使用shell或批处理命令lin将Python Pretty table转换为CSV

Question

有什么简单的方法可以将Python Pretty table的输出转换成语法上可用的格式，比如CSV。在

输出如下：

C:\test>；nova列表

    spu+--------------------------------------+--------+--------+------------+-------------+-----------------------------------+
     | ID                                   | Name   | Status | Task State | Power State | Networks                          |
     +--------------------------------------+--------+--------+------------+-------------+-----------------------------------+
     | 6bca09f8-a320-44d4-a11f-647dcec0aaa1 | tester | ACTIVE | -          |  Running     | OpenStack-net=10.0.0.1, 10.0.0.3 |
     +--------------------------------------+--------+--------+------------+-------------+-----------------------------------+

Answer 1

这是一个非常丑陋的一行

import csv

s = """\
  spu+--------------------------------------+--------+--------+------------+-------------+-----------------------------------+
     | ID                                   | Name   | Status | Task State | Power State | Networks                          |
     +--------------------------------------+--------+--------+------------+-------------+-----------------------------------+
     | 6bca09f8-a320-44d4-a11f-647dcec0aaa1 | tester | ACTIVE | -          |  Running     | OpenStack-net=10.0.0.1, 10.0.0.3 |
     +--------------------------------------+--------+--------+------------+-------------+-----------------------------------+"""

result = [tuple(filter(None, map(str.strip, splitline))) for line in s.splitlines() for splitline in [line.split("|")] if len(splitline) > 1]

with open('output.csv', 'wb') as outcsv:
    writer = csv.writer(outcsv)
    writer.writerows(result)

我可以把它打开一点使它更漂亮：

^{pr2}$

或者可能更有用：

result = []

for line in s.splitlines():
    splitdata = line.split("|")
    if len(splitdata) == 1:
        continue  # skip lines with no separators
    linedata = []
    for field in splitdata:
        field = field.strip()
        if field:
            linedata.append(field)
    result.append(linedata)
