I am writing code for AI chatbot in which I have to lemmatize words of data corpus
word_patterns = [lemmatizer.lemmatize(word.lower()) for word in word_patterns]
but it gives error like
Traceback (most recent call last):
word_patterns = [lemmatizer.lemmatize(word.lower()) for word in word_patterns]
AttributeError: 'list' object has no attribute 'lower'
How do I solve it??
I have no idea to resolve it

This is the part of code I am talking about:
while True:
print 'What is your age(only numeric):'
age = raw_input()
if age.isdigit():
break
print 'Please try again. We take only numeric value.'
When I replace isdigit with isdecimal, I get this error no matter what value i enter.
Traceback (most recent call last):
File "test.py", line 4, in <module>
if age.isdecimal():
AttributeError: 'str' object has no attribute 'isdecimal'
Although it runs fine with isdigit.
Also, when I replace raw_input with input, it give this error.
Traceback (most recent call last):
File "test.py", line 4, in <module>
if age.isdigit():
AttributeError: 'int' object has no attribute 'isdigit'
Am I doing something wrong which I am not able to catch? I am new to python and did my research about isdigit, is decimal, input and raw_input before putting down question here. It may be very minute error but I am not sure what is it.
For the first part:
In Python 2, isdecimal is a method of the unicode class, not of str (i.e. bytes). Hence:
>>> '3.2'.isdecimal()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'str' object has no attribute 'isdecimal'
>>> u'3.2'.isdecimal()
For the second part, input tries to guess what kind of input it gets, and will properly cast "1" into an int, while raw_input will always return the raw string. Since isdigit is a method defined in the str class, you get the error.
I am a newbie to python. Just try to get the comments defined in function using doc but getting the error.
Here's my code:
def nam(i):
"""passing the name to
a function"""
print('hello '+i+' good mornin')
And here's the error:
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
print(nam._doc_)
AttributeError: 'function' object has no attribute '_doc_'
Replace _doc_ (single underline on each side) with __doc__ (double underlines)
To illustrate, let's define your function and display the documentation:
>>> def nam(i):
... """passing the name to
... a function"""
... print('hello '+i+' good mornin')
...
>>> nam.__doc__
'passing the name to\n a function'
The method above works. The method below, however, fails:
>>> nam._doc_
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'function' object has no attribute '_doc_'
The reason is that __doc__ needs two underline characters on each side, not just one.
Documentation
From the python online documentation:
docstring A string literal which appears as the first expression
in a class, function or module. While ignored when the suite is
executed, it is recognized by the compiler and put into the __doc__
attribute of the enclosing class, function or module. Since it is
available via introspection, it is the canonical place for
documentation of the object.
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.

how can i fix this please ?
No Problem, I fixed it.I was using an older version of P4PYTHON module
