As per the comments from @Ab it works.

But why I need to import sys ?

Answer 1

You can run import sys ; sys.path import sys ; sys.path and see if c:\\python27\\lib\\site-packages\\ is in your path list. If it is, then again try run from xlwt import easyxf

Answer 2

You clearly don't have xlwt installed, or Python doesn't know that you do.

Try running pip install xlwt .

You can also look to see where physically the code for xlwt is, and then add that file directory to your PYTHONPATH so that Python will know to look there for the module.

This could be because you're running your code from a virtualenv that does not have xlwt installed.
