Hi Mike,
Converting an (almost)arbitrary object into a string is what the Pickle
module does. CPickle is faster. Take a look into into it in the docs.
Here's an example:
import cPickle
lala = [1, 2, 3, 'four', 'V']
lala
[1, 2, 3, 'four', 'V']
fileo = open('lala.pkl', 'w')
yes it is...
convert list to string:
L = [1,2,3] L = [str(x) for x in L] s = string.join(L,' ') print len(s)
convert list to a file
myF = open(namaFile,w) for s in myList[:-1]: myF.write(str(s)+\n) myF.write(str(myList[len(myList)-1])) myF.close()
Cheers,
