You are right. Here's my original code with your simple change and a
typo corrected:

===
# 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
r = [t[0]]       # start with first element in list
# iterate over list, inserting counter between elements
for i in range(1,n):
        r.append(str(i) + t[i])

result = ''.join(r)
print "%s occurences replaced" % (n-1)
print result
===
