1.the use of ‘with open... as ...‘

2.the use of pickle(dump and load)

for Step1:

the ‘with open ... as...‘ is the short format of ‘try...except...finally‘

for Step2:

you can store a list with pickle.dump() and get the content again with pickle.load()

 1 >>> import pickle 2 >>> with open(‘test.pickle‘,‘wb‘) as data: 3     pickle.dump([‘a‘,‘2‘,‘et‘],data) 4  5      6 >>> with open(‘test.pickle‘,‘rb‘) as readFile: 7     the_list = pickle.load(readFile) 8  9     10 >>> the_list11 [‘a‘, ‘2‘, ‘et‘]12 >>> 

when use this method, you should be care with the encoding of file, like ‘wb‘,‘rb‘
