Part 1 walks the directory. Part 2 extracts the text I want. Each part works fine independently but all together it gives an error . I tried the code below but I get an unexpected indent error at the line starting: with open (fname)

import os
import re

#walk the directory ree
rootDir = '.'
for dirName, subdirList, fileList in os.walk(rootDir):
    print('Found directory: %s' % dirName)
    for fname in fileList:
        print('\t%s' % fname)

#extract the text from each file
	    with open(fname) as infile, open('out.txt', 'a') as outfile:
	        full=infile.read().replace('\n','')
		    text = ''.join(re.findall(r"START(.+?)END", full))
		    outfile.write(text)
		    infile.close()
		    outfile.close()
