csv文件读取

from urllib.request import urlopen
from io import StringIO
import csv

data = urlopen("http://pythonscraping.com/files/MontyPythonAlbums.csv").read().decode('ascii', 'ignore')
dataFile = StringIO(data)
csvReader = csv.reader(dataFile)

for row in csvReader:
    print("The album ""+row[0]+"" was released in "+str(row[1]))

上边是读取结果为列表形式，下边用dictReader（）读取城字典形式

from urllib.request import urlopen
from io import StringIO
import csv

data = urlopen("http://pythonscraping.com/files/MontyPythonAlbums.csv").read().decode('ascii', 'ignore')
dataFile = StringIO(data)
dictReader = csv.DictReader(dataFile)

print(dictReader.fieldnames)

for row in dictReader:
    print(row)
