If your function write_something_to_log is in file myfunctions.py you
can just do:
from myfunctions import write_something_to_log

and then use write_something_to_log() just like it was defined in that file.

Example:
#file: test1.py
def spam():
	print "Spam, eggs, and toast"

#file: myscript.py
from test1 import spam
spam()
#prints "Spam, eggs, and toast"

Hope this helps!
