I'm relative new to python and I puzzled by the following strange (to
me) behavior. I was taking pieces from two old scripts to build a new
one. When I began to debug it I got the following error message:
Traceback (most recent call last):
File
"/Users/williamminer/ex2gen/ex2gen-3.0.5/src/ScriptDev/run_ex2gen_scan.py",
line 38, in <module>
if re.search('varm',line):
AttributeError: 'function' object has no attribute 'search'
This had worked in the previous script but not the new one. I noticed
that the new script had an additional line at the beginning (line 3)
#!/usr/bin/env python
import sys, math, os, shutil, commands, re, mpmath
from mpmath import *
When I deleted this line, the script ran. Why did the line
from mpmath import *
Just a guess, (since I don;t have mpmath on hand), but if mpmath has a
definition for something named re, it would overwrite any previous
definition of re.
So general advice says don't use the "from xxx import *" unless you
really *know* what is in the module, and need *all* of it imported.
Either:
from mpmath import x,y,z,whatever
or
import re
import mpmath
... re.search ...
... mpmath.whatever ...

Trash the search function fro the regular expression module?
I'm running Python 2.6.2 on Mac running OS 10.6.3.
Thanks!
