Python to convert Chinese numbers to Arabic numerals,

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`

Iv. Reference Code

`#-*-Coding: cp936-*-import reimport stringcommon_used_numerals_tmp = {'0': 0, '1': 1, '2': 2, '2': 2, '3': 3, '4': 4, '5': 5, '6': 6, '7': 7, '8': 8, '9 ': 9, '10': 10, '100': 100, '100': 1000, '100': 10000, '100 ': 100000000} common_used_numerals ={} for key in common_used_numerals_tmp: common_used_numerals [key. decode ('cp936')] = common_used_numerals_tmp [key] def chinese2digits (uchars_chinese): total = 0 r = 1 # indicates that the Unit is 10 thousand... for I in range (len (uchars_chinese)-1,-1,-1): val = common_used_numerals.get (uchars_chinese [I]) if val> = 10 and I = 0: # if val> r: r = val total = total + val else: r = r * val # total = total + r * x elif val> = 10: if val> r: r = val else: r = r * val else: total = total + r * val return totalprint chinese2digits ('20140901 '. decode ('cp936') print "-----------------------" print chinese2digits ('12 '. decode ('cp936') print "-----------------------" print chinese2digits ('1970, 0.1 billion, 80,323 '. decode ('cp936 '))`
