How do I find the modules in Tkinter?
The simplest approach is probably to explore your file system:
Step 1: where's Tkinter?
$ python -c 'import Tkinter, os; print os.path.dirname(Tkinter.__file__)'
/usr/lib/python2.6/lib-tk
I have tried # 1. with another command but all I get is an error messages.
$ python -c 'import time, os; print os.path.dirname(time.__doc__)' #
This one gave no output.
You typed time.__doc__ instead of time.__file__. With the latter you'd get
an AttributeError because the time module is implemented in C.
$ python -c 'import time, strftime, os; print
os.path.dirname(strftime.__doc__)'
Traceback (most recent call last):
File "<string>", line 1, in<module>
ImportError: No module named strftime
Well you cannot import a module that doesn't exist...
$ python -c 'import os; from time import strftime; print
os.path.dirname(strftime.__file__)'
Traceback (most recent call last):
File "<string>", line 1, in<module>
AttributeError: 'builtin_function_or_method' object has no attribute
'__file__'
$ python -c 'import time, os; print os.path.dirname(time.__file__)'
Traceback (most recent call last):
File "<string>", line 1, in<module>
File "/usr/lib/python2.6/posixpath.py", line 119, in dirname
i = p.rfind('/') + 1
AttributeError: 'NoneType' object has no attribute 'rfind'
$ python -c 'import time, os; print os.path.dirname(time.__package__)'
more errors
I am obviously doing something wrong.
The method to find the location of a module that I gave works only for
modules and only for modules implemented in Python. You can find both
functions and modules implemented in Python with inspect.getsourcefile():
from inspect import getsourcefile
import os
getsourcefile(os) # a module
'/usr/lib/python2.6/os.py'
getsourcefile(os.path) # another module with an interesting filename
'/usr/lib/python2.6/posixpath.py'
getsourcefile(os.walk) # a function implemented in Python
'/usr/lib/python2.6/os.py'
getsourcefile(os.mkdir) # a function implemented in C
Traceback (most recent call last):
File "<stdin>", line 1, in<module>
File "/usr/lib/python2.6/inspect.py", line 441, in getsourcefile
filename = getfile(object)
File "/usr/lib/python2.6/inspect.py", line 418, in getfile
raise TypeError('arg is not a module, class, method, '
TypeError: arg is not a module, class, method, function, traceback, frame,
or code object
