Recursive File Read, update

Wed, 06 Jan 2010 04:34:34 -0700

hi,

I am very new to python and thanks for your support.

I am trying to write a program to read all the .DAT files in the given folder and its sub folders.

Then in each of the .DAT file, I want to replace a perticular string - this string appears within first 10 lines in the file.

For example: The files have below string on line 4 or 7.
Name : TESTNAME

I want to update (append) the name with the filename. The output is like
Name : FILENAME_TESTNAME
(FILENAME is the name of the file without .DAT extension)

any help... thanks.

def get_file(dir):
return [name for name in os.listdir(dir)
if os.path.isfile(os.path.join(dir,name))]

if __name__=='__main__':
list=[]
list=get_immediate_subdirectories(os.getcwd())
print list
filelist=[]
for dir in list:
fileall=get_file(dir)
for file in fileall:
filename,extension=file.split('.')
if extension=='py':
filename+='__TESTNAME'
#filelist.append('in dir='+dir)
filelist.append(filename)
print filelist
