inFridge.append("pickles")
print inFridge The output of my print command now displays:
['ketchup', 'mustard', 'relish', 'pickles'] That looks right, so I have my script repickle the inFridge list and add it to the file:
FILE = open("fridge.txt", 'w')
cPickle.dump(inFridge, FILE)
FILE.close()
To get my information out of the file and back into a useable list, I simply open the file for reading and use the cPickle.load command to unpickle it. For the purposes of demonstration, I've used a new variable, inFridgeFile, to store the results:
FILE = open("fridge.txt", 'r')
inFridgeFile = cPickle.load(FILE)
FILE.close()
print inFridgeFile The output of the print command displays:
['ketchup', 'mustard', 'relish', 'pickles'] When I repickled my list, cPickle recognised my original contents and didn't duplicate them. The inFridgeFile variable contains my information restored to its original list format. To put a lid on it
You have various options for serialising your data in Python, including pickle and cPickle. My cPickle example showed that this implementation is truly handy, especially since these commands will preserve your original object and allow modifications to be made even after it has been processed. This functionality will keep you from being stuck in a pickle next time you're saving or transmitting objects.
