不太懂python 2。 在python 3中，父文件夹可以按如下方式添加:

import sys 
sys.path.append('..')

.．.然后我们可以从中导入模块

如果将模块文件夹添加到PYTHONPATH中失败，则可以修改sys. conf文件。Python解释器在你的程序中搜索要导入的模块的路径列表，Python文档说:

When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations: the directory containing the input script (or the current directory). PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH). the installation-dependent default. After initialization, Python programs can modify sys.path. The directory containing the script being run is placed at the beginning of the search path, ahead of the standard library path. This means that scripts in that directory will be loaded instead of modules of the same name in the library directory. This is an error unless the replacement is intended.

知道了这一点，你可以在程序中执行以下操作:

import sys
# Add the ptdraft folder path to the sys.path list
sys.path.append('/path/to/ptdraft/')

# Now you can import your module
from ptdraft import nib
# Or just
import ptdraft

这是对我来说最简单的解决方法:

from ptdraft import nib

与图书馆合作。 创建一个名为nib的库，使用setup.py安装它，让它驻留在站点包中，这样你的问题就解决了。 你不需要把你做的所有东西都装在一个包里。把它拆成碎片。

我建这个图书馆就是为了做这个。

# Just add parent path
add_parent_path(1)

# Append to syspath and delete when the exist of with statement.
with add_parent_path(1):
   # Import modules in the parent path
   pass
