Iterate file name with counter
===

I'm splitting a file based on a string, and would like to have the output file names be numbered. 

This is what I have so far:

    outputfile = open("output.seq")   
    outputfileContent = outputfile.read()
    outputfileList = outputfileContent.split(">")
    for count, line in enumerate(f):
        for items in outputfileList:
            seqInfoFile = open('%f.dat', 'w')
        seqInfoFile.write(str(items))

I'm not sure where to define f. 

Thanks for any help!
