python 文件大小

1. os.path.getsize(file_path)：file_path为文件路径

  

   

    

     

    
    

     

      import os
     
    
   

    

     

    
    

     

      os.path.getsize('d:/svn/bin/SciLexer.dll')
     
    
   

    

     

    
    

     

      #1479904
     
    
  
 

2. 遍历文件夹，将所有文件大小加和， os.walk()遍历文件夹

  

   

    

     

    
    

     

      import os
     
    
   

    

     

    
    

     

      from os.path import join, getsize
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      def getdirsize(dir):
     
    
   

    

     

    
    

     

       size = 0
     
    
   

    

     

    
    

     
 for root, dirs, files in os.walk(dir):
     
    
   

    

     

    
    

     

       size += sum([getsize(join(root, name)) for name in files])
     
    
   

    

     

    
    

     
 return size
     
    
  
 

2.将文件大小进行格式化

  

   

    

     

    
    

     

      def size_format(size):
     
    
   

    

     

    
    

     
 if size < 1000:
     
    
   

    

     

    
    

     
 return '%i' % size + 'size'
     
    
   

    

     

    
    

     
 elif 1000 <= size < 1000000:
     
    
   

    

     

    
    

     
 return '%.1f' % float(size/1000) + 'KB'
     
    
   

    

     

    
    

     
 elif 1000000 <= size < 1000000000:
     
    
   

    

     

    
    

     
 return '%.1f' % float(size/1000000) + 'MB'
     
    
   

    

     

    
    

     
 elif 1000000000 <= size < 1000000000000:
     
    
   

    

     

    
    

     
 return '%.1f' % float(size/1000000000) + 'GB'
     
    
   

    

     

    
    

     
 elif 1000000000000 <= size:
     
    
   

    

     

    
    

     
 return '%.1f' % float(size/1000000000000) + 'TB'
