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

This logic will first convert the items in list to string(str). Sometimes the list contains a tuple like

alist = [(i12,tiger), 
(113,lion)]

This logic will write to file each tuple in a new line. We can later use eval while loading each tuple when reading the file:

outfile = open('outfile.txt', 'w') # open a file in write mode
for item in list_to_persistence:    # iterate over the list items
   outfile.write(str(item) + '\n') # write to the file
outfile.close()   # close the file
