Basically there is a file called
8puzzle.py and I want to import the file into another file (in the same folder and I cannot change the file name as the file is provided). Is there anyway to do this in Python? I tried usual way
from 8puzzle import *, it gives me an error.
import 8puzzle File "<input>", line 1 import 8puzzle ^ SyntaxError: invalid syntax
You could do
puzzle = __import__('8puzzle')
Very interesting problem. I’ll remember not to name anything with a number.
If you’d like to
import * — you should check out this question and answer.
The above answers are correct, but as for now, the recommended way is to use
Import a module. The name
argument specifies what module to import in absolute or relative terms
..mod). If the name is specified in relative
terms, then the package argument must be set to the name of the
package which is to act as the anchor for resolving the package name
import_module('..mod', 'pkg.subpkg')will import
The import_module() function acts as a simplifying wrapper around
importlib.__import__(). This means all semantics of the function are
importlib.__import__(). The most important difference
between these two functions is that
specified package or module (e.g.
the top-level package or module (e.g.
If you are dynamically importing a module that was created since the
interpreter began execution (e.g., created a Python source file), you
may need to call
invalidate_caches()in order for the new module to be
noticed by the import system.
__import__ is not recommended now.
importlib.__import__(name, globals=None, locals=None, fromlist=(), level=0)
An implementation of the built-in
Note Programmatic importing of modules should use
import_module()instead of this function.
Don’t use the
.py extension in your imports.
from 8puzzle import * work?
For what it’s worth,
from x import * is not a preferred Python pattern, as it bleeds that module’s namespace into your current context.
In general, try to import things you specifically want from that module. Any global from the other module can be imported.
e.g., if you have
8puzzle.foo you could do `from 8puzzle import
.py message is correct, it isn’t sufficient.
The other poster’s
__import__('8puzzle') suggestion is correct. However, I highly recommend avoiding this pattern.
For one, it’s reserved an internal, private Python method. You are basically breaking the fundamental assumptions of what it means to be able to import a module. Simply renaming the file to something else, like
puzzle8, will remedy this.
This will frustrate the hell out of experienced Python programmers who are expecting to know what your imports are at the top and are expecting code to (try to) conform to PEP8.
