NLTK Tokenize: Tokenize a twitter text
NLTK Tokenize: Exercise-6 with Solution
Write a Python NLTK program to tokenize a twitter text.
Sample Solution:
Python Code :
from nltk.tokenize import TweetTokenizer
tknzr = TweetTokenizer(strip_handles=True, reduce_len=True)
tweet_text = "NoSQL introduction - w3resource https://bit.ly/1ngHC5F #nosql #database #webdev"
print("\nOriginal Tweet:")
print(tweet_text)
result = tknzr.tokenize(tweet_text)
print("\nTokenize a twitter text:")
print(result)
Sample Output:
Original Tweet: NoSQL introduction - w3resource https://bit.ly/1ngHC5F #nosql #database #webdev Tokenize a twitter text: ['NoSQL', 'introduction', '-', 'w3resource', 'https://bit.ly/1ngHC5F', '#nosql', '#database', '#webdev']

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
