🛠️ Installation

To use word2num, you must first install it. You can do this using pip by running the following command in your terminal:

pip install word2num

💻 Usage

Once installed, you can use word2num to convert numbers expressed in natural language to numerical values. To parse a single string, use the word2num convenience function:

from word2num import word2num

word2num("fifty-seven thousand four hundred and twenty-one")  # 57421

If you need to parse multiple strings, you can create your own instance of Word2Num and call its parse method:

from word2num import Word2Num

w2n = Word2Num()
w2n.parse("one hundred and one")     # 101
w2n.parse("seventeen billion")       # 17000000000
w2n.parse("negative eight")          # -8
w2n.parse("half")                    # 0.5
w2n.parse("one and three quarters")  # 1.75
w2n.parse("one three three seven")   # 1337

Note that these functions will return None if a valid numerical value couldn't be interpreted.

🐻 Fuzzy String Matching

word2num uses fuzzy string matching to help parse misspelled number words.

Default Fuzzy Threshold

By default, word2num uses a fuzzy threshold of 80, which means that it will match a word to a number if the fuzzy score is 80 or higher.

Custom Fuzzy Threshold

You can change the fuzzy threshold by passing a fuzzy_threshold parameter to the word2num function or to the Word2Num class constructor:

# Using the word2num function
word2num("soxteeeen", fuzzy_threshold=60) # [16]

# Using the Word2Num class
w2n = Word2Num(fuzzy_threshold=60)
w2n.parse("twoo hunrdered and twienty-too")  # [222]

Disable Fuzzy Matching

To disable fuzzy matching (exact matching only), you can set the fuzzy_threshold to 100:

w2n = Word2Num(fuzzy_threshold=100)
w2n.parse("two hundered and twinty-two")  # None
