Writing a list to a file with Python

Question

Is this the cleanest way to write a list to a file, since writelines() doesn\'t insert newline characters?

file.writelines([\"%s\\n\" % item  fo         


        

Answer 1

Yet another way. Serialize to json using simplejson (included as json in python 2.6):

>>> import simplejson
>>> f = open('output.txt', 'w')
>>> simplejson.dump([1,2,3,4], f)
>>> f.close()

If you examine output.txt:

[1, 2, 3, 4]

This is useful because the syntax is pythonic, it's human readable, and it can be read by other programs in other languages.
