Count and replacing strings a texfile

[Greg Jorgensen]

Try this:

----
# read all text from the file
f = open(filename, "r")
s = f.read()
f.close()

# split text into a list at every occurence of %id%
t = s.split("%id%")
n = len(t)      # number of list elements
result = s[0]   # start with first element in list
# iterate over list, appending counter and next text chunk
for i in range(1,n):
        result += str(i) + s[i]

print "%s occurences replaced" % (n-1)
print result
