在 "logger" 消息中添加 "for" 循环结果

Question

我有以下功能逻辑。

def funct(arg):
    ...
    return result_list

param_list = ['param1','param2']
for my_arg in param_list
    my_results = funct(my_arg)

如何获取运行两个参数的函数的完整结果列表？有更好的组织方式吗？

按照我尝试应用该逻辑购买的答案之一，我没有得到想要的结果：

from pythonping import ping
from log_class import NetddLog

def ip_probe(ip, ip_probe_logger, ipsl):

    def ping_ip():
        try: 
            ip_probe_logger.info(f"Pinging {ip} started")
            result = ping(ip, count=5, df=True, payload='64')
            ip_probe_logger.info(f"Pinging {ip} succeded")
        except Exception as err:
            ip_probe_logger.error(f"Pinging {ip} failed {err}")

    def trace_ip():
        #function for traceroute
        pass

    ping_ip()
    #trace_ip()
    
    log_contents = ip_probe_logger.log_capture_string.getvalue()
    ipsl.append(log_contents)

    return ipsl

if __name__ == "__main__":
    ipsl = ['Start']
    ip_probe_logger = NetddLog("IP_PROBE", level="INFO") 
    ip_list = ["192.168.255.68", "192.168.254.108"]
    for ip in ip_list:
        ipsl.extend(ip_probe(ip, ip_probe_logger, ipsl))
    print('')
    for log_item in ipsl:
        print(log_item.rstrip())

我得到的结果有很多重复，但我想要实现的是在第一个 'Start' 项之后将每个单独的 ping 结果添加到 IPSL 列表。

2022-03-24 01:12:49,078|IP_PROBE|INFO: Pinging 192.168.254.108 succeded

通过将 for 循环的主体更改为：ip_probe(ip, ip_probe_logger, ipsl) 我仍然重复可能是因为第二个函数 return.

Answer 1

如果您只需要一条消息，请创建一个将输入映射到输出的字典，然后一次性将其全部打包

当心非常大的字典可能会很麻烦，您可能想要截断它、对其进行 base64 编码或做其他工作来减小结果大小

results = {}
for my_arg in param_list
    results[my_arg] = funct(my_arg)

logger.info(f"results mapping: {results}")

Answer 2

制作 my_results 列表，并在每次调用时扩展它。

my_results = []
for my_arg in param_list
    my_results.extend(funct(my_arg))

Answer 3

这种情况很少见，您可能确实需要，这可以使您的函数更加高效（因为它们可以避免创建只会被丢弃的中间列表）

def funct(input_value):
    for result in some_source(input_value):
        yield result

def funct_wrapper(input_values):
    for input_value in input_values:
        yield from funct(input_value)

收集并使用结果，将它们添加到某个集合中以供稍后显示

Answer 4

将 my_results 设为列表，并在每次迭代时追加或扩展它。这是一个例子：

def funct(arg):
    ....
    return result_list
my_results=[]
param_list = ['param1','param2']
for my_arg in param_list:
    my_results.append(funct(my_arg))
# print(my_results)

在 "logger" 消息中添加 "for" 循环结果
