如何在python中导入具有相同名称的多个文件

Question

I have following structure for a python project that generate source files:

/project_name/src/module_name0/scripts/generate.py
/project_name/src/module_name1/scripts/generate.py
...
/project_name/src/module_nameN/scripts/generate.py

I want use generate scripts from script located in:

/project_name/prj/generate_all.py

How may I import generate scripts from generate_all ? I tried to add /project_name/src/module_nameK to sys.path , but because the files have same name one of them hides the others. I don't want to add __init__.py file in module_nameK folders as I have only other source files there.

Take a look at the imp module.

EDIT

I think you need imp.load_source("somemodule.name", "full/path/to/your/module")

Your can use imp.load_module(name, ...)

An example taken from python docs:

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()

You can always try:

import xxx as yyy

So for example if you want to rename MySQLdb to something easier to type, you could write

import MySQLdb as mysql
