How Can I Convert Number Words (e.g., \'one\') to Integer Values (e.g., 1)?

Can Number Words Be Converted to Integer Values?

In many scenarios, there is a need to convert number words, such as "one," into integers like 1. This conversion can be pivotal for various purposes, such as data processing or natural language understanding.

Fortunately, there are efficient solutions available to facilitate this conversion process. One such solution involves leveraging a dictionary that maps number words to their corresponding integer values. This dictionary serves as the foundation for a function that iteratively converts text numbers into integers.

The function, aptly named text2int(), begins by initializing the dictionary if it hasn't been done yet. This dictionary contains key-value pairs where keys are number words (e.g., "one") and values are tuples representing the scale (e.g., 1) and increment (e.g., 1).

When converting a text number (e.g., "seven billion one hundred million thirty one thousand three hundred thirty seven"), the function tokenizes the text and processes each word. If a word is not found in the dictionary, the function raises an exception indicating an illegal word encountered.

For each valid word, the function retrieves its corresponding scale and increment from the dictionary. It updates its current value based on these factors and performs necessary calculations. The result of the conversion is obtained by adding the final current value to the cumulative result.

Utilizing this approach, the function can effectively convert a wide range of text numbers into their integer equivalents.

Here's an example of how to use the text2int() function:

textnum = "seven billion one hundred million thirty one thousand three hundred thirty seven"
result = text2int(textnum)
print(result)  # Output: 7100031337
