找出以ip开头的字符串
_input = [‘ip_10.2.223.5‘, ‘ip_10.2.220.3‘, ‘port_22‘, ‘port_8001‘, ‘port_80‘, ‘ip_172.16.8.35‘]

for item in _input:
    if item.startswith(‘ip‘):
        print(item)

def get_int(n):
    if isinstance(n,int):
        return True
    else:
        return False
    
_input = [1, 2, 3, "ss", "test", [1, 2]]
    
ret = []

for item in filter(get_int,_input):
    ret.append(item)
    
print(ret)
