在python中执行executemany命令时获取KeyError

Question

Python code

import pymysql
import xlrd
import re
import os
import csv
conn = pymysql.connect(host='',
                             user='',
                             password='',
                             db='',
                             charset='utf8mb4',
                             cursorclass=pymysql.cursors.DictCursor)
sql = "INSERT INTO `webscrap_wunderground` (Date,MeanTemp,MaxTemp,MinTemp,HeatingDegree,DewPoint,MeanHumidity,MaxHumidity,MinHumidity,Precipitation,SeaLevel,MeanWindSpeed,MaxWind_Speed,Visibility,Event) VALUES (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)"

with open('C:/Users/SARIKA/Weather Data.csv') as csvfile:
    reader = csv.DictReader(csvfile)
    for row in reader:
        print(row)
        cur = conn.cursor()
        cur.executemany(sql,[(row['Date'],row['Mean Temperature'],row['Max Temperature'],row['Min Temperature'],row['Heating Degree Days'],row['Dew Point'],row['MeanHumidity'],row['MaxHumidity'],row['MinHumidity'],row['Precipitation'],row['SeaLevel'],row['MeanWindSpeed'],row['MaxWindSpeed'],row['visibility'],row['Events'])])

        conn.escape_string(sql)
        conn.commit()

here is error i get when I execute above code. Csv file is read correctly as i have print row from that as shown below. But while inserting data in database table it gives Error. I think there is problem in mapping between csv and database but i couldn't found mistake please help.

OrderedDict([('Date', '2017/1/1'), ('Mean Temperature', '24'), ('Max Temperature', '31'), ('Min Temperature', '16'), ('Heating Degree Days', 'N/A'), (' Dew Point', '16'), (' Average Humidity', '53'), (' Max Humidity', '83'), (' Minimum Humidity', '27'), (' Precipitation', '0.0'), (' Sea Level Pressure', '1012.73'), (' Average Wind Speed', '4'), (' Maximum Wind Speed', '17'), (' Visibility', '2.0'), (' Events', '')])
Traceback (most recent call last):
  File "C:\Users\SARIKA\eclipse-workspace\a1\csvtosql.py", line 20, in <module>
    cur.executemany(sql,[(row['Date'],row['Mean Temperature'],row['Max Temperature'],row['Min Temperature'],row['Heating Degree Days'],row['Dew Point'],row['MeanHumidity'],row['MaxHumidity'],row['MinHumidity'],row['Precipitation'],row['SeaLevel'],row['MeanWindSpeed'],row['MaxWindSpeed'],row['visibility'],row['Events'])])
KeyError: 'Dew Point'

CSV file

Database table structure

Answer 1

查看输出，CSV的列称为“露点”，在“D”之前有一个空格。像那样引用它（即row[' Dew Point']）应该修复错误。
