Python Script locked for debug in VS 2015

I'm doing the nucleai courses. Exercises are based on python scripts and I'm using Visual Studio 2015. At some point, we have to use the library nltk. I was trying to debug some code I'm calling (I have the source) and something really weird happens: breakpoints work, but I can't use F10 to jump line to line. It just skips all the script. I can debug without any problem any of my scripts but not those within the library. So my question is: is there any option to "unlock" the script so I can debug line by line? I'm new with python and I can't find anything similar on google. I'm posting the code in case something is relevant. The function I want to debug is 'Respond'

from __future__ import print_function

import re
import random
from nltk import compat

reflections = {
"i am"       : "you are",
"i was"      : "you were",
"i"          : "you",
"i'm"        : "you are",
"i'd"        : "you would",
"i've"       : "you have",
"i'll"       : "you will",
"my"         : "your",
"you are"    : "I am",
"you were"   : "I was",
"you've"     : "I have",
"you'll"     : "I will",
"your"       : "my",
"yours"      : "mine",
"you"        : "me",
"me"         : "you"
}

class Chat(object):
def __init__(self, pairs, reflections={}):
    self._pairs = [(re.compile(x, re.IGNORECASE),y) for (x,y) in pairs]
    self._reflections = reflections
    self._regex = self._compile_reflections()


def _compile_reflections(self):
    sorted_refl = sorted(self._reflections.keys(), key=len,
            reverse=True)
    return  re.compile(r"\b({0})\b".format("|".join(map(re.escape,
        sorted_refl))), re.IGNORECASE)

def _substitute(self, str):
   return self._regex.sub(lambda mo:
            self._reflections[mo.string[mo.start():mo.end()]],
                str.lower())

def _wildcards(self, response, match):
    pos = response.find('%')
    while pos >= 0:
        num = int(response[pos+1:pos+2])
        response = response[:pos] + \
            self._substitute(match.group(num)) + \
            response[pos+2:]
        pos = response.find('%')
    return response

def respond(self, str):
    # check each pattern
    for (pattern, response) in self._pairs:
        match = pattern.match(str)

        # did the pattern match?
        if match:
            resp = random.choice(response)    # pick a random response
            resp = self._wildcards(resp, match) # process wildcards

            # fix munged punctuation at the end
            if resp[-2:] == '?.': resp = resp[:-2] + '.'
            if resp[-2:] == '??': resp = resp[:-2] + '?'
            return resp

# Hold a conversation with a chatbot
def converse(self, quit="quit"):
    input = ""
    while input != quit:
        input = quit
        try: input = compat.raw_input(">")
        except EOFError:
            print(input)
        if input:
            while input[-1] in "!.": input = input[:-1]
            print(self.respond(input))

Any help will be very much appreciated. Thanks.

EDIT: I solved my problem but I haven't found a solution for the question. I'm using PyCharm (as suggested in the first comment) and it works like a charm. I can debug everything without any problem now. No file modification at all. I'm inclined to think that this is a bug in Python tools for Visual Studio.

Other members also got the similar issue, my suggestion is that you can use the PyCharm instead of PTVS as a workaround. Of course, you could also start a discussion(Q AND A) from this site for PTVS tool:
