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()

下面是一些适用于所有Python版本的代码，从2.7-3.5到其他版本。

config_file = "/tmp/config.py"
with open(config_file) as f:
    code = compile(f.read(), config_file, 'exec')
    exec(code, globals(), locals())

我测试了它。它可能很难看，但到目前为止，它是唯一一个适用于所有版本的。

这应该行得通

path = os.path.join('./path/to/folder/with/py/files', '*.py')
for infile in glob.glob(path):
    basename = os.path.basename(infile)
    basename_without_extension = basename[:-3]

    # http://docs.python.org/library/imp.html?highlight=imp#module-imp
    imp.load_source(basename_without_extension, infile)

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

我认为，最好的方法是从官方文件（29.1。imp-访问导入内部构件）：

import imp
import sys

def __import__(name, globals=None, locals=None, fromlist=None):
    # Fast path: see if the module has already been imported.
    try:
        return sys.modules[name]
    except KeyError:
        pass

    # If any of the following calls raises an exception,
    # there's a problem we can't handle -- let the caller handle it.

    fp, pathname, description = imp.find_module(name)

    try:
        return imp.load_module(name, fp, pathname, description)
    finally:
        # Since we may exit via an exception, close fp explicitly.
        if fp:
            fp.close()

我发现这是一个简单的答案：

module = dict()

code = """
import json

def testhi() :
    return json.dumps({"key" : "value"}, indent = 4 )
"""

exec(code, module)
x = module['testhi']()
print(x)
