Hi,
As Adrian says, this is a problem with integer division. Before Spyder
2.3.0 we ran this command when creating a console
from __future__ import division
which changed integer to float division, and that's the source of the
issue you're seeing.
So a simple update to this new version will fix the problem.
Cheers,
Carlos

Hi Adrian,
Thanks for the quick reply.
I am running this only in one version of python. Python version 2.7.6.
I using SPYDER 2.2.5 that came with python(x,y) version 2.7.6.1. My
operating system is windows 7, 64bit.
I didn't run this code on different version of python.
The goal of this script is just to create 100 new folders.
I also import:
from brian import *
from numpy import *
Do you think it has something there that interfere with SPYDER?
As I mentioned before, SPYDER manages to create 100 folders ONLY if I
copy the code to the console. SPYDER creates just 4 folders when I run
the code in a new dedicated python interpreter. Try to run the code
(with the additional imports) and see for yourself. I can work with
this bug, but it is not very convenient.
Best,
Gilad

Hi,
I found a bug in SPYDER when trying to create new folders
within two
"for loops".
My code is:
import os
path=os.getcwd()
for modularity in xrange(0,26):
m=modularity/100
for part in xrange(1,5):
os.chdir(path)
exec("new_folder = '\mod%s_part%s'" % (m,part))
new_path=path + new_folder
if not os.path.exists(new_path):
os.makedirs(new_path)
os.chdir(new_path)
If I copy this to the console, the code works just fine, it
creates 100
(25*4) new folders.
However, if I run this code in a new dedicated python
interpreter, only
4 new folders are created.
Can anyone else verify this bug? I am using Spyder 2.2.5 that
came with
my python(x,y) version 2.7.6.1.
Are you running this in different versions of Python?
Or is there more to this code?
Because:
for modularity in xrange(0,26):
m=modularity/100
print m, modularity
0 0
0 1
0 2
0 3
0 4
0 5
0 6
0 7
0 8
0 9
0 10
0 11
0 12
0 13
0 14
0 15
0 16
0 17
0 18
0 19
0 20
0 21
0 22
0 23
0 24
0 25
Seems you are dealing with integer division. So either the case that
works is running in Python 3+ or you are doing a from __future__
import
division somewhere.
Best,
GIlad
