博客围绕文本文件中名字得分总和的计算展开。需对包含五千多个名字的文本文件排序，算出每个名字中字符在字母表位置总和，再乘以其在排序后列表中的位置得到名字得分，最后求所有名字得分总和。

Problem 22

Using names.txt (https://projecteuler.net/problem=22)(right click and 'Save Link/Target As...'), a 46K text file containing over five-thousand first names, begin by sorting it into alphabetical order. Then working out the alphabetical value for each name, multiply this value by its alphabetical position in the list to obtain a name score.

For example, when the list is sorted into alphabetical order, COLIN, which is worth 3 + 15 + 12 + 9 + 14 = 53, is the 938th name in the list. So, COLIN would obtain a score of 938 × 53 = 49714.

What is the total of all the name scores in the file?

整理文本文件，排序，将每个名字中每个字符在字母表中的位置总和乘以这个名字在排序后的列表中的位置，最后得到的所有名字总和为?

names = []
with open('p022_names.txt') as f:
    for line in f:
        for i in line.split(','):
            names.append(i[1:-1])
names.sort()
alphabet = [chr(i) for i in range(65, 65+26)]
total = 0
for name in names:
    count = 0
    for char in name:
        count += alphabet.index(char) + 1
    index = names.index(name) + 1
    total += (count * index)
print(total)
