[Albert]

I download the open source Python-2.1.3 from Python home page. My
platform is RedHat 7.2 .After uncompress, I type " python setup
install" The following word displayed :
File "setup.py", line 57
extlist = [ext for ext in extlist if ext.name == modname]
^
SyntaxError : invalid syntax

how to solve it?
