比較使用python

Question

兩個文件的內容我有一個文件名exclusionlist.txt和我有內容像

  import os 
      import re 
      import subprocess 
      ......and many more 

我有另一個libraries.txt文件命名，該文件的內容是

  import mymodule 
     import empmodule,os 
     import subprocess 
     import datetime,logging,re 
     .......and many more 

我的問題是，從蟒蛇怎麼知道這是在exclusionlist.txt內容也出現在libraries.txt因爲這混亂了..

  f = open('exclusionlist.txt', 'r') 
     f.read() 

     f1= open('libraries.txt', 'r') 
     f1.read() 

     if (//Is contents of f1 present in f2): 
      print libraries found 
     else: 
      print not found 

     f.close() 
     f1.close()

使用交集：

def readImports(path): 
    with open(path) as f: 
     for line in f: 
      # lines of form "import ___,___" 
      # assuming not of form "from ___ import ___ [as ___]" 
      if 'import' in line: 
       modules = line.split('import')[1] 
       for module in modules.split(','): 
        yield module.strip() 

linesInExclusion = set(readImports('exclusionlist.txt')) 
linesInLibraries = set(readImports('libraries.txt')) 

print(linesInExclusion.intersection(linesInLibraries)) 

你可以做return (line.strip() for line in f if line.strip()!='')如果你想成爲完美...
