You can create a simple log file by,

Opening a file at a known location with proper access mode e.g. filehandle = open(Logfilefullpath, "a+") - Opening in append mode.
Use the write function to log your required information to the file. e.g. filehandle.write("sum function... ")
Close the filehandle to release the file. e.g. filehandle.close()
