我建这个图书馆就是为了做这个。

https://github.com/fx-kirin/add_parent_path

# 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

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

下面是一个更通用的解决方案，它将父目录包含到sys. conf中。路径(适用于我):

import os.path, sys
sys.path.append(os.path.join(os.path.dirname(os.path.realpath(__file__)), os.pardir))

在我看来，你并不真的需要导入父模块。让我们假设在nib.py中有func1()和data1，你需要在life.py中使用

nib.py

import simulations.life.life as life
def func1():
   pass
data1 = {}
life.share(func1, data1)

life.py

func1 = data1 = None

def share(*args):
   global func1, data1
   func1, data1 = args

现在您可以访问life.py中的func1和data。当然，在尝试使用它们之前，你必须小心地在life.py中填充它们，

虽然原作者可能不再寻找解决方案，但为了完整，有一个简单的解决方案。它是像这样运行life.py模块:

cd ptdraft
python -m simulations.life.life

通过这种方式，您可以从nib.py导入任何东西，因为ptdraft目录在路径中。
