實現一個函式來來對目標字串進行校驗，使其滿足以下全部條件

• 不少於6個字元
• 包含至少一個小寫字母
• 包含至少一個大寫字母
• 包含至少一個數字
• 只能包含大小寫和數字
  示例：
  func(“12ABcd”) -->True
  func(“12ABc”) --> False
  func(“12ABCD”) --> False
  func(“12abcd”) --> False
  func(“ABCdef”) --> False
  func(“12AB cd”) --> False

import re
import unittest
def func(str_check):
    len_flag = False if len(str_check) < 6 else True
    char_up = False if re.search('[A-Z]', str_check) == None else True
    char_down = False if re.search('[a-z]', str_check) == None else True
    digital = False if re.search('[0-9]', str_check) == None else True
    flag = True if re.search('[^A-Za-z0-9]', str_check) == None else False
    return len_flag and char_up and char_down and digital and flag

class DefaultTestCase(unittest.TestCase):
    def test_func(self):
        self.assertEqual(func('12ABcd'), True)
        self.assertEqual(func('12ABc'), False)
        self.assertEqual(func('12ABCD'), False)
        self.assertEqual(func('12abcd'), False)
        self.assertEqual(func('ABCdef'), False)
        self.assertEqual(func('12AB cd'), False)

if __name__ == '__main__':
    unittest.main()
