Python NLTK | tokenize.regexp()

With the help of NLTK tokenize.regexp() module, we are able to extract the tokens from string by using regular expression with RegexpTokenizer() method.

Syntax : tokenize.RegexpTokenizer()
Return : Return array of tokens using regular expression

Example #1 :
In this example we are using RegexpTokenizer() method to extract the stream of tokens with the help of regular expressions.

# import RegexpTokenizer() method from nltk
from nltk.tokenize import RegexpTokenizer

# Create a reference variable for Class RegexpTokenizer
tk = RegexpTokenizer('\s+', gaps = True)

# Create a string input
gfg = "I love Python"

# Use tokenize method
geek = tk.tokenize(gfg)

print(geek)

Output :

[‘I’, ‘love’, ‘Python’]

Example #2 :

# import RegexpTokenizer() method from nltk
from nltk.tokenize import RegexpTokenizer

# Create a reference variable for Class RegexpTokenizer
tk = RegexpTokenizer('\s+', gaps = True)

# Create a string input
gfg = "Geeks for Geeks"

# Use tokenize method
geek = tk.tokenize(gfg)

print(geek)

Output :

[‘Geeks’, ‘for’, ‘Geeks’]
