[英]How to read data from a csv file using API in Python
我正在嘗試從以下鏈接下載數據:
NHTSA網站
如果我按以下方式創建鏈接,則它將CSV文件下載到我的計算機上http://webapi.nhtsa.gov/api/SafetyRatings/modelyear/2019/make/ACURA/model/RDX?format=csv
如何使用Python中的API讀取不同車輛的此文件?
到目前為止,這是我的代碼:
db = sql.connect("localhost","root","password","TEST")
cursor = db.cursor()
sql = "SELECT * FROM TEST.car_model"
cursor.execute(sql)
data = cursor.fetchall()
for row in data:
apiUrl = "http://webapi.nhtsa.gov/api/SafetyRatings/modelyear/"
apiParams = str(row[1])+"/make/"+row[2].replace(" ","%20")+"/model/"+row[3].rstrip().replace(" ","%20")
apiFormat = "?format=csv"
link = apiUrl + apiParams + apiFormat
response = urlopen(apiUrl + apiParams + apiFormat)
f = open(link, 'rb')
reader = csv.reader(f)
for row in reader:
print(row)
db.close()
響應會自動將文件下載到我的“下載”文件夾中嗎?
你可以試試這個
model = input("Enter model name: ")
year = input("year: ")
url = "http://webapi.nhtsa.gov/api/SafetyRatings/modelyear/"+year+"/make/ACURA/model/"+model+"?format=csv"
import urllib.request
with urllib.request.urlopen(url) as response:
html = response.read()
with open(model+year+".csv", "w") as f:
f.write(html)
您可以在網址中添加更多變量。 然后,您可以使用pandas軟件包進行閱讀。
import pandas as pd
vechiles = pd.read_csv("vichles.csv")
