Okay, I solved my problem with Python finding modules:
I put the following into a file in my home directory, on the good advice of
Andrea Crotti:
import sys
sys.path.append('/home/foo/mypath'
I named the file "~/pypath.py", so now, in idle:
import pypath
No errors.
I'm still getting a little frustrated loading modules. I typed the following
little test function into idle:
def intersect(seq1,seq2):
res=[]
for x in seq1:
if x in seq2:
res.append(x)
return res
intersect('spam','spmmer')
No big deal. Runs fine. Exited and re-entered idle,
import pypath
import intersect #the name of a file that contains the above short function.
This imports the module 'intersect'. The name 'intersect' refers to the
module itself.
intersect('spam','spmmer')
This tries to call the module. Perhaps you meant:
intersect.intersect('spam','spmmer')
If you have a module "foo", which contains a function "bar", then "foo"
refers to the module and "foo.bar" refers to the function.
Traceback (most recent call last):
File "<pyshell#2>", line 1, in<module>
intersect('spam','spmmer')
TypeError: 'module' object is not callable
Huh? Why doesn't this run when imported? More importantly, how do I
interpret this error message so that I can find the problem myself next time?
