Python to convert Chinese numbers to Arabic numerals,

This article describes how to convert Chinese numbers to Arabic numerals using Python. We will share this with you for your reference. The details are as follows:

I. Requirements

Today I wrote three thousand two hundred lines of code. Today I wrote 3200 lines of code.

The two rows have the same meaning, but they are not the same expression.

Ii. Principles

Number features are numbers + units, such as three hundred, nine thousand and two
You can traverse from the back to the front. If you encounter a number ranging from 0 to 9, multiply it by the unit of the previous digit. If you encounter a new unit (10 million), replace it with a number for the next digit.

Iii. Example

Five hundred and forty-three 1. 3 --> 3 3 <10: total = 32. 10 --> 10, 10 ≥ 10, and not 0: r = 103. 4 --> 4, 4 <10: total = 3 + 4*10 = 434. hundred --> 100, 10 0 ≥ 10, and not 0: r = 1005. 5 --> 5, 5 <10: total = 43 + 5*100 = 543
