实现一个函数来来对目标字符串进行校验，使其满足以下全部条件
- 不少于6个字符
- 包含至少一个小写字母
- 包含至少一个大写字母
- 包含至少一个数字
- 只能包含大小写和数字
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()
