

    def change_name(self, original_name):
        return self.original_names.get(original_name, original_name)
