【原】Python 用例：二进制写入和读取文件内容

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)

1.二进制文件，用NotePad++打开乱码

2.读取内容后，打印：
