python - python - 如何将CSV变量中的行读入python中的多维数组？

Question

字符串如下所示：

x = '''"High";"10";"Assigned";"2012/06/12 10:11:02"
"Low";"20";"Assigned";"2012/06/12 10:11:02"
"Medium";"30";"Assigned";"2012/06/12 10:11:02"'''

我希望它是这样的：

x = [
[High, 10, Assigned, 2012/06/12 10:11:02],
[Low, 20, Assigned, 2012/06/12 10:11:02],
[Medium, 30, Assigned, 2012/06/12 10:11:02]]

解析这个的最佳方法是什么？

Answer 1

>>> import csv
>>> result = [row for row in csv.reader(x.splitlines(), delimiter=';')]
>>> import pprint
>>> pprint.pprint(result)
[['High', '10', 'Assigned', '2012/06/12 10:11:02'],
 ['Low', '20', 'Assigned', '2012/06/12 10:11:02'],
 ['Medium', '30', 'Assigned', '2012/06/12 10:11:02']]

Answer 2

out = []
for line in x.splitlines():
    out.append( line.split(';') )

或者，在一行中：

out = [line.split(';') for line in x.splitlines()]

Answer 3

使用列表理解的单线：

[line.split(';') for line in x.replace('"','').split('\n')]

给出：

[['High', '10', 'Assigned', '2012/06/12 10:11:02'],
 ['Low', '20', 'Assigned', '2012/06/12 10:11:02'],
 ['Medium', '30', 'Assigned', '2012/06/12 10:11:02']]

并且也摆脱了"只留下单引号的结果'
