Python每日一练

前言

人生苦短，我用python【2018.6.13】
最近事情有点多，有几天没写了，正好最近需要统计一下各组排名，也就拿python代替手工了

要求

各组给出其他组的排名，统计每个组最终的得分，第一名为0.5，第二名0.4，以此类推。

代码

# -*- coding:utf-8 -*-
groups = [[3, 2, 5, 4, 6], [1, 3, 5, 6, 4], [5, 6, 1, 2, 4], [3, 2, 1, 5, 6], [6, 3, 1, 2, 4], [5, 1, 2, 3, 4]]
score = [0.5, 0.4, 0.3, 0.2, 0.1]
group_results = [0, 0, 0, 0, 0, 0]


def statics():
    for group in groups:
        for index in range(0, 5):
            if group[index] == 1:
                group_results[0] += score[index]
            if group[index] == 2:
                group_results[1] += score[index]
            if group[index] == 3:
                group_results[2] += score[index]
            if group[index] == 4:
                group_results[3] += score[index]
            if group[index] == 5:
                group_results[4] += score[index]
            if group[index] == 6:
                group_results[5] += score[index]
    return group_results


def main():
    group_results = statics()
    index = 0
    for result in group_results:
        print ("the group {index} is :{grade}\n".format(index=index + 1, grade=result))
        index += 1


if __name__ == '__main__':
    main()

#result：
the group 1 is :1.8000000000000003

the group 2 is :1.5

the group 3 is :1.9999999999999998

the group 4 is :0.6

the group 5 is :1.8

the group 6 is :1.3

感觉sublime有毒，控制台输出中文乱码的问题解决不了，python3计算小数时会有小数点

总结

解放双手！
