How can I fix this Qo-DL-Reborn error i tried reinstalling python and the error continues?

Traceback (most recent call last):
File "F:\GAMES-MOVIE-VIDEO-MUSIC COLLECTION [OPTICAL-DIGITAL]\DIGITAL COPIES\QOBUZ MUSIC\Qo-DL-Reborn\qo-dl_reborn.py", line 21, in
client = qopy.Client()

Python 2.7: Error not caught by exception due to "raise"

Here's my code:
import pandas as pd
df2 = pd.DataFrame()
try:
df_task = df_task.append(df2, ignore_index = True)
except NameError:
df_task = df2
raise
It produces this error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 540, in runfile
execfile(filename, namespace)
File "/home/cld_intern/.spyder2/.temp.py", line 12, in <module>
df_task = df_task.append(df2, ignore_index = True)
NameError: name 'df_task' is not defined
The except block is supposed to catch the NameError, but somehow the inclusion of "raise" without specifying the exception to raise produces a NameError. Why is it so?
This runs perfectly:
import pandas as pd
df2 = pd.DataFrame()
try:
df_task = df_task.append(df2, ignore_index = True)
except NameError:
df_task = df2
This runs as expected too:
import pandas as pd
df2 = pd.DataFrame()
try:
df_task = df_task.append(df2, ignore_index = True)
except NameError:
df_task = df2
raise Exception("error message")
With the following traceback:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/dist-packages/spyderlib/widgets/externalshell/sitecustomize.py", line 540, in runfile
execfile(filename, namespace)
File "/home/cld_intern/.spyder2/.temp.py", line 15, in <module>
raise Exception("error message")
Exception: error message

in python 3:
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
NameError: name 'df_task' is not defined
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 4, in <module>
NameError: name 'df2' is not defined
in python2.7
Traceback (most recent call last):
File "<stdin>", line 4, in <module>
NameError: name 'df2' is not defined
Are you sure you are using python 2.7?
Like mentioned in the comment, df2 is not defined i guess.

It says the 'self.workbook.close()' in del is wrong.
I don't understand.......
please help me !

Deep-learning library Neon DataIterator / ArrayIterator init error

When trying to set up the DataIterator as explained on neon tutorial.
from neon.data import DataIterator
import numpy as np
X = np.random.rand(10000, 3072)
y = np.random.randint(1, 11, 10000)
train = DataIterator(X=X, y=y, nclass=10, lshape=(3, 32, 32))
I encountered a weird error:
ERROR:neon.data.dataiterator:DataIterator class has been deprecated and renamed"ArrayIterator" please use that name.
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "neon/data/dataiterator.py", line 168, in __init__
super(DataIterator, self).__init__(*args, **kwargs)
File "neon/data/dataiterator.py", line 82, in __init__
self.Xdev = [self.be.array(x) for x in X]
AttributeError: 'NoneType' object has no attribute 'array'
I then tried with ArrayIterator, keeping X, y the same.
ArrayIterator(X=X, y=y, nclass=10, lshape=(3,32,32))
With the same NoneType error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "neon/data/dataiterator.py", line 82, in __init__
self.Xdev = [self.be.array(x) for x in X]
AttributeError: 'NoneType' object has no attribute 'array'
Why would this be the case? Is there an easy fix?

Fixed the problem by generating backend.
from neon.backends import gen_backend
be = gen_backend()

How to print the first line from a traceback stack

Suppose I am given the following traceback:
Traceback (most recent call last):
File "<wingdb_compile>", line 3, in <module>
File "C:\Python34\lib\ftplib.py", line 419, in login
resp = self.sendcmd('PASS ' + passwd)
File "C:\Python34\lib\ftplib.py", line 272, in sendcmd
return self.getresp()
File "C:\Python34\lib\ftplib.py", line 245, in getresp
raise error_perm(resp)
ftplib.error_perm: 530 Login incorrect.
I have managed to extract the Error details but what has stumped me is how would I extract the line:
File "<wingdb_compile>", line 3, in <module>
I was looking at methods in the trace back package but wondered if any one had experience with that here

The function traceback.format_exc is built primarily for this
This is like print_exc(limit) but returns a string instead of printing to a file.
>>> import traceback
>>> try:
... x = 2/0
... except:
... error = traceback.format_exc()
...
>>> error
'Traceback (most recent call last):\n File "<stdin>", line 2, in <module>\nZeroDivisionError: division by zero\n'
>>> linesoferror = error.split('\n')
>>> linesoferror
['Traceback (most recent call last):', ' File "<stdin>", line 2, in <module>', 'ZeroDivisionError: division by zero', '']
So now you wanted the first line then you can simply use
>>> linesoferror[1]
' File "<stdin>", line 2, in <module>'
Voila! You have what you want
