Python逐行读取文件内容（Python read file line by line）

Python逐行读取文件内容
thefile= open("foo.txt")             
line = thefile.readline()            
while line:
    print line,                    
　　line = thefile.readline()
thefile.close()


Windows下文件路径的写法：
E:/codes/tions.txt


写文件：
thefile= open("foo.txt", "rw+")
for item in thelist:
  thefile.write("%s\n"% item)
thefile.close()
