python自动化运维阅读笔记
IPy
域名查询DNS
#!/usr/bin/env python
import dns.resolver
domain = input('Please input an domain: ')
A = dns.resolver.query(domain, 'A')
for i in A.response.answer:
for j in i.items:
if j.rdtype == 1:
print (j.address)
区分工具difflib
（用在nginx的配置上，比较html上）
#!/usr/bin/python import difflib text1 = """text1: This module provides classes and functions for comparing sequences. including HTML and context and unified diffs. difflib document v7.4 add string """ text1_lines = text1.splitlines() text2 = """text2: This module provides classes and functions for Comparing sequences. including HTML and context and unified diffs. difflib document v7.5""" text2_lines = text2.splitlines() d = difflib.Differ() diff = d.compare(text1_lines, text2_lines) print '\n'.join(list(diff))
比较两个文件夹：filecmp
import filecmp a="/home/test/filecmp/dir1" b="/home/test/filecmp/dir2" dirobj=filecmp.dircmp(a,b,['test.py']) print "-------------------report---------------------" dirobj.report() print "-------------report_partial_closure-----------" dirobj.report_partial_closure() print "-------------report_full_closure--------------" dirobj.report_full_closure() print "left_list:"+ str(dirobj.left_list) print "right_list:"+ str(dirobj.right_list) print "common:"+ str(dirobj.common) print "left_only:"+ str(dirobj.left_only) print "right_only:"+ str(dirobj.right_only) print "common_dirs:"+ str(dirobj.common_dirs) print "common_files:"+ str(dirobj.common_files) print "common_funny:"+ str(dirobj.common_funny) print "same_file:"+ str(dirobj.same_files) print "diff_files:"+ str(dirobj.diff_files) print "funny_files:"+ str(dirobj.funny_files)
SMTPlib 自动发邮件给运维
