【为给定字符串提出数字】看到群里面试分享一个面试题 结果给定回复是不严谨的故记录一下

 

#coding:utf8
#author:mylittlegoblin

class Test_Getint:
    def get_int(self,words):
        return int(''.join(filter(str.isdigit,words)))
    def test_get_int(self):
        assert self.get_int("1b3b4n") == 134
        assert self.get_int("11b22b44b") == 112244
样写的不严谨 修改后的如下：

class Test_Getint:
    def get_int(self,words:str) -> int:
        return int(''.join(filter(str.isdigit,words)))
    def test_get_int(self):
        assert self.get_int("1b3b4n") == 134
        assert self.get_int("11b22b44b") == 112244
