Python正确解析CSV

以下方法效果很好

d = {}d['column1name'] = []d['column2name'] = []d['column3name'] = []dictReader = csv.DictReader(open('filename.csv', 'rb'), fieldnames = ['column1name', 'column2name', 'column3name'], delimiter = ',', quotechar = '"')for row in dictReader:    for key in row:        d[key].append(row[key])

这些列存储在字典中，其中列名称为键。
