这不是我第一次抓取数据，但感觉确实如此。
import csv
import requests
import os
outfile = open("Labs_StartingGoalies.csv","a",newline='')
writer = csv.writer(outfile)
header=[
"Home_Tm"]
writer.writerow(header)
req = requests.get('https://www.fantasylabs.com/api/lines/4/12-20-2017/startinggoalies')
data = req.json()['GoalieMatchups']
for i, teams in enumerate(data):
for i, team in enumerate(teams['Properties']):
print (team)
输出：
EventId
EventDate
EventDateTime
TimeOfDay
Stadium
HomeTeam
HomeEventTeamId
HomeGoalie
HomeTwitterName
HomePrimarySourceKey
HomeGoalieId
HomeGoalieSalary_DK
HomeGoalieSalary_FD
HomeGoalieStatus
HomeGoalieText
HomeModifiedDate
HomeSourceText
HomeSourceURL
HomeMoneyLine
HomeMoneylineChange
HomeVegasPoints
VisitorTeam
VisitorEventTeamId
VisitorGoalie
VisitorTwitterName
VisitorPrimarySourceKey
VisitorGoalieId
VisitorGoalieSalary_DK
VisitorGoalieSalary_FD
VisitorGoalieStatus
VisitorGoalieText
VisitorModifiedDate
VisitorSourceText
VisitorSourceURL
VisitorMoneyLine
VisitorMoneylineChange
VisitorVegasPoints
下一个代码：
import csv
import requests
import os
outfile = open("Labs_StartingGoalies.csv","a",newline='')
writer = csv.writer(outfile)
header=[
"Home_Tm"]
writer.writerow(header)
req = requests.get('https://www.fantasylabs.com/api/lines/4/12-20-2017/startinggoalies')
data = req.json()['GoalieMatchups']
for i, teams in enumerate(data):
for i, team in enumerate(teams['Properties']):
HomeTeam = team['HomeTeam']
print (HomeTeam)
错误： File "C:/Python36/Projects/NHL/Labs_Teams.py", line 17, in <module> HomeTeam = team['HomeTeam'] TypeError: string indices must be integers
这Json有点难以阅读。通常我使用Mozilla它，但它没有以正常方式显示。我想首先从列表中提取数据，output但所有不同的尝试都失败了。谢谢参观！
for 循环应该修改如下，
for i, teams in enumerate(data):
HomeTeam = teams['Properties']['HomeTeam']
print (HomeTeam)
这将输出
Columbus Blue Jackets
Philadelphia Flyers
Calgary Flames
您不需要内部循环，因为teams['Properties']它是字典，而不是列表。
编辑：另外，由于你没有使用计数器，你不需要枚举数据，它已经是一个列表
for teams in data:
HomeTeam = teams['Properties']['HomeTeam']
print (HomeTeam)
