生成包含字典中随机单词的CSV文件

从buildout获取脚本

>>> import os
>>> gibberish = os.path.join(
...     reduce(lambda path, _: os.path.dirname(path),
...            range(3), __file__), 'bin', 'gibberish')

打印帮助信息

>>> from zc.buildout.testing import system
>>> print system(gibberish+' --help'),
usage: gibberish [options] LINES COLUMN [COLUMN ...]
<BLANKLINE>
Generate lines of CSV consisting of random words from a
dictionary.  The number of lines of CSV must be specified either
as a single integer to specify a fixed number of lines or two
integers separated by a dash to specify that a random number of
lines between the two integers should be used.  The columns are
specified in the same manner where the numbers represent the
number of words in that column for a given line.

options:
  -h, --help            show this help message and exit
  -w WORDS, --words=WORDS
                        File containing the words to be chosen
                        from [default: /usr/share/dict/words]

创建一个包含一行和一列单词的简单文件

>>> import cStringIO, csv
>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1 1'))))
>>> len(result)
1
>>> len(result[0])
1
>>> len(result[0][0].split())
1

确保删除换行符

>>> result[0][0][-1] != '\n'
True

列中有两个单词

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1 2'))))
>>> len(result)
1
>>> len(result[0])
1
>>> len(result[0][0].split())
2

列中有随机数量的单词

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1 1-10'))))
>>> len(result)
1
>>> len(result[0])
1
>>> 1 <= len(result[0][0].split()) <= 10
True

有10行

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 10 2'))))
>>> len(result)
10
>>> len(result[0])
1
>>> len(result[0][0].split())
2

有随机数量的行

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1-10 2'))))
>>> 1 <= len(result) <= 10
True
>>> len(result[0])
1
>>> len(result[0][0].split())
2

有两列

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1 2 3'))))
>>> len(result)
1
>>> len(result[0])
2
>>> len(result[0][0].split())
2
>>> len(result[0][1].split())
3

列中有随机数量的单词，包括零个单词

>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' 1 0-1'))))
>>> len(result)
1
>>> len(result[0])
1
>>> len(result[0][0].split()) in (0, 1)
True

使用小字典测试耗尽字典

>>> import tempfile
>>> _, tmp_path = tempfile.mkstemp()
>>> tmp = file(tmp_path, 'w')
>>> tmp.write('foo')
>>> tmp.close()
>>> result = tuple(csv.reader(cStringIO.StringIO(
...     system(gibberish+' -w %s 1 1' % tmp_path))))
>>> result
(['foo'],)
>>> os.remove(tmp_path)
