Hi,
I noticed there is an odd issue when I am trying to convert a recarray to
list. See below for the example/test case.
$ cat a.csv
date,count
2011-07-25,91
2011-07-26,118
$ cat b.csv
name,count
foo,1233
bar,100
$ python
>>> from matplotlib import mlab
>>> import numpy as np
>>> a = mlab.csv2rec('a.csv')
>>> b = mlab.csv2rec('b.csv')
>>> a
rec.array([(datetime.date(2011, 7, 25), 91), (datetime.date(2011, 7, 26),
118)],
dtype=[('date', '|O8'), ('count', '<i8')])
>>> b
rec.array([('foo', 1233), ('bar', 100)],
dtype=[('name', '|S3'), ('count', '<i8')])
>>> np.array(a.tolist()).tolist()
[[datetime.date(2011, 7, 25), 91], [datetime.date(2011, 7, 26), 118]]
>>> np.array(b.tolist()).tolist()
[['foo', '1233'], ['bar', '100']]
The odd case is, 1233 becomes a string '1233' in the second command. But
91 is still a number 91.
Why would this happen? What's the correct way to do this conversion?
Thanks.
