Yes, open a new file and write the string using the write() method. You can 
use string formatting to build the filename, too:

text = ... # the string you want to write 

nnn = raw_input("What is the serial number of the site? ")
brand = raw_input("What is the brand, or product name? ")

filename = "{NNN}{BRAND}_farm.any".format(BRAND=brand, NNN=nnn)
with open(filename, "w") as outstream:
    outstream.write(text)
