Python在特定文件中搜索特定错误信息，但循环输出两次

Question

import os
import sys
import re
import fnmatch
from time import sleep
#The colours of the things
class bcolors:
    HEADER = '3[95m'
    OKBLUE = '3[94m'
    OKGREEN = '3[92m'
    WARNING = '3[93m'
    FAIL = '3[91m'
    ENDC = '3[0m'
    BOLD = '3[1m'
    UNDERLINE = '3[4m'
pattern = ['*.results','*.reports','*.log','*.sum','*.summary','*.spi','*.log','*.ext','*.sum','*.summary','*.spi','*.info']
search_str = "ERROR:"
mystring = search_str.encode('utf-8')
#print len(sys.argv)
print ('checking for errors in', sys.argv[1])
if len(sys.argv) < 1:
    sys.exit('Usage: check_error.py <build directory>')
for x in pattern:
  for path,dirs,files in os.walk(sys.argv[1]):
    for fname in files:
        # Test the filename for particular pattern matches.
      if fnmatch.fnmatch(fname,x):
        fullpath = os.path.join(path,fname)
        with open(fullpath,'rb') as f:
           line = f.read()
           # Initialize counter for line number
           line_no = 1
           # Loop until EOF
           if line != '' :
           # Search for string in line
             index = line.find(mystring.lower())
             if ( index != -1) :
                 print(bcolors.FAIL + '[-]' + bcolors.ENDC + ' ', fname, ' ', search_str , ' ' , 'exists! Please check', ' ', fullpath, sep="" ) 
                 print('      ')
                 sleep(0.01)
             else:
                 print(bcolors.OKGREEN + '[+]' + bcolors.ENDC + ' ',  fname, ' ', 'OK!', sep="")
                 print("       ")
                 sleep(0.01)
                # Increment line counter
                 line_no += 1

输出看起来像

[+] prefix.log OK!
      
[-] test.log ERROR: exists! Please check logs/test.log
      
[-] test.sum ERROR: exists! Please check logs/test.sum

[+] prefix.log OK!
       
[-] test.log ERROR: exists! Please check logs/test.log
      
[-] test.sum ERROR: exists! Please check logs/test.sum

请给出解决方法

Answer 1

您看到 *.log 和 *.sum 文件的输出两次，因为这些模式在您的模式列表中出现了两次。删除重复项，您将看到您期望的输出（我认为）。

pattern = ['*.results','*.reports','*.log','*.sum', ... '*.log','*.ext','*.sum', ...]

Python在特定文件中搜索特定错误信息，但循环输出两次
