expression - python re.search error TypeError: expected string or buffer -

-

why 

re.search("\.docx", os.listdir(os.getcwd()))

yield following error?

typeerror: expected string or buffer

because os.listdir returns list re.search wants string.

the easiest way doing is:

[f f in os.listdir(os.getcwd()) if f.endswith('.docx')]

or even:

import glob glob.glob('*.docx')
