在Python中将多行字符串转换为字典

我从csv文件中取得多行字符串，并试图将其转换为字典。我写了下面的代码片段，我想使用它，但不知道如何使用它。在Python中将多行字符串转换为字典

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

你可能想使用['csv.DictReader']（https://docs.python.org/3/ library/csv.html＃csv.DictReader）而不是'csv.reader'。 – dsh

@dsh虽然这会导致一个'DictReader'对象。你能展示如何实现这个？ – user131983

你想在你的字典中键入什么？如果是列标题，请记住，字典是无序的。 – Alexander

你可以这样做：

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'}
