Python word to number one

How to Convert Numeric Words into Numbers using Python

Using Python, we want to convert words into numbers. In this challenge, we will explore how to convert a string into an integer.

The strings simply represent the numbers in words. Let’s convert these words into numbers.

Examples:#

• “one” => 1
• “twenty” => 20
• “two hundred forty-six” => 246
• “seven hundred eighty-three thousand nine hundred and nineteen” => 783919

Additional Notes:#

• The minimum number is “zero” (inclusively)
• The maximum number, which must be supported is 1 million (inclusively)
• The “and” in e.g. “one hundred and twenty-four” is optional, in some cases it’s present and in others, it’s not
• All tested numbers are valid, you don’t need to validate them

Test cases to convert words into numbers#

Test.assert_equals(parse_int('one'), 1) Test.assert_equals(parse_int('twenty'), 20) Test.assert_equals(parse_int('two hundred forty-six'), 246) 

The solution in Python to convert words into numbers#

def parse_int(textnum, numwords=<>): # create our default word-lists if not numwords: # singles units = [ "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen", ] # tens tens = ["", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety"] # larger scales scales = ["hundred", "thousand", "million", "billion", "trillion"] # divisors numwords["and"] = (1, 0) # perform our loops and start the swap for idx, word in enumerate(units): numwords[word] = (1, idx) for idx, word in enumerate(tens): numwords[word] = (1, idx * 10) for idx, word in enumerate(scales): numwords[word] = (10 ** (idx * 3 or 2), 0) # primary loop current = result = 0 # loop while splitting to break into individual words for word in textnum.replace("-"," ").split(): # if problem then fail-safe if word not in numwords: raise Exception("Illegal word: " + word) # use the index by the multiplier scale, increment = numwords[word] current = current * scale + increment # if larger than 100 then push for a round 2 if scale > 100: result += current current = 0 # return the result plus the current return result + current
