Python中二进制文件的读与写

import pickle as p

shoplistfile='shoplist.data'

shoplist=['apple','carrot']

# because the dump operation is using binary, so 'b' is needed.

# also for read file.

f=open(shoplistfile,'wb')

p.dump(shoplist,f)

f.close

del shoplist

f=open(shoplistfile,'rb')

storedlist=p.load(f)

print(storedlist)
