【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：
