这将允许在3.4中导入编译的（pyd）Python模块：

import sys
import importlib.machinery

def load_module(name, filename):
    # If the Loader finds the module name in this list it will use
    # module_name.__file__ instead so we need to delete it here
    if name in sys.modules:
        del sys.modules[name]
    loader = importlib.machinery.ExtensionFileLoader(name, filename)
    module = loader.load_module()
    locals()[name] = module
    globals()[name] = module

load_module('something', r'C:\Path\To\something.pyd')
something.do_something()

这将允许在3.4中导入编译的（pyd）Python模块：

import sys
import importlib.machinery

def load_module(name, filename):
    # If the Loader finds the module name in this list it will use
    # module_name.__file__ instead so we need to delete it here
    if name in sys.modules:
        del sys.modules[name]
    loader = importlib.machinery.ExtensionFileLoader(name, filename)
    module = loader.load_module()
    locals()[name] = module
    globals()[name] = module

load_module('something', r'C:\Path\To\something.pyd')
something.do_something()

你的意思是装货还是进口？

您可以操作sys.path列表，指定模块的路径，然后导入模块。例如，给定位于以下位置的模块：

/foo/bar.py

你可以这样做：

import sys
sys.path[0:0] = ['/foo'] # Puts the /foo directory at the start of your path
import bar

我给你做了一个用小鬼的包裹。我称之为import_file，它的用法如下：

>>>from import_file import import_file
>>>mylib = import_file('c:\\mylib.py')
>>>another = import_file('relative_subdir/another.py')

您可以通过以下方式获取：

如果我们在同一个项目中有脚本，但在不同的目录方式中，我们可以通过以下方法解决这个问题。

在这种情况下，utils.py位于src/main/util中/

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

import src.main.util.utils
#or
from src.main.util.utils import json_converter # json_converter is example method
