AD统计，排名前十的国家每年的论文统计量

1.获取每个国家的论文数量，采取的方法是写好sql语句，直接用sql语句统计数量，可能这种方式速度会比较慢，另外一种方法是把id全部传过来，在本地做统计。

import pymysql
import json
import re
import collections
import json

def get_article_from_mysql(sql):
    conn= pymysql.connect(
            host=‘localhost‘,
            port = 3306,
            user=‘root‘,
            passwd=‘‘,
            db =‘python‘,
            )
    cursor = conn.cursor()

    a = cursor.execute(sql)
    b = cursor.fetchmany(a)
    return b[0][0]

def getsqllist():
    country = [‘USA‘, ‘China‘, ‘UK‘, ‘Germany‘, ‘Italy‘, ‘Japan‘, ‘Canada‘, ‘France‘, ‘Spain‘, ‘Australia‘]
    top_country = []
    for i in country:
        top_country.append(‘%‘+i+‘%‘)

    year = []
    for i in range(1995,2017):
        year.append(str(i))
    print year

    str1 = ‘SELECT COUNT(*) FROM alzheimer where authorinfor like  ‘
    str2 = ‘&& union_kwd_str != \‘\‘ && pub_year = ‘

    countrydict = {}

    for i in top_country:
        sqllist = []
        for j in year:
            sql = str1+"‘"+i+"‘"+str2+"‘"+j+"‘"
            sqllist.append(sql)
        countrydict[i] = sqllist
    return countrydict

def change_with_year():
    countrydict = getsqllist()

    fobj = open(‘1203_topcountry_article_change_with_year.json‘,‘w‘)

    countrylist = [‘USA‘, ‘China‘, ‘UK‘, ‘Germany‘, ‘Italy‘, ‘Japan‘, ‘Canada‘, ‘France‘, ‘Spain‘, ‘Australia‘]
    for country in countrylist:
        this_country_sql_list = countrydict[‘%‘+country+‘%‘]

        this_year_article_num = []
        for sql in this_country_sql_list:
            this_year_article_num.append(get_article_from_mysql(sql))
        data = {
            ‘name‘:country,
            ‘type‘:‘line‘,
            ‘stack‘: ‘total‘,
            ‘areaStyle‘: ‘{normal: {}}‘,
            ‘data‘:this_year_article_num
        }
        print country,this_year_article_num
        json_data = json.dumps(data)
        fobj.write(json_data)
        fobj.write(‘,‘)
        fobj.write(‘\n‘)

#change_with_year()

def article_each_year():
    str1 = ‘SELECT COUNT(*) FROM alzheimer where union_kwd_str != \‘\‘ && pub_year =‘

    all_this_year_article_num = []
    for i in range(1996,2017):
        year = str(i)
        sql = str1+"‘"+year+"‘"
        all_this_year_article_num.append(get_article_from_mysql(sql))

    data = {
        ‘article_each_year‘:all_this_year_article_num
    }

    fobj = open(‘1204_article_each_year_num.json‘,‘w‘)
    json_data = json.dumps(data)
    fobj.write(json_data)
    print all_this_year_article_num

article_each_year()

2）获得每个国家每年的论文信息后，求比例。比如1996年美国的比例 = 1996年美国的论文量/1996年全世界的论文量
