python-3.x - 为什么导入的值不可调用

Question

如果我导入了重新排列名称，为什么不能调用它？

import rearrange_name
import unittest


class TestRearrange(unittest.TestCase):
    def test_basic(self):
        testcase = "Lovelace, Ada"
        expected = "Ada Lovelace"
        self.assertEqual(rearrange_name(testcase), expected)

    def test_empty(self):
        testcase = ""
        expected = ""
        self.assertEqual(rearrange_name(testcase), expected)

    def test_double_name(self):
        testcase = "Hopper, Grace M."
        expected = "Grace M. Hopper"
        self.assertEqual(rearrange_name(testcase), expected)

    def test_one_name(self):
        testcase = "Voltaire"
        expected = "Voltaire"
        self.assertEqual(rearrange_name(testcase), expected)


unittest.main()
