python操作文件，文件夹

获得目录下相关文件，文件夹信息

 

 

import os 
import os.path 
rootdir = "D:\\proclog\\loganalysis\\result\\bill" 
for parent, dirnames, filenames in os.walk(rootdir): 
#case 1: 
    for dirname in dirnames: 
        print "parent is:" + parent 
        print "dirname is:" + dirname 
#case 2 
    for filename in filenames: 
        print "parent is:" + parent 
        print "filename with full path :" + os.path.join(parent, filename) 
  

 

 

 

GZIP包处理gz压缩文件内容：

 

import gzip
f = gzip.open('/home/joe/file.txt.gz', 'rb')
file_content = f.read()
f.close()
Example of how to create a compressed GZIP file:

import gzip
content = "Lots of content here"
f = gzip.open('/home/joe/file.txt.gz', 'wb')
f.write(content)
f.close()
Example of how to GZIP compress an existing file:

import gzip
f_in = open('/home/joe/file.txt', 'rb')
f_out = gzip.open('/home/joe/file.txt.gz', 'wb')
f_out.writelines(f_in)
f_out.close()
f_in.close()

 

 

文件的读写：

 

#file write

#filename = "test.html"
# 
#print "Writing to file: %s" % filename
# 
# 
#file = open(filename, 'a')
# 
#file.write("This is the n撒旦法啊的ew content of test.txt :-)中文呢\n")
# 
#file.close()
    
#file_object = open('test.txt')
#try:
#    all_the_text = file_object.read()
#finally:
#    file_object.close()
#    
#for line in all_the_text.split('\n'):
#    print line
