如何将某个对象"挑选"到某个目录？

Question

通常,执行以下代码会将对象pickle到我的current目录中的文件:

fp = open('somefile.txt', 'wb')
pickle.dump(object, fp)

如何将输出重定向pickle.dump到其他目录？

Answer 1

with open('/full/path/to/file', 'wb') as f:
    pickle.dump(object, f)

Answer 2

把pathlib和with结合起来怎么样，我觉得更灵活，更安全。

# from python 3.4
from pathlib import Path
my_path = Path("{path to you want to set root like . or ~}") / "path" / "to" / "file"
with my_path.open('wb') as fp:
    pickle.dump(object, fp)
