Question

以下是我用来执行任务的代码。该代码可以正常运行，但是需要2分钟以上的时间才能执行。而且只有一个规则（Rule_1），该规则是使用.exe（用CPP编写）检查的。实际上，要通过这些规则需要很多CSV文件。

我的问题是程序将始终使用大量时间，因为我必须对文件实施更多的50条规则，否则还有其他方法吗？

import os
import fnmatch
import subprocess
import xml.etree.ElementTree as ElementTree
from xml.parsers.expat import ExpatError
import sys
from shutil import copyfileobj


def locate(pattern, root="Z:/Automation/"):
    '''Locate all files matching supplied filename pattern in and below
    supplied root directory.'''
    for path, dirs, files in os.walk(os.path.abspath(root)):
        for filename in fnmatch.filter(files, pattern):
            yield os.path.join(path, filename)


csv_path_unrefined = []
for xml in locate("*.csv"):
    try:
        ElementTree.parse(xml)
    except (SyntaxError, ExpatError):
        csv_path_unrefined.append(xml)
csv_path = []
for paths in csv_path_unrefined:
    if "results" in str(paths):
        csv_path.append(paths)


def check_rule1(path):
    # path = "PWLLOGGER_DEMO.csv"
    file = 'ConsoleApplication9.exe "' + path + '"'
   # print(file)
    details = os.popen(file).read()
    log_file = open("logs/Rule_1.txt")
    state = log_file.read()
    with open('results/Rule_1_log.log', 'a+') as files:
        files.write("\n========" + path + "========\n")
        files.close
    with open('results/Rule_1_log.log', 'a+') as output, open('logs/Rule_1.txt', 'r') as input:
        copyfileobj(input, output)
    if "failed" in state:
        return False
    else:
        return True


rule_1_passed = []
rule_1_failed = []

for paths in csv_path:
    result_r1 = check_rule1(paths)
    # print(result_r1)
    if result_r1 == False:
        rule_1_failed.append(paths)
        #print("Rule 1 has failed for " + paths)
    elif result_r1 == True:
        rule_1_passed.append(paths)
        #print("Rule 1 has passed for " + paths)
    open('logs/Rule_1.txt', 'w').close()


print(rule_1_failed)
print(rule_1_passed)

减少python程序的执行时间
