[Tutor] Files, directories and syntax

[Karen Windus]

Hi -

I'm somewhat new to python. I am trying to change a line in every html
file in a directory if there is a match on the text string I'm searching
for.  So I'm using glob to match a file pattern.  Then I want to loop
through every file, loop through every line, so a search on the regexp
that I've set up and if there is a match, at this point, I just would be
happy with printing out some debugging code and then closing (and
eventaully saving) the file.

When I run the following code now, I get a syntax error on  'file =
open(i,"rw")'   

I guess I'm not sure how to populate the file object (when I try and OPEN
a file in other words) with the actual name of the file.  So I'm using i
in a loop.  Is that wrong? In other languages that would work I
think.  Anyway, I don't know if I'm on the right track or not. 

 Here's what I have so far:

#! /usr/bin/env python 
def change_lines(directory = None): 
import glob,re 
result = [] 
filepattern = '*.{html}' 
filelist = glob.glob1(directory,filepattern)  
regexp = re.compile(r"Your Turn")  
for i in filelist:  
file=open(i,"rw")  
print "We opened a file"  
	for file in filelist:  
	lines = filenames.readlines()  
		for line in lines:  
		result = regexp.search(line)  
			if result == None:  
			print "Result was equal to None"  
			elif 'Your' in line or 'Turn' in line:  
			print "we had a match"  
			print result 
			else:  print "Nothing happened"  
return result
file.close() 

change_lines()


Thanks,

Karen
