Hello everyone,

When I try and run the following code

import glob, operator

fpout = open("result.dat","w")

for path in glob.glob("*.txt"):
    with open(path, "r") as fp:
        fields = [ line.split(" ") for line in fp ]
        maxline = " ".join(max(fields, key = lambda row: float(row[5]))
        print >> fpout, maxline

I get the error:

 File "findmaxvalue.py", line 9
    print >> fpout, maxline
        ^
SyntaxError: invalid syntax

Does anyone with experience with python know how to fix it?

If details on the function help: I am reading into a group of files in a directory and asking what is the highest integer value in column 5. The row containing this value is then to be printed to a new output file, containing the row with the highest value from each input file. It's to help with some population genetic analyses.

All help greatly appreciated, Thanks!
