2.第二种方式

# coding=utf-8
from pymongo import MongoClient
import csv, time, re
# 链接mongodb数据库客户端
client = MongoClient('127.0.0.1', 27017)
# 链接mongodb数据库集合
crimes = client['test']['crimes']
# 将所有数据全部插入到对应集合中
# crimes集合
_data = csv.reader(open('crimes.csv', 'r'))
count = 0
for _ in list(_data)[1:]:
    _json = {
        'id': _[0],
        'case_number': _[1],
        'data': _[2],
        'block': _[3],
        'iucr': _[4],
        'primary_type': _[5],
        'description': _[6],
        'location_description': _[7],
        'arrest': _[8],
        'domestic': _[9],
        'beat': _[10],
        'district': _[11],
        'word': _[12],
        'connuntiy_area': _[13],
        'fbi_code': _[14],
        'x_coordinate': _[15],
        'y_coordinate': _[16],
        'year': _[17],
        'updated_on': _[18],
        'latitude': _[19],
        'longitude': _[20],
        'location': _[21]
    }
    crimes.insert_one(_json)
    count += 1
    print('第' + str(count) + '个数据已经插入成功！' + ' 数据源是:' + str(_json))
