Hey, I keep getting the error above and unfortunately browsing through google and finding similar responses has not been fruitful for me. My code is below and I have marked off the location of the problem in my code. I'm wondering the following:
1) Doesn't the read() file object method return the specified characters from the file as a string? 2) If #1 is correct, then why is my variable "source" being viewed as a list as opposed to a string? 3) How can I change my variable "source" so that it can use the 'find' method? Or alternatively, is there another method besides the 'find' method that would do the same thing that 'find' does that would work on my variable 'source' as it currently is? Thanks so much, Ben #recursively find each instance of the tag throughout the whole document def findOneTag (tag, source, output): print("tag is ", tag) #print("source is now ", source) print("output is ", output) #base case if source == "": return #recursive case tagIndex = source.find(tag) #(*********THIS IS THE LOCATION OF THE PROBLEM**********) print("tagIndex is ", tagIndex) start = source[tagIndex:].find("\t") + 1 print("start is ", start) stop = source[tagIndex + start:].find("\t") print("stop is ", stop) if tagIndex !=-1: output.write(tag + "\t" + line[start: stop]) print("spliced text is: ", line[start:stop]) #recursively call findOneTag(tag, String source[stop:], output) findOneTag(tag, source[stop + 1:], output) def main(): tag = "species" inname = "skeletontext.txt" outname = "skeletontext1234567.txt" inname1 = open(inname, "r") output = open(outname, "w") source = inname1.readlines() print("source is: ", source) findOneTag(tag, source, output) _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
