Once foo.bar has been imported, the final traversal will call mpf.find_spec("foo.bar.baz", foo.bar.__path__, None). The PYTHONPATH is a list of directories for your computer to check whenever you type import MyModule into the interpreter. It also off-loads most of the boilerplate responsibilities of loaders back onto the import machinery. If __path__ is not empty, it must produce strings when iterated over. check over here
Why are wavelengths shorter than visible light neglected by new telescopes?

For importing, it does not matter, that the importing and and imported files share a directory. As a meta path finder, the path based finder implements the find_spec() protocol previously described, however it exposes additional hooks that can be used to customize how modules are found So now your path is updated but this is only the path to your master Python folder. Consider a simple package layout like the following (I typically use package layouts along these lines in my own projects - a lot of people hate nesting tests inside package directories

To selectively prevent import of some modules from a hook early on the meta path (rather than disabling the standard import system entirely), it is sufficient to raise ImportError directly Import Error Python No Module Named It is also appropriate to set __cached__ when __file__ is not set.

See Porting Python code for more details. http://stackoverflow.com/questions/33862963/python-cant-find-my-module IPython will look for modules to import that are not only found in your sys.path, but also on your current working directory.
First, find where the site module code lives: > import site > site.__file__ '/usr/lib/python2.7/site.pyc' Here is an excerpt from Ubuntu Python's site.py, which I peeked by opening /usr/lib/python2.7/site.py in a text Importerror Python Cannot Import Name The following sections describe the protocol for finders and loaders in more detail, including how you can create and register new ones to extend the import machinery. importlib Base classes and other tools for creating custom importers. Module loaders may opt in to creating the module object during loading by implementing a create_module() method.

In your case I presume you've installed py2neo using pip or another similar way, so Python doesn't need PYTHONPATH; but mypy doesn't know what Python 2's sys.path looks like (nor should Join them; it only takes a minute: Sign up Python cant find module in the same folder up vote 7 down vote favorite 2 My python somehow cant find any modules this content Any module already in the sys.modules cache, and any module that was successfully loaded as a side-effect, must remain in the cache.

How did you install python? This is just not how it's supposed to be used. See PEP 366 for further details. have a peek at these guys Loading¶ If and when a module spec is found, the import machinery will use it (and the loader it contains) when loading the module.
These strategies can be modified and extended by using various hooks described in the sections below. As noted elsewhere, the __main__ module is directly initialized at interpreter startup, much like sys and builtins. Show that the square matrix A is invertible Why do languages require parenthesis around expressions when used with "if" and "while"? When does TNG take place in relation to DS9?
Keep those puppies in their warm, snuggly project subdirectories. When calling __import__() as part of an import statement, the standard builtin __import__() is called. Packages 5.2.1. When I run the .py file I get the 'No Module' error for the widget.
Assuming your PYTHONPATH environment variable is not set, sys.path will consist of the current working directory plus any manipulations made to it by the site module. The site module is automatically imported when you start Python, you can read more about how it manipulates your sys.path in the Python docs. I created the _init_.py as an empty file and it worked for me. This is implementation-specific behavior that is not guaranteed to work in other Python implementations. In legacy code, it is possible to find instances of imp.NullImporter in the sys.path_importer_cache.
The one exception is __main__, where __spec__ is set to None in some cases. The value must be iterable, but may be empty if __path__ has no further significance.
