[issue20087] Mismatch between glibc and X11 locale.alias

2018-05-05 Thread Licht Takeuchi 

Licht Takeuchi <lich...@outlook.jp> added the comment:

Hi all,

The locale in the latest Ubuntu 18.04 contains en_IL as valid locale, but 
Python cannot resolve this.
This makes test failure in pandas.
https://github.com/pandas-dev/pandas/issues/20957

en_IL has significant impact because this is English locale and now supported 
in the latest Ubuntu. Is there any plan to add only en_IL?

(Note that I've already created the PR. ( 
https://github.com/python/cpython/pull/6707 ))

[issue33432] No locale alias mapping key for en_IL

2018-05-05 Thread Licht Takeuchi

The new locale en_IL is added to glibc.
But there is no key for this in the locale alias mapping.

2017-12-09 Thread Licht Takeuchi 

Licht Takeuchi <lich...@outlook.jp> added the comment:

The current implementation does not quote in most case. IOW, the patch which 
makes all '' is quoted is the breaking change (Note that there are some 
applications does not use quoting).

[issue32255] csv.writer converts None to '""\n' when it is first line, otherwise '\n'

2017-12-09 Thread Licht Takeuchi 

Licht Takeuchi <lich...@outlook.jp> added the comment:

I think the first one is buggy and there are two reasons.

1. The both are valid CSV. The double quoting is unnecessary. Some other 
applications, eg. Excel, does not use the double quoting.
Also, the current implementation make to quote only if the string is '' and the 
output is at the first line.

2. '' is not quoted when the two columns case.
## Input:
```
import csv
fp = open('test.csv', 'w')
w = csv.writer(fp, dialect=None)
w.writerow(['', ''])
w.writerow(['3', 'a'])
fp.close()
```
## Output:
```
,
3,a
```

These seem inconsistent and the quoting is unnecessary in this case.

Inconsistent behavior while reading a single column CSV.
I have the patch and waiting for the CLA response.

# Case 1

fp = open('test.csv', 'w')
w = csv.writer(fp)
w.writerow([''])
w.writerow(['1'])
fp.close()

1
```

# Case 2

```
import csv
fp = open('test.csv', 'w')

w.writerow(['1'])
w.writerow([''])
fp.close()
```
