Getting file path of imported module
PythonPython Problem Overview
How can I get the file path of a module imported in python. I am using Linux (if it matters).
Eg: if I am in my home dir and import a module, it should return back the full path of my home directory.
Python Solutions
Solution 1 - Python
Modules and packages have a __file__ attribute that has its path information. If the module was imported relative to current working directory, you'll probably want to get its absolute path.
import os.path
import my_module
print(os.path.abspath(my_module.__file__))
Solution 2 - Python
I've been using this:
import inspect
import os
class DummyClass: pass
print os.path.dirname(os.path.abspath(inspect.getsourcefile(DummyClass))
(Edit: This is a "where am I" function - it returns the directory containing the current module. I'm not quite sure if that's what you want).
Solution 3 - Python
This will give you the directory the module is in:
import foo
os.path.dirname(foo.__file__)
Solution 4 - Python
I could be late here, some of the modules would throw AttributeError when using __file__ attribute to find the path. In those case one can use __path__ to get the path of the module.
>>> import some_module
>>> somemodule.__path__
['/usr/lib64/python2.7/site-packages/somemodule']
Solution 5 - Python
To find the load path of modules already loaded:
>>> import sys
>>> sys.modules['os']
<module 'os' from 'c:\Python26\lib\os.pyc'>
Solution 6 - Python
I have been using this method, which applies to both non-built-in and built-in modules:
def showModulePath(module):
if (hasattr(module, '__name__') is False):
print 'Error: ' + str(module) + ' is not a module object.'
return None
moduleName = module.__name__
modulePath = None
if imp.is_builtin(moduleName):
modulePath = sys.modules[moduleName];
else:
modulePath = inspect.getsourcefile(module)
modulePath = '<module \'' + moduleName + '\' from \'' + modulePath + 'c\'>'
print modulePath
return modulePath
Example:
Utils.showModulePath(os)
Utils.showModulePath(cPickle)
Result:
<module 'os' from 'C:\SciSoft\WinPython-64bit-2.7.10.3\python-2.7.10.amd64\lib\os.pyc'>
<module 'cPickle' (built-in)>
Solution 7 - Python
Try:
> help('xxx')
For example
>>> help(semanage)
Help on module semanage:
NAME
semanage
FILE
/usr/lib64/python2.7/site-packages/semanage.py
