python文件操作的二个例子。
例1，python文件操作
复制代码 代码示例:
# cat main.py
#python2.7.3
#coding=utf8
import os
import sys
def sub_directory(path, old, new):
path_set = []
for dirpath, dirnames, filenames in os.walk(path):
for name in filenames:
full_path = os.path.join(dirpath, name)
full_path = full_path.replace(old, new)
path_set.append(full_path)
return path_set
if __name__ == "__main__":
print sub_directory(sys.argv[1], sys.argv[2], sys.argv[3])
例2，python文件操作。
复制代码 代码示例:
#!/bin/python
import os
properties = open("text.txt",'rb+')
lines = properties.readlines()
d=""
for line in lines:
c = line.replace("my name is abc", "my name is efg")
d += c
properties.seek(0) #不要让python记住执行到这里，从文件头还始
properties.truncate() #清空文件
properties.write(d)
properties.close()
