How to Convert Numeric Words into Numbers using Python
Challenge
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 fortysix” => 246
 “seven hundred eightythree 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 twentyfour” 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
