Thanks for your feedback. First of all, if you try to run yum install python27-devel, then you should get the message like this:
No package python27-devel available
Then I followed this link,
yum search python | grep -i devel
This will show you that you have python-devel.x86_64 package available if your OS is a 64 bit OS. If I am correct, then the following command should work fine as shown in the accepted answer:
yum install python-devel.x86_64
