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)
