[python] How to import module when module name has a '-' dash or hyphen in it?

I want to import foo-bar.py. This works:

foobar = __import__("foo-bar")

This does not:

from "foo-bar" import *

My question: Is there any way that I can use the above format i.e., from "foo-bar" import * to import a module that has a - in it?

Starting from Python 3.1, you can use importlib :

import importlib  
foobar = importlib.import_module("foo-bar")

( https://docs.python.org/3/library/importlib.html )

If you can't rename the original file, you could also use a symlink:

ln -s foo-bar.py foo_bar.py

Then you can just:

from foo_bar import *

If you can't rename the module to match Python naming conventions, create a new module to act as an intermediary:

 ---- foo_proxy.py ----
 tmp = __import__('foo-bar')
 globals().update(vars(tmp))

 ---- main.py ----
 from foo_proxy import * 

Like other said you can't use the "-" in python naming, there are many workarounds, one such workaround which would be useful if you had to add multiple modules from a path is using sys.path

For example if your structure is like this:

foo-bar
+-- barfoo.py
+-- __init__.py

import sys
sys.path.append('foo-bar')

import barfoo
