error in maf-convert script

I want to convert my maf file to a sam file, i used the maf-convert.py like:

**python maf-convert.py sam Thal.maf > ThalLast.sam**

This is the error I am getting:

Fil**e "maf-convert.py", line 108
    print joined(outWords, " ")
               ^
SyntaxError: invalid syntax**

Can you help me troubleshoot it.
