Question

我从csv文件中获取了多行字符串，并尝试将其转换为dict。我已经编写了下面的代码，我想使用它，但不知道如何使用它。

scsv = '''coupon,    months_to_maturity,    FACE_VALUE,
                0.3758,    12,    100,
                0.7287,    24,    100,
                1.0894,    36,    100,
                1.4019,    48,    100,

您可以执行以下操作：

import os
import csv
from StringIO import StringIO

scsv = """coupon,    months_to_maturity,    FACE_VALUE,
                0.3758,    12,    100,
                0.7287,    24,    100,
                1.0894,    36,    100,
                1.4019,    48,    100,
                1.6542,    60,    100,
                1.8512,    72,    100,
                2.0034,    84,    100,
                2.1213,    96,    100,
                2.2141,    108,    100,
                2.2891,    120,    100,
                2.3516,    132,    100,
             """

scsv = scsv.replace(' ','')  #remove white spaces
scsv = scsv.replace(',' + os.linesep, os.linesep) #remove commas at the end of the lines

f = StringIO(scsv)
reader = csv.DictReader(f, delimiter=',')
rows = [row for row in reader]

print rows[0]
# {'coupon': '0.3758', 'months_to_maturity': '12', 'FACE_VALUE': '100'}
