Exception TypeError when running a script more than once

[andres333]

Hi,

I have an error message when i run a script more than once.

Here the script, as simple as it could be:

# -*- coding: utf-8 -*-
import sys
import os
import matplotlib.pyplot as plt
import pyzdde.zdde as pyz

ln = pyz.createLink()
print(ln.zGetVersion()) # example
ln.close()

And here what is printed in a freshly started iPython console. Two runs are shown:

Python 2.7.11 |Anaconda 4.0.0 (64-bit)| (default, Feb 16 2016, 09:58:36) [MSC v.1500 64 bit (AMD64)]

As you can see, I am using Anaconda, Python 2.7, Spyder.

Interestingly this does not happen the first time that I run the code.

I have tried to follow the recommendations in earlier posts ( #40) but it does not seem to have an effect.

I would appreciate any suggestions.

All the best,
andres

I'm not sure what's going on.

Please try running the script in a "dedicated Python console" in spyder [Preferences >> Run >> Console >> Execute in a new dedicated Python console] and see if you can still reproduce the error.

Please do let me know.

Thank you,
Best regards,
Indranil.

Hi Indranil, sorry for the delay.

In a dedicated console this error does not appear. Also, the first time i run it in a non-dedicated console, it does not appear, only from the second time on. that may be the reason why it does not appear on a dedicated console.

Best & thanks.
