Python脚本未产生任何输出

Question

我有一个python脚本，试图在其中读取目录中的所有.txt文件，并确定它们是否针对脚本中的任何条件返回True或False。我没有收到错误消息，但脚本未产生任何输出。我希望脚本读取包含以.json格式格式化的文本的.txt文件。然后，我希望脚本确定.txt文件是否与下面我的代码中的任何语句匹配。然后，我想将结果输出到一个csv文件。非常感激你的帮助！#!/usr/bin/env python# regarding whether any positive results were found for the domain on VT.import csvimport jsonimport pprintimport sysimport osCSVPATH = 'CsvResults.csv'VTOUTPUTPATH = './output/'VTOUTPUTEXT = '.txt'#files_to_search = [f for f in os.listdir('./output/') if f[-4:] == '.txt']#vt_result_path = files_to_search#vt_result = vt_result_check(vt_result_path)pp = pprint.PrettyPrinter(indent=4)# Check files from VirusTotal queries for any positive results# Result is false unless any nonzero positive result is truedef vt_result_check(vt_result_path):    vt_result = None    try:        vt_result = False        for filename in os.listdir(path):            with open(filename, 'r', encoding='utf-16') as vt_result_file:                vt_data = json.load(vt_result_file)            #vt_result_path = [f for f in os.listdir('./output/') if f[-4:] == '.txt']            #vt_result = None            #try:            #    vt_result = False            #    with open(infile) as vt_result_file:            #        vt_data = json.load(vt_result_file)            # Look for any positive detected referrer samples            try:                for sample in (vt_data['detected_referrer_samples']):                    if (sample['positives'] > 0):                        vt_result = True            except:                pass            # Look for any positive detected communicating samples            try:                for sample in (vt_data['detected_communicating_samples']):                    if (sample['positives'] > 0):                        vt_result = True            except:                pass       

Answer 1

您实际上需要将这些函数称为我的兄弟

def my_func(stuff):

    print(stuff) #or whatever

my_func(1234)

每条评论更新

import os

p=r'path\to\your\files' 

filelist=os.listdir(p) #creates list of all files/folders in this dir

#make a loop for each file in the dir

for file in filelist:

    f=os.path.join(p,file) #this just joins the file name and path for full file path

    your_func(f)  #here you can pass the full file name to your functions

Answer 2

如前所述，当前的问题似乎是您根本不调用cert_check函数。但是，尽管此站点实际上不用于代码审查，但我不禁建议对您的代码进行一些改进。特别是，所有这些try/except:pass构造都使得检测代码中的任何错误变得异常困难，因为所有异常只会被静默捕获和吞噬except: pass。

• 您应该删除所有这些try/except:pass块，尤其是围绕整个功能主体的那个块

• 如果某些键不存在，则可以使用dict.get代替代替[]，这不会引发键错误，而是返回None（或一些默认值），并且所有检查仍然可以进行

• 您可以使用|=而不是if检查来or检查变量的结果

• 您可以any用来检查某个列表中的任何元素是否满足某些条件

我的vt_result_check函数版本：

def vt_result_check(vt_result_path):

    vt_result = False

    for filename in os.listdir(path):

        with open(filename, 'r', encoding='utf-16') as vt_result_file:

            vt_data = json.load(vt_result_file)

        # Look for any positive detected referrer samples

        # Look for any positive detected communicating samples

        # Look for any positive detected downloaded samples

        # Look for any positive detected URLs

        sample_types = ('detected_referrer_samples', 'detected_communicating_samples',

                        'detected_downloaded_samples', 'detected_urls')

        vt_result |= any(sample['positives'] > 0 for sample_type in sample_types 

                                                 for sample in vt_data.get(sample_type, []))

        # Look for a Dr. Web category of known infection source

        vt_result |= vt_data.get('Dr.Web category') == "known infection source"

        # Look for a Forecepoint ThreatSeeker category of elevated exposure

        # Look for a Forecepoint ThreatSeeker category of phishing and other frauds

        # Look for a Forecepoint ThreatSeeker category of suspicious content

        threats = ("elevated exposure", "phishing and other frauds", "suspicious content")

        vt_result |= vt_data.get('Forcepoint ThreatSeeker category') in threats

    return vt_result
