from nltk.parse.corenlp import CoreNLPServer
server = CoreNLPServer()
server.start()
When I run the above code, I'm getting the following error.
Traceback (most recent call last):

subprocess.devnull is new in Python 3.3.
Make sure you use a version of nltk which stil supports Python 2.7. From their changelog:
Version 3.5 2019-10-16
* drop support for Python 2
I often think it would be nice to have the following work even if the original object is a list... Is there a reason why this functionality is not implemented (in python 2.7)?
Example:
>>> a = [1,2,3,4]
>>> a.tolist()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'list' object has no attribute 'tolist'
How can I solve this problem?
def median(lst):
lst_s=lst.sort()
k=len(lst)
if k%2==0:
return ((lst_s[k/2]+lst_s[k/2-1])/2)
elif k%2==1:
return (lst_s[k/2-1/2])
res = median([1,2,3,7,6,5])
print('median:',res)
when I run this, it says
Traceback (most recent call last):
File "E:\lab5_p4_2015123176.py", line 13, in <module>
res = median([1,2,3,7,6,5])
File "E:\lab5_p4_2015123176.py", line 7, in median
return ((lst_s[k/2]+lst_s[k/2-1])/2)
TypeError: 'NoneType' object is not subscriptable
The problem is that list.sort() sorts the items of the list in place thus returns None. In your median function you need to replace lst_s = lst.sort() by lst_s = sorted(lst) if you don't want to modify element order in the original list.
