writing a list to a file

How do I write a list to a file, becuase I seem to not be able to do it?

NOTE: Be sure that the data in the list are strings, or make sure that you are writing strings to the file at least.

Here's an example:
============================

# Create a file object and open file
# create an empty list
# populate the list with numbers ranging 1..10
# convert number in list to strings
# write the list to a file
# close the file

#!/usr/bin/env python

myfile = open('myfile', 'w')
mylist = []
for x in range(1,11): mylist.append(x)
mylist = map(lambda(x): str(x), mylist)
myfile.writelines(mylist)
myfile.close()

=================================
